John The Ripper Gpu Windows

John the Ripper is a free and open source software. It is a dictionary-based free password cracking tool that attempts to crack plaintext ciphers in the case of knowing the ciphertext, it fully supports the most current encryption algorithms such as DES, MD4, MD5, etc. Simply speaking, it is a brute force password cracking. Based on OpenBenchmarking.org data, the selected test / test configuration (John The Ripper 1.9.0-jumbo-1 - Test: Blowfish) has an average run-time of 2 minutes.By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result. John the Ripper is a fast password cracker, currently available for many flavors of Unix, macOS, Windows, DOS, BeOS, and OpenVMS (the latter requires a contributed patch). Its primary purpose is to detect weak Unix passwords. John the Ripper 1.7.9-jumbo-6 supported GPUs for the following hashes and non-hashes: Latest release include more formats and latest git trees include even more. CUDA significantly benefits from compile-time tuning of parameters for a given GPU, see doc/README-CUDA. WPA-PSK CUDA uses a little bit of CPU code as well, and benefits from OpenMP (so you'll get slightly faster speed if you enable OpenMP in the JtR build, although you'll load multiple CPU cores then).

John the Ripper (JtR) is one of the hacking tools the Varonis IR Team used in the first Live Cyber Attack demo, and one of the most popular password cracking programs out there. In this blog post, we are going to dive into John the Ripper, show you how it works, and explain why it’s important.

Prison school ova dubbed. Notes about hacking: Hacking is a pursuit of knowledge about systems, design, and humans. In this case, we are talking about software and operating systems.

“This really opened my eyes to AD security in a way defensive work never did.”

Hacking is not necessarily criminal, although it can be a tool used for bad intentions. We advocate for ethical hacking. Stay in the light side of the Force.

How Does John the Ripper Work?

JtR supports several common encryption technologies out-of-the-box for UNIX and Windows-based systems. (ed. Mac is UNIX based). JtR autodetects the encryption on the hashed data and compares it against a large plain-text file that contains popular passwords, hashing each password, and then stopping it when it finds a match. Simple.

In our amazing Live Cyber Attack demo, the Varonis IR team demonstrates how to steal a hashed password, use JtR to find the true password, and use it to log into an administrative account. That is a very common use case for JtR!

JtR also includes its own wordlists of common passwords for 20+ languages. These wordlists provide JtR with thousands of possible passwords from which it can generate the corresponding hash values to make a high-value guess of the target password. Since most people choose easy-to-remember passwords, JtR is often very effective even with its out-of-the-box wordlists of passwords.

JtR is included in the pentesting versions of Kali Linux.

What is John the Ripper Used for?

JtR is primarily a password cracker used during pentesting exercises that can help IT staff spot weak passwords and poor password policies.

Here is the list of encryption technologies found in JtR:

UNIX crypt(3)

Traditional DES-based

“bigcrypt”

BSDI extended DES-based

FreeBSD MD5-based (linux and Cisco IOS)

OpenBSD Blowfish-based

Kerberos/AFS

Windows LM (DES-based)

DES-based tripcodes

SHA-crypt hashes (newer versions of Fedora and Ubuntu)

SHA-crypt and SUNMD5 hashes (Solaris)

That’s the “official” list. JtR is open-source, so if your encryption of choice isn’t on the list do some digging. Someone might have already written an extension for it.

How to Download John the Ripper

JtR is an open-source project, so you can either download and compile the source on your own, download the executable binaries, or find it as part of a penetration testing package.

The official website for John the Ripper is on Openwall. You can grab the source code and binaries there, and you can join the GitHub to contribute to the project.

JtR is available on Kali Linux as part of their password cracking metapackages.

Tutorials for Using John the Ripper

We are going to go over several of the basic commands that you need to know to start using John the Ripper. To get started all you need is a file that contains a hash value to decrypt.

If you ever need to see a list of commands in JtR, run this command:

Cracking Passwords

John the Ripper’s primary modes to crack passwords are single crack mode, wordlist mode, and incremental. The single crack mode is the fastest and best mode if you have a full password file to crack. Wordlist mode compares the hash to a known list of potential password matches. Incremental mode is the most powerful and possibly won’t complete. This is your classic brute force mode that tries every possible character combination until you have a possible result. Iobit folder lock crack.

The easiest way to try cracking a password is to let JtR go through a series of common cracking modes. This command below tells JtR to try “simple” mode, then the default wordlists containing likely passwords, and then “incremental” mode.

You can also download different wordlists from the Internet, and you can create your own new wordlists for JtR to use with the –wordlist parameter.

If you want to specify a cracking mode use the exact parameter for the mode.

Word Mangling Rules

Mangling is a preprocessor in JtR that optimizes the wordlist to make the cracking process faster. Use the –rules parameter to set the mangling rules.

Viewing Your Output

When you want to see the list of passwords that you have cracked, use the –show parameter.

If your cracked password list is long, you can filter the list with additional parameters. You can also redirect the output using basic redirection in your shell. For example, if you want to see if you cracked any root users (UID=0) use the –users parameter.

John The Ripper Gpu Support Windows

Or if you want to show users from privileged groups use –groups.

Below is the JtR command from our Live Cyber Attack Webinar. In this scenario, our hacker used kerberoast to steal a Kerberos ticket granting ticket(TGT) containing the hash to be cracked, which was saved in a file called ticket.txt. In our case, the wordlist used is the classic rockyou password file from Kali Linux, and the command was set to report progress every 3 seconds.

Password cracking a Word document or an Excel file hasbecome much easier. Previously you hadto rely on a flaw in the document, some sketchy software or an even sketchierwebsite. Since October 2014 OclHashcat now supports cracking the documentspassword. The process is simple but notas straight forward as a novice might want. You need a couple of things agraphics card capable of cracking using GPU’s, such as an NVidia card with cudasupport, OclHashcat version 1.31 or greater, python, and a password protecteddocument.

I’m writing this for Windows because, let’s face it if youlost a password for Word, Excel or Powerpoint you probably have Windows. First go to hashcat.netgrab the correct OclHashcat version for your GPU either AMD or NVidia. Download it and unzip it, you may need 7zipif you can’t unzip the file. Next, you need python, get that here python.org.(I’m not going to say use Python 2.7 or Python3 just grab whatever, I just use2.7.) Grab the installer, and install it. You also need a python script calledoffice2john and you can get that here office2john.Long story short john the ripper another password cracking suite is alsocapable of doing this, but I prefer OclHashcat.

Now, we have everything we need to recover that passwordright? Nope, we need one more thing some dictionaries to use with OclHashcat.Get those from SkullSecurity. You can move on torule attacks or brute force if the dictionaries fail. One of my first go tolists is the rockyou list start there.

Let’s get cracking, open up a command prompt and navigate tothe directory with the office2john.py file and the password protectedfile. Enter: python office2john.py FILENAME, filenamebeing the protected document. After a second you will see the output likebelow:

Book1.xlsx:$office$*2010*100000*128*16*657ca4864bf8f86a617d21cb71b0c572*0d689a95b0e6ddca4c6f0b3b2c30cc46*1b4c305643f3a7da83f0671df10e80e6ed4d6c576129406f79dd6526ca34f153

This is the hash of the password that protects the document,the important part here is highlighted as we need to tell OclHashcat what typeof hash this is. This one is an Office 2010 document. From the command prompt navigate to where youhave OclHashcat actually CudaHashcat for me. Entering --help after thecudahashcat32.exe or cudahashcat64.exe will show you the hash type numbers andyou pick the one that matches your office version you see in the extracted hashabove.

Since the document is Office 2010 I need hash type 9500.Here is my command

John The Ripper For Windows

“cudaHashcat32.exe -a 0 -m 9500 --username Book1.xlsx:$office$*2010*100000*128*16*657ca4864bf8f86a617d21cb71b0c572*0d689a95b0e6ddca4c6f0b3b2c30cc46*1b4c305643f3a7da83f0671df10e80e6ed4d6c576129406f79dd6526ca34f153'D:password_listsskullsecurity-listsskullsecurity-listsrockyou.txt'

-a 0, specifies dictionary attack mode

-m, is the hash type

--username, tells hashcat to ignore the usernamein this case the username is “Book1.xlsx”

The next part is the hash followed by the dictionary.Running this will result in the output similar to below.

In the image the hash was cracked in 4 seconds with thepassword being “Password”. If thatdoesn’t work try another dictionary use rules or try to brute force. Keep inmind that a brute force can take a LONG TIME.

Install John The Ripper For Gpu Windows

Even brute forcing a 6 character password with uppercase,lowercase and numbers can take more than a year. Obviously, the better or moreGPU’s you have the faster it will be. Long story short:

John The Ripper Password Cracker

Run office2john.py to get the hash of the protected document

Run OclHashcat on the hash

A Wife’s Surprise: Or How I Learned to Stop Worrying And Pervert My Wife

That day started like any other Tuesday. It was 11am, I just had my 3rd cup of coffee, sitting at my desk running scripts to see if there were any oddities in the system logs that belong to my clients. I was a bit surprised to find my wife coming through the front door. She was normally at work at this time. Allow me to give some background on us. My wife and I have been married for 2 years. We had been dating for 5 years before that. Our relationship was a LDR one for quite some time. We were trying to decide who would be the one to move, but after a long time of debate and traveling back and forth we both decided to move to an “in-between place” from where we’re both originally from. I’m European and 35 years old, while my wife is South East Asian and just turned 30. I stand about 6 foot and built like a boxer, while she’s only 5’5”, and has an amazing body. Her A-cup breasts made her deliciously plump ass stand out even more. Her friends always joked she as a ‘black girls’ butt’. I work as a mobile PenTester, she’s a medical specialist. She comes from a very religious background, whereas I… Let’s just say I was quite the pervert compared to her. Specifically, I’m big into exhibitionism, and she was a virgin before we met. People always say “opposites attract”, but we were so opposite sometimes, no one could understand what we saw in each other. Truth is, I love how grounded she is, and she loves how adventurous I am. After we were married, however, I made it a personal mission to make my wife as sexually perverted as I am. Most people think that getting their wife to try anal might be a huge step. For me, anal comes after she had gotten use to role playing. Our favorite role-play was always her being some random prostitute, and I, a John, looking to use her body for money. After a year and a half, and about a dozen visits to a swingers club to just “enjoy drinks and see what others do”, my wife finally felt confident and comfortable enough for us to finally have sex at the swingers club, but only with each other. She really enjoyed it. So much in fact, we found ourselves at the club at least once a month. I thought I was making good progress. I was breaking her out of her shell. I could be open about all my fantasies with her, and she could be with me. But I didn’t realize what I had awaken in her until that Tuesday she came home out of no where. That all my progress had made her seek out things I had only mentioned in the heat of passion. Before I got a chance to stand up to greet her, she came over and sat on my lap. Dropping her bag on the floor, kissing me, asking me if I was busy. I wasn’t too busy and didn’t really need to take calls then. She smiled, jumping up and grabbing her bag. “I’ve got a surprise for you” she said with a slightly mischievous tone. “Oh? And what would that be?” I smirked. Saying nothing, she pulled something out of her bag. Holding it behind her, she told me to close my eyes. As I did I felt her come up to me and kiss me passionately then pull her mouth away slowly. Telling me to keep my eyes close, I felt her slowly walk behind my chair. “Put your hands together behind your chair” she instructed me. I didn’t expect that, but I knew she was up to something naughty so I did as she asked. Suddenly I felt her putting something furry around my wrists, and with ‘zzztttt’ sound, I opened my eyes realizing she put handcuffs on me. As she came back around and smiled. “Well what sort of surprise is this then” I asked. She said nothing as she got down on her knees in front of me and started unzipping my pants. As she pulled my limp cock out, I moaned in lustful anticipation. Feeling her warm mouth engulf my cock made the rest of my body surrender and go limp. She always loved getting me hard with her mouth. Within 30 seconds she had me fully erect. As I looked into her eyes, I moaned out and swearing. My cock may only be 7 1/2” in length, but the 5 1/2” girth made me thick enough that she couldn’t wrap her hand around it completely. And while my wife may have a small mouth, she learned how to deep throat every inch me. As she grabbed the base of my cock, she place her tongue against the back of the head. She slowly started pulling her hand up along my shaft, milking me, letting my precum ooze out onto her tongue. As she got half way up my shaft, she wrapped her beautiful lips around my head and started to suck the rest out. The only response I could give was to throw my head back and yell “ah! Baby! Fuck!” As she took her mouth off my cock, she stood up and let me watch her reach up under her dress and slowly take her panties off. With a seductive smile, she brought the crotch of her panties up to my face to let me see how wet they were. “Mmmm, do you like knowing a big cock in my hands and mouth make me so wet?” she asked in her seductive moaning voice. I just nodded my head and stuck my tongue out to get a taste of her juice stain. She told me to open my mouth nice and wide, and I did as I was told. Without a word she pushed the crotch of her panties into my mouth, then pushed the rest of her panties into my mouth, effectively gagging me. My wife has never restrained or gagged me before, so this was becoming exciting. Then she went back to her purse and pulled out a small USB stick. “This is the surprise” she exclaimed. Turning my chair around to face my screen and putting the USB stick into the computer. I was not prepared for what she had in store.

“You know I love you, hun. So I listen to things you tell me.” she told me as she was opening the USB on my computer. “Do you remember how hard you came the last time we were at the club? And what made you cum so hard?” I really had to think for a moment, then she helped remind me. We were at the club about three weeks ago. We had been having sex for a while on one of the couches. She was riding on top of me, and I noticed a couple in front of us. The woman stroking a man’s cock, as he fingered her pussy. I knew they were getting off watching us. So I made my wife lean up against me, and I grabbed her ass cheeks and spread them wide apart so they could get a good view. I knew how good it must look for them. Seeing her lips grip tightly on my cock as her asshole would wink from time to time. “Ohhh baby are you showing me off again?” she asked lustfully in my ear. “Of course” I whispered. “Mmmm what do you think I am, some porn girl, huh?” Her question made me moan. “Aaahhhh fuck, baby you know you’ve got a body made for porn” I said feeling myself get closer as we continued our dirty talk. “Yeah?” she moaned. “You like thinking of me fucking on camera? Getting paid to be fucked? Having other people jerk off to it?” I couldn’t contain myself, and just started slamming my cock up inside her body as I shot my cum up into the back of her pussy. As I came, her walls contracted with her orgasm, milking my cock for every drop. It was hot. As she doubled clicked on a file, I saw it was a video. “You remember how hot it was. So last weekend, I decided to have a surprise made for you.” As she went to my side, the video started playing, and to my shock, my wife was saying hello to the person behind the camera. She sat on the bed fully clothed, and the logo of a porn company watermarked in the bottom corner.

She was being interviewed. She of course gave the camera man a fake name, telling a bit about herself. He asked her why she decided to do her first porn, I was shocked yet turned on by her answer. “Well, my husband always tells me that I’ve got a body for porn, so I thought it would be fun to give it a try.” she said with a giggle. “Oh so you’re married?” the cameraman asked. “So does your husband know you’re doing this?” She laughed “Yes, I’m happily married. He doesn’t know I’m doing this yet, but he will.” I couldn’t believe how honest she was. The cameraman continued his interview. “So is he also Asian?” “No no no. He’s a white guy.” She told him in such a corrective tone. “Ah ok. So when was the last time you had sex?” He asked. “Well, about 3 days ago” she answered him. “And that was with your husband?” She laughed “Of course it was with my husband!” The cameraman laughed in return. “Well I was just checking. How many guys have you had sex with outside of your husband then?” “Just him” she said proudly. “Wait, you’ve never had sex with anyone other than your husband?” he asked kinda shocked. “Nope, just him. I lost my virginity to him” she explained. “Wow!” The cameraman was genuinely shocked. “So this will be the first time you’ve ever had a different cock?” the cameraman asked. She laughed nervously “I guess it is.” “Are you nervous?” he asked. “Of course! A little bit excited but really nervous too!” she exclaimed with a nervous laugh. “Well you don’t have to be nervous, we want you to have a good time, ok?” he told her to reassure her. I couldn’t believe it. This was the woman who, when we started dating, was telling me how sacred the martial bed is. Now here she was on camera for a porn site, telling someone how “nervous and excited” she is about getting fucked by a complete stranger for the first time. As I watched my wife kept stroking my cock. When I looked at her she’d just push my head to keep me watching the screen. As the cameraman kept asking her questions, she stood up, still stroking my hard cock, whispering in my ear. “The fact that your cock is still hard tells me you like the surprise, you know that?” She kept stroking me, breathing into my ear as I continued to watch her on screen. She was now taking her clothes off, showing her delicious body. As she finally took her bra off and exposed her tits, the cameraman came up close to get a good shot of how her nipples were already hard. Telling her how nice her breasts were. As she unbuttoned her shorts, he told her to turn around to take them off. As she did so, she slid her panties down with her shorts, exposing her luscious ass. Bending over, showing the camera here rear pussy. She stood up and turned back around, one hand on her hip, biting her bottom lip as she smiled. “Wow” the cameraman started again “your husband is right, you do have a body made for porn.” She laughed out loud telling him ‘Thank you’. I couldn’t help but moan right then. It wasn’t just because my wife was stroking my cock, but watching triggered something primal in me I never felt before. She whispered in my ear again “See. You’re right. You like knowing other people think your wife is made for porn too don’t you?” I moaned and nodded. In the back of my mind, I know I was suppose to be angry, hurt, jealous, or maybe all three at the same time. But I wasn’t. I actually felt proud. It turned me on so much to hear someone compliment my wife’s naked body.

The cameraman told her to lay on the bed and spread her legs. As she did so, she instinctively started playing with her pussy. I could see she was already a little wet, but also quite nervous as she did so, looking off to the side from time to time. “The guy that was gonna fuck me.. Umm.. Well, I forget his name. Anyways, he was standing off to the side jerking off watching me. So I was nervous, obviously.” she whispered as she wiped up some of my precum with her fingers and licked it off. “Mmmm, you’re really enjoying this huh?” I just hummed that I was through the panty-gag she put in my mouth. Suddenly a naked guy, tall and built like a swimmer, walked over to the side of the bed. His veiny white cock already rock hard. He grabbed her legs and pulled her over to his side of the bed. I could see the nervousness on her face. Then suddenly, as he started rubbing the bare head of his cock against her pussy lips, her face went from nervous to ‘curious anticipation’. “I don’t know what happened, but the moment his cock touched my pussy lips, I stopped being nervous and got really excited.” she continued telling me as she jerked my cock “It was like, at first I was wondering if it was wrong, you know? That I was about to let some stranger have what should only belong to my husband” as she said this she started jerking my cock faster “but the moment I felt his cock touch my pussy that thought vanished and it was like my body took over, telling me this is what I should be doing”. As I watched him start pushing his cock into her pussy, she moaned out in pleasure, and I almost came. But my wife let go of my cock, giggling in my ear “nooo nooo nooo, you have to watch everything before you’re allowed to come.” As I was coming down off my edge, my wife grabbed my cock once again and continued to slowly stroke it. I looked back at the screen. The actor was going slow and steady, pumping maybe 3/4s of his cock in and out of her pussy. He was thick enough to be making her lips stretch around his shaft. My wife may have a small pussy, but it stretches and grips so nicely. “I have to admit, he may have been a little bit longer than you, but he wasn’t as thick as your delicious cock, baby” she whispered in my ear. To be honest, the thought of whether he was bigger than me never crossed my mind. All I knew was my wife looked amazing getting fucked on that bed. I was happy he had ‘big dick’, because at least she’d be able to enjoy herself. As she played with her tits looking down at his hips thrusting against her, she reached down with one hand and started playing with her clit. “Mmmm fuck me deeper” she moaned out. Fuck, she was going to cum already. He turned his hips slightly and start thrusting his cock balls deep inside her. As his meat slid in and out, you could hear the splashing sounds of her juices, and the see his balls swinging low and slapping between her ass cheeks with every thrust. She moaned out loud as she arched her back and hips. She was cumming all over his cock. As I started to moan out, my wife let go of my cock to make sure I wouldn’t cum yet. “That’s just the first orgasm I had of many if you want me to be honest” she told me in her lustful tone. All I could think of then, is how I have been in his position before. When she cums like that I normally make her suck and lick her juices off of my cock. And before I could finish my own thought, I watched as my wife sat up on the bed and immediately started licking and sucking on his cock. I taught her so well. She played with his balls, sucking wildly on his shaft like she hadn’t had a dick in her mouth in months. I couldn’t blame her. It would be a shame if she didn’t taste the cock that just made her cum so good. As I noticed the wet stain on the bed my wife started stroking my cock again, and then I watch on screen as she started deepthroating his dick. Taking his cock down her throat til his balls were right against her chin, hold it, then take it back to just the head. “You taught me so well, you know that?” she whispered in my ear. It took us months of practice before she could finally deepthroat me like that. Now here she was taking this guys cock balls deep into her throat like it was nothing. I know by now I should have been trying to stop watching, but I couldn’t. You couldn’t tell me it was wrong. I always would tease her how her body and sexual talents told me she was ‘made for sex’. But actually seeing how talented and hot she is one camera was the hottest thing I had ever seen up to that point.

As she pulled her mouth off his cock with a smile the video transitioned to a side shot of my wife on her knees getting fucked doggy style by this guy. She whispered in my ear “He asked me to stop because I almost made him cum, that’s why my smile was so big, hun.” It’s too bad, because I wasn’t sure how much longer I could take this delicious torture. As the video continued, I understood why they used him. His thin swimmers physique made his cock stand out more. His abs flexed as he pumped my wifes’ pussy, balls slapping her clit as he bucked his hips. I’m a pretty healthy and well built guy myself, don’t get me wrong. If him and I got into a fight, I’d snap him in half. I didn’t see this guy as ‘superior to me’ or anything like that. But he was young and built like a model, and that just made me feel proud knowing she is so attractive and seductive that she could get such guys horny and wanting to fuck her. Hearing my wife moan on video made my attention go back to her reactions. She was gripping the sheets, twisting them in her fists, burying her face into the bed as she moaned out in agonizing pleasure. Her back remained in a deep arch, forcing her ass up in the air, ensuring she remained fully exposed to take every inch of that cock. She turned her head and started looking directly into the camera. I swear I could see her eyes light up right then, and she started grinding her teeth again wincing in pleasure. I think she forgot for a moment she was being filmed. Then the cameraman stood up and started moving the camera to get a POV shot from behind. My wife was stroking my cock at a steady pace now, breathing heavy into my ear, telling me the nasty details that were in her mind at the time. As we both saw the shot from the actors point of view, I heard her slightly gasp in excitement right into my ear. “Wow, ok. I haven’t seen this video yet either, baby” she said. “I mean, holy shit, I look so fucking hot bent over like that. How come you never told me my pussy looks so good getting fucked from behind like that?” I obviously have but couldn’t answer her right now. As the camera continued to film, I could hear my wife moaning out, starting to cum on this guys cock once again as he kept slowly sliding his cock in-n-out of her beautifully messy hole. You could clearly see her pussy cream smearing all over his shaft, slowly oozing out the sides of her gripping pussy lips. I heard the cameraman comment “fuck dude, she is creaming all over your cock.” and the actor spoke simply in a low voice, “fuck yeah.” I know from personal experience you can’t really say much in that kind of moment. Her scent becomes too intoxicating when she cums. You can’t really think logically. All you know is you want to keep pleasuring her. My wife continued to make me edge throughout the video. Seeing her fuck and cum in different positions. Constantly teasing me with whispers in my ear of how she enjoyed it, how ‘we should try this’. In one scene where she laid on her side, one leg up and the actor thrusting his cock inside her, the cameraman asked her if she was enjoying herself. She nodded into the camera and turned her attention back to the big cock fucking her pussy. Suddenly my wife paused the video and told me that she almost came when the cameraman asked her this next question. Before she hit play, she turned back to me and whispered in my ear once again “but I did cum hard when I thought about the question he asked after this question.” As she hit play on the video and continued jerking me off, I heard the cameraman ask her “So do you think your husband is gonna jerk off to this video?” I could see her expression slighty change from agonizing pleasure to naughty surprise as she nodded yes. Suddenly he asked his second question. “Do you like knowing other people are gonna be jerking off to this video?” She didn’t respond with a verbal answer, instead after a few seconds she reached down and started rubbing her clit furiously as she started cum all over this guys cock again. Looking up at him as her legs started to shake. As I watched her reaction on the screen, my wife grabbed the base of my cock tightly, and said “You did that to me, you know? Perverting me and taking me to that swingers club so often. I use to be such a good girl. Now look at what I’m doing. This is suppose to be a punishment but you’re such a pervert, you’re enjoying it.” She let go of my cock so I could calm down, she knew her words were gonna make me cum.

She continued to tease me and cause me to edge. Letting go of my cock, refusing to let me cum, forcing me to watch her get fucked and cum over and over again. Whispering nasty things in my ears every time she did this. Reminding me what a ‘pervert I am for enjoying this’ and asking if I ‘planned on her ever going this far’. This was becoming torture in the most wonderful way for me. The only thing I didn’t like about all of this, was that I couldn’t fuck her myself right now. As much as I enjoyed seeing her like this, every fiber of my body was only wanting to fuck her myself now. Sexually remind her that, even though I enjoy what she’s doing, why she married me. Finally after an hour the video transitioned to a scene I was looking forward to.

She laid on her back with her hands on her lower thighs, close to her ass cheeks, pulling her legs back so that her pussy was raised upward. The guy had his cock positioned so that his head was between her pussy lips, just poking into her wet entrance. He kept one leg up so you could see her face unobscured between her legs. As he slowly pushed his cock down into her pussy, her lips and tiny slit stretched around his girth. Inch after slow inch of his veinded length disappeared inside her. She took in a slow deep breath as her expression became one of torturous lust, feeling the thickness of his delicious dick eagerly and deliberately forcing her inner walls to spread around it. He stopped and slowly pulled back, letting the camera get a shot off just how tight his balls were raised against the back of his cock. As my wife continued stroking my cock, my own balls raised against me as well, then she whispered in my ear “Since he..” she paused “.. shit I still can’t remember his name” she laughed then continued “since he made me cum so much, and since you always tell me I should never waste cum, when they asked where I would like him to shoot his cum..” she stroked my cock faster “...I told them they should just make it a creampie scene.” I moaned as she let go of my cock, we both looked down and saw it twitching, but the lack of her touch made me calm down before I could cum. “Mmm, you excited to watch me get cum in my pussy” she moaned in my ear as I heard her smear my precum onto her pussy with her freehand. My balls were starting to ache from this lack of orgasm as she whispered in my ear again with her sexy whining voice “Baby, you know when I cum so much I NEED cum in my pussy. I know you understand.” Of course I understood because I taught her that.

As I watched again in erogenous anticipation, I saw my wife’s face start to wince and wrinkle up as her aching pussy continued to be fucked. She whined and whimpered as her eyes stayed focused on his cock pounding in and out of her slightly red and sore looking pussy. I could tell this was going to be a powerful orgasm for her. “I was so close but the head of his cock was just so close to hitting the back of my pussy but it wasn’t, so I couldn’t cum, it was torture baby” she told me as she continued to stroke my cock. The details of everything I saw and heard flooded my mind. How her face looked like she was about to cry out in pain but knowing she just wanted to cum but couldn’t. How her pussy lips gripped tightly on his thick veiny shaft as it pumped in-n-out of her with a beautiful friction. Seeing how her asshole would wink when her pussy walls contracted, a sign of her being even closer to cumming. Her whining and whimpering grew louder. She was starting to mumble something as her breathing grew more shallow and rapid. She looked up at him into his eyes, still whimpering and trying to mumble something to him. After about 30 seconds of her trying to communicate her pre-orgasmic agony to him, she looked back down at his cock and what it was doing to her aching pussy. Her mumbling and whimpering got even louder and more erratic. She started to randomly cry out as the tension of her oncoming orgasm grew beyond what she could bare. Her only release was to dig her nails into her own legs as she screamed. As he started moaning and pounding his cock harder and faster into her slippery pussy hole, she was finally able to communicate a single word. Fuck. Fuck. Fuck. Over and over again, she screamed it out between her whimpers and gasps for air.

As her body forcefully spasmed, my wife let out a scream I could only describe as a mix between a primal scream of pain and pleasure, and the cry of a helpless and vulnerable woman lost in an intoxication of fear and excitement. She was having the most powerful orgasm she had ever had. Looking like she was about to cry, lustfully screaming in orgasmic agony. Holding her legs back still, her eyes stayed focused on her cumming pussy, his powerful cock still thrusting inside her. Her asshole was winking nonstop as her pussy muscles contracted uncontrollably. Her delicious cum cream running steadily out the bottom of her pussy, his pumping cock causing it to gush out from time to time. Her body convulsed at random and her screams started to match up with her convulsions. Suddenly the actor gave out a loud primitive roar as he stabbed his cock hard and deep into her mid-orgasming pussy. She screamed from the violent penetration and her face instantly changed from wrinkled and wincing in orgasmic pain to her eyes bulging out and mouth wide open screaming out in shock. As he continued to grunt, holding his cock where he had planted it inside her, she looked up at him into his eyes for a few seconds moaning into his face after every gasp for air, never changing her expression, until finally she looked back down at his cock, still stabbed deep into her still convulsing pussy. When he pulled just a few of his inches out of her and that’s when I saw what caused her sudden change in expression. His cock continued to violently twitch and pulsate as he shot rope after thick sticky rope of his cum deep into her pussy. As his grunts and moans grew quite, her gasps and moans continued unchanged, and I noticed how her body still jerked at random, how her asshole still winked while his cock continued to pulsate and throb, flooding the inside her pussy. She finally spoke “oh my god” she breathed shallowly “it’s so much cum” she said in a shaky moan. He held his cock inside her, every few seconds still twitching, showing that she getting every last drop inside her still cumming pussy.

My wife.

My sweet, precious wife.

The woman who, two years ago, demanded we wait to have sex til we were married.

Had now been corrupted...by me. She was now so perverted by me, that she had one of the most powerful orgasms of her life.. and it had been given to her by a complete stranger.. a guy who’s name she couldn’t even remember..

But that wasn’t enough... She had to show just how much I really corrupted her.

So she let this stranger drown the inside of her pussy in his cum. And it wasn’t just a little bit. No no no. After he stabbed his cock into her, he had to have had stayed there, buried balls deep inside her pussy, for a full 10 seconds before he pulled it out a little to show how aggressively his cock was painting the inside of her pussy walls with his cum.

And she didn’t stop him. She just kept cumming.

All of it recorded. For a porn site, no less. And what did she have to say about it to me? As I watched the scene, she moaned in my ear “When he first slammed his cock inside me, I thought he might have penetrated my cervix. It hurt, but I was cumming so hard I wasn’t going to tell him to pull out. But when I felt his cock start to twitch inside me, and his cum gushing into me...” she started playing with her pussy as she spoke, jerking me off “I just couldn’t stop cumming after that. Sorry baby but it was too hot not to let me continue cumming in me. Fuck, it was so hot.” “It was so fucking hot”.. My thoughts exactly.

I taught her so well. My mind and cock couldn’t take it anymore. With a herculean cry muffled by my wife’s panties I started to cum as she continued to stroke my cock. The first thick rope of cum shot out so hard it almost hurt. As my wife saw me cumming, she continued to stroke me, laughing, telling me what a ‘good boy I am’ encouraging me to cum every last drop as I continued to shoot thick globs of my own sticky cum onto my chest and stomach. Some even got onto my face. As I looked back at the video shaking, I shot out the last bit I thought I could manage. My wife started wiping up some of my cum, licking it, telling me she was amazed by how much I had cum. Shaking in my orgasmic high, all I could do was stare at the screen. The cameraman told her to stretch her pussy lips. She struggled to breathe, she had an exhuasted post-orgasm face. Her mouth hung open in shock at what just happened, but her eyes looks drozy. Her hands were shaking and weak as she reached down toward her pussy, sliding her fingers along the actors length, and finally tried to pull her pussy lips apart. As she did, he finally pulled his spent and drained cock out of her. My wife’s tight little pussy was now a gaping wide mess. Her asshole winked again, as thick globbed stream of his milky white cum slowly came out of her, oozing down her asshole before dripping onto the bedsheets. I felt my cock twitch violently and shoot a few more ropes of cum at the sight of it. This caught my wife by surprised as it hit the back of her head, and she laughed. I think she told me that I had managed to shoot some of my cum onto the floor behind me, but my mind was in such a thick fog of exhausted lust, I’m not sure anymore. I was snapped back to reality as she took her panties out of my mouth and proceeded to kiss me. Her mouth was so delicious, I could taste some of my own fluid on her tongue. She put herself over my lap, wiping up some of my cum and rubbing on my cock. She asked if I really liked what I just saw. In my state of drunken lust, I told her it was amazing. She continued, “Well, they actually released this video two days ago online.” I just smiled. I know I probably should have acted surprised, but instead I replied “well, a performance like that should be shared.” She giggled and kissed me passionately. “Well, since then I have gotten quite a few e-mails and texts from other places asking for me to perform. It’s really good money, but I’ll only do it if you’re okay with it.” I just smiled and told her she could under one condition. Any time she does a creampie scene, she has to come straight home afterwards and let me fill her up with my cum. She gave me a the naughtiest smile, and proceeded to take my still-hard cum-covered cock and slide it into her dripping wet pussy. As she started to ride me, she whispered in my ear “Well I guess I’m gonna look forward to two loads every time, huh?” Our sex life just got a lot more interesting.

Several Pentesting Tools and Techniques Used by Information Security Experts

Technology is pulsing all around you, and in the short amount of time that you are hosted in this network that you must try to understand its inner workings. Fortunately or unfortunately, most network and system administrators are persons of habit. All you have to do is listen for long enough, and more often than not it will yield some of those juicy findings, information security experts say.

Regardless of any discussion beforehand, a penetration test has a competitive feel from both sides. Consulting pentesters want their flag, and administrators want their clean bill of health to show that they are resilient to cyber-attack; something akin to a game of flag football. The difference here is that in flag football, both teams are familiar with the tools used to play the game.

It goes without saying that a pentester’s job is to simulate a legitimate threat to effectively determine your organization’s risk, but how can remediation happen without at least some familiarity? Sun Tzu once said, “If you know neither the enemy nor yourself, you will succumb in every battle.”

In order to truly secure our networks, any administrator with cybersecurity duties will need to not only understand what they themselves have, but also step into the shoes of the opposite side.

This article’s intention is to focus on the ‘why’ and not completely the ‘how’. There are countless videos and tutorials out there to explain how to use the tools, and much more information than can be laid out in one blog post. Additionally, I acknowledge that other testers out there may have an alternate opinion on these tools, and which are the most useful. This list is not conclusive. With that being said, let’s get into the list.

Responder

This tool, in the information security expert opinion, makes the absolute top of the list. When an auditor comes in and talks about “least functionality”, this is what comes immediately to mind. If you are a pentester, Responder is likely the first tool you will start running as soon as you get your Linux distro-of-choice connected to the network and kick off the internal penetration test. The tool functions by listening for and poisoning responses from the following protocols:

Link-Local Multicast Name Resolution (LLMNR)

NetBIOS Name Service (NBT-NS)

Web Proxy Auto-Discovery (WPAD)

There is more to Responder, but I will only focus on these three protocols for this article.

NBT-NS is a remnant of the past; a protocol which has been left enabled by Microsoft for legacy/compatibility reasons to allow applications which relied on NetBIOS to operate over TCP/IP networks. LLMNR is a protocol designed similarly to DNS, and relies on multicast and peer-to-peer communications for name resolution. It came from the Vista era, and we all know nothing good came from that time-frame. You probably don’t even use either of these. Attackers know this, and use it to their advantage.

WPAD on the other hand serves a very real and noticeable purpose on the network. Most enterprise networks use a proxy auto-config (PAC) file to control how hosts get out to the Internet, and WPAD makes that relatively easy. The machines broadcast out into the network looking for a WPAD file, and receive the PAC which is given. This is where the poisoning happens.

The information security professionals are aware that most protocols which rely on any form of broadcasting and multicasting are ripe for exploitation.

PowerShell Empire

Before, pentesters typically relied on Command and Control (C2) infrastructure where the agent first had to reside on-disk, which naturally would get uploaded to Virus Total upon public release and be included in the next morning’s antivirus definitions. The time spent evading detection was a seemingly never-ending cat-and-mouse game.

It was as if the collective unconscious of pentesters everywhere came to the realization that the most powerful tool at their disposal was already present on most modern workstations around the world. A framework had to be built, and the Empire team made it so.

The focus on pentesting frameworks and attack tools has undoubtedly shifted towards PowerShell for exploitation and post-exploitation.

It means that some of the security controls you have put in place may be easily bypassed. File-less agents (including malware) can be deployed by PowerShell and exist in memory without ever touching your hard disk or by connecting a USB. A write-up mentioned at the end of this post elaborates much further into this topic. Existing in memory makes antivirus whose core function is scanning disk significantly less effective.

Fortunately, information security researchers say, that the best mitigation here is something you may already have access to , Microsoft’s Applocker. Granted, white listing can take some time to stand up properly and likely requires executive sign-off, but it is the direction endpoint security is heading. This is a good opportunity to get ahead of the curve.

When it comes to mitigation; the execution policy restrictions in PowerShell are trivial to bypass.

Hashcat with Wordlists

This combo right here is an absolute staple. Cracking hashes and recovering passwords is pretty straightforward of a topic at a high level.

Hashcat is a GPU-focused powerhouse of a hash cracker which supports a huge variety of formats, typically used in conjunction with hashes captured by Responder. In addition to Hashcat, a USB hard drive with several gigs of wordlists is a must. On every pentest that the information security analysts have been on, time had to be allocated appropriately to maximize results, and provide the most value to the client.

Sysadmins, think about your baseline policies and configurations. Typically it is best practice to align with an industry standard, such as the infamous DISA STIG, as closely as possible. Baselines such as DISA STIG support numerous operating systems and software, and contain some key configurations to help you prevent against offline password cracking and replay attacks. This includes enforcing NIST recommended password policies, non-default authentication enhancements, and much more. DISA even does the courtesy of providing you with pre-built Group Policy templates that can be imported and custom-tailored to your organization’s needs, which cuts out much of the work of importing the settings.

Web Penetration Testing Tools

It is important to note that a web penetration testing tool is not the same as a vulnerability scanner.

Web-focused tools absolutely have scanning capabilities to them, and focus on the application layer of a website versus the service or protocol level. Granted, vulnerability scanners (Nessus, Nexpose, Retina, etc) do have web application scanning capabilities, though I have observed that it is best to keep the two separate.

Many organizations nowadays build in-house web apps, intranet sites, and reporting systems in the form of web applications. Typically that since the site is internal it does not need to be run through the security code review process, and gets published out for all personnel to see and use.

The surface area of most websites leaves a lot of room for play to find something especially compromising. Some of the major issues are:

Stored Cross-site Scripting (XSS).

SQL Injection.

Authentication bypass.

Directory traversal abuse.

Unrestricted file upload.

If you administer an organization that builds or maintains any internal web applications, think about whether or not that code is being reviewed frequently. Code reuse becomes an issue where source code is imported from unknown origins, and any security flaws or potentially malicious functions come with it. Furthermore, the “Always Be Shipping” methodology which has overtaken software development as of late puts all of the emphasis on getting functional code despite the fact that flaws may exist.

Acquaint yourself with OWASP, whose entire focus is on secure application development. Get familiar with the development team’s Software Development Lifecycle (SDLC) and see if security testing is a part of it. OWASP has some tips to help you make recommendations.

Understand the two methodologies for testing applications, including:

Static Application Security Testing (SAST). The application’s source code is available for analysis.

Dynamic Application Security Testing (DAST). Analyzes the application while in an operational state.

Additionally you will want to take the time to consider your web applications as separate from typical vulnerability scans. Tools (open and closed source) exist out there, including Burp Suite Pro, OWASP Zed Attack Proxy (ZAP), Acunetix, or Trustwave, with scanning functionality that will crawl and simulate attacks against your web applications. Scan your web apps at least quarterly.

Arpspoof and Wireshark

Arpspoof is a tool that allows you to insert yourself between a target and its gateway, and Wireshark allows you to capture packets from an interface for analysis. You redirect the traffic from an arbitrary target, such as an employee’s workstation during a pentest, and snoop on it.

Likely the first theoretical attack presented to those in cybersecurity, the infamous Man-in-the-Middle (MitM) attack is still effective on modern networks, information security researchers said. Considering most of the world still leans on IPv4 for internal networking, and the way that the Address Resolution Protocol (ARP) has been designed, a traditional MitM attack is still quite relevant.

According to information security researcher, many falsely assume that because communications occur inside their own networks, they are safe from being snooped on by an adversary and therefore do not have to take the performance hit of encrypting all communications in their own subnets. Granted, your network is an enclave of sorts from the wild west of the Internet, and an attacker would first have to get into your network to stand between communications.

Now, let’s assume that a workstation is compromised by an attacker in another country using a RAT equipped with tools that allow a MitM to take place. Alternately, consider the insider threat.

The information security experts said that the best tactics of defense are: encrypt your communications. Never assume communications inside your network are safe just because there is a gateway device separating you from the Internet.

Keep your VLAN segments carefully tailored, and protect your network from unauthenticated devices. Implementing a Network Access Control (NAC) system is something you may want to add to your security roadmap in the near future or implementing 802.1X on your network may be a good idea. Shut down those unused ports, and think about sticky MACs if you are on a budget.
