## What’s a Cyber Forensic Investigator?

Master post - part 1 • part 2

You must have heard bout forensics yk investigating bout dead people who might have been killed and all

You must have seen shows on those topics too.Cyber forensic investigator is just of same kind but investigating through all types of modern gadgets.

Catching hackers and all but cooler

### The Money Talk: How Much Do They Make?

- **Cash Money**: Expect to rake in about $60k to $120k a year. If you are very much experienced and skilled then you can expect about 150k+ a year.(obv different countries and companies may have different wages)

### Companies That Want You

- **Tech Titans**: Google, Amazon, Facebook—they all have requirement for such heroes

- **Gov Jobs**: FBI, CIA—basically every spy agency wants you.

- **Cybersecurity Firms**: CrowdStrike, McAfee—so every gateway you go you gonna have opportunities everywhere.

### What Other Forensic Investigators Are There?

- **Forensic Pathologists**: Real-life detectives who figure out how someone died. Less tech, more science.

- **DNA Analysts**: The ones matching DNA samples

- **Forensic Accountants**: Following the money to catch fraudsters and scammers

- **Toxicologists**: Poison experts, figuring out if someone’s been covertly poisoned. (Yeaa yk snow white story)

### What’s the Work Environment Like?

- **The Lab**: Imagine a room filled with more screens than your gaming setup. Gadgets galore, maybe even a Red Bull or two

- **On the Move**: Sometimes you’re out in the field, collecting evidence. Think of it like collecting rare items in a game.

- **Remote Vibes**: You could be solving cybercrimes from your bed in your PJs .

### How Long Does It Take to Become One?

- **Time Investment**: About 4 years for a bachelor’s, and then 1-2 more years for a master’s if you’re going all-in. So, 5-6 years total. But hey, good things take time, right?

### What Do You Study?

- **Cybersecurity/Computer Science**: Your main jams. Think of them as the ultimate cheat codes for this career.

- **Digital Forensics**: Specialized courses where you learn to be a digital ninja.

- **Law and Ethics**: Learning how to catch the bad guys without breaking the law yourself. (You yourself don't want to be troubled obviously)

### Subjects You Need to Get Into It

- **Math**: Yep, but not the boring kind—more like coding and algorithms.

- **Computer Science**: Your go-to for everything techy.

- **Optional Nerd Points**: Chemistry/Physics if you’re into hardware forensics or just want to flex those brain muscles.

### Work Hours: What to Expect?

- **9 to 5-ish**: Standard hours if you’re working for a company, but expect some late nights or weekend shifts when big cases pop up.

- **On-Call Madness**: Sometimes you’re on-call like a digital firefighter. Cyber-attack at 3 AM? Time to suit up (or log in) and handle it.

- **Flexible/Remote**: If you’re lucky, you can work from home. Just remember, no solving crimes in your underwear during Zoom meetings!

### Interview with a Cyber Forensic Investigator

**Interviewer**: What’s a day in the life of a cyber forensic investigator?

**Cyber Sleuth**: Imagine rolling out of bed, grabbing your coffee, and diving into cases. I’m talking analyzing hard drives, sifting through emails, or tracking down cyberattack origins. Some days it’s all data, other days I’m working with law enforcement or testifying in court. Never a dull moment!

**Interviewer**: What’s the coolest case you’ve worked on?

**Cyber Sleuth**: Helping bust a phishing ring that was scamming millions. Tracked their digital footprints, caught the culprits, and recovered their loot. Felt like a total legend.

**Interviewer**: Ever seen some dark stuff, like murders?

*Cyber Sleuth**: Yeah, I’ve stumbled across some pretty grim stuff. It’s not all memes and malware—sometimes it’s serious business. But catching those bad guys makes it all worth it.

**Interviewer**: Have you ever been on the dark web?

**Cyber Sleuth**: Oh, for sure. It’s like the sketchy underbelly of the internet. Lots of shady deals. I go there when I need to, but it’s not a fun hangout spot.

**Interviewer**: How dark can a case get?

**Cyber Sleuth**: It can get really intense. I’ve worked on cases involving human trafficking and other serious crimes. It’s tough, but making a difference makes it worth it.

**Interviewer**: Any advice for someone who wants to get into this field?

**Cyber Sleuth**: Stay curious and keep learning. Tech evolves fast, so you’ve gotta keep up. And don’t be afraid to dig deep—sometimes the answers are buried in tons of data, but finding them is like hitting gold.

So if you’re into tech and have subjects like mathematics , chemistry and physics then you are all set to start your journey.i have seen ppl running for a common a job and all and they are not even specified about what they want. So just research and find out what you want.

Oof definitely going to have to completely re-write most of the oberyn&daemon investigation pieces for this next APWH chapter because i've been working on it tonight and it feels extremely disjointed rip my sanity

[missrandomdreamer]

Sometimes I wonder if there is something wrong with my brain because I cannot wrap my head around like math and science things. I am taking a class on digital curation and my brain just kind of looks at the words about coding and the articles we read and im just like uuhhhhhh

what dis?

How dis work?

What are these words?

I dont know if I just have issues concentrating or processing things like that or what

when it comes to history and arts im fine but when its like that type of science and especially math my brain is just

white noise @.@

I made an informative, yet very quick, video on Tiktok that it's basic message is that you need to destroy the computer in order to get rid of data and they're all like "I don't wanna hear it" or "you stink" like MF they'll find shit ok. Even in ram they can find shit if the computer they got just turned off seconds ago I'm telling you I used EnCase in college deleting information doesn't do SHIT you either destroy it or you buy a very expensive degaussing machine to give your computer a lobotomy either way that computer ain't gonna work anymore

[reinanova]

do NOT leave an electronic paper trail!!!!

do NOT put it in writing on your electronics—that means no texts, no emails, no snapchat’s, no dms! all of that stuff is findable even if you delete it

the internet is forever, never forget

Anyway American trans friends, now's the time to put "be gay do crime" into practice and the first step is to get onto secure communication channels so you're not discussing details of what you're doing and how on the public internet.

Advantages of Video Enhancement in Lansing and Saginaw

A picture tells a thousand words and can be used effectively. This statement has been revised now thanks to the advent of new technologies. Indeed! The moving picture or video has entered the world with a vengeance by capturing reality perfectly. Unfortunately, law enforcement authorities are often baffled by the quality of videos and unable to discover the truth. Improving the quality of such images frame by frame or simply concentrating on a single frame can yield many results regarding the investigation. Using the services of experts for video enhancement in Lansing and Saginaw is commonplace, therefore.

It is a common notion that investigators can discover hard facts by simply taking one look at the available video footage. Unfortunately, there is little truth in it. On the contrary, the recovered video footage from a device installed at a crime scene is usually insufficient. First, law enforcement officials must be aware of the devices capable of capturing a video, thus revealing the truth. Some of the devices that may contain hidden facts, making the video footage an essential tool for investigation, include the following:-

· Mobile or smartphones · Laptops · Smart Watches · Tabs · Nanny cams · Dashcams · Body cams

The videos retrieved from the devices mentioned above must be checked and analyzed to yield the required information. Enhancement of the videos is usually done to improve their quality and emphasize particular features that may be important as evidence. The reasons to use skilled professionals for video enhancement are as follows:-

· Proper Storage- Retrieving the required footage from the right device is necessary, but one must be equally concerned about retrieving the data perfectly. Storage is another aspect that must be done just right to recover vital video information.

· Adjustments- The first look at the video will expose the weaker points that hide the facts. The professional must take pains to adjust the brightness of the moving images. The contrast and gamma need proper adjustment to improve the clarity of the videos as well

· Speed - The playback speed of the video needs to be perfect to retrieve the right information. Professionals can slow or enhance the speed of the paying video according to the requirement.

· File Conversion- Different types of devices capture the video footage. Therefore, The retrieved images are likely to be difficult to extract or read. Forensic experts or video enhancers can effectively convert the file formats into one that may be accessed easily, with its information being easy to read.

· Forgery Detection- There are many instances of forged videos being submitted to the court during an ongoing trial. It is the responsibility of the video enhancer or forensic expert to look for inconsistencies in videos that seem fake.

Recreating a crime or any offense is easy using a skilled computer forensic investigator in Chicago and Lansing.

so there's definitely an ai database linking all the info known about people including the other people they know, their most common locations on a map, and where they're likely to show up next, right. like there's absolutely predictive ai going beyond advertisements trying to get you to go to some store and just skipping to knowing you'll be at the communist party meeting in the basement of the unitarian church on 78th because you hang out with the people who usually go to those meetings and you hang out at the leftist second-hand bookstore/coffeeshop and you follow communist former-twitter accounts and you live within 6 city blocks of the unitarian church which holds communist party meetings in its basement and you made jokes specifically about how funny it is the communists would meet in a church that your al*xa picked up & alerted on the triggerwords and your work schedule just changed to allow you to meet up. and the authority figures who need to know that have that ai database.

i don't mean 'you' because you're not important but i mean, it exists.

Superlensing Without a Superlens: Microscopes Boosted Beyond Limits - Technology Org

Superlensing Without a Superlens: Microscopes Boosted Beyond Limits - Technology Org

New superlensing technique could be used in medical imaging and advanced manufacturing.

Physicists at the University of Sydney have shown a new pathway to achieve superlensing with minimal losses, breaking through the diffraction limit by a factor of nearly four times. Their trick? Remove the superlens altogether.

Ever since Antonie van Leeuwenhoek discovered the world of bacteria through a microscope in the late seventeenth century, humans have tried to look deeper into the world of the infinitesimally small.

There are, however, physical limits to how closely we can examine an object using traditional optical methods. This is known as the ‘diffraction limit’ and is determined by the fact that light manifests as a wave. It means a focused image can never be smaller than half the wavelength of light used to observe an object.

Attempts to break this limit with “super lenses” have all hit the hurdle of extreme visual losses, making the lenses opaque. Now physicists at the University of Sydney have shown a new pathway to achieve superlensing with minimal losses, breaking through the diffraction limit by a factor of nearly four times. The key to their success was to remove the super lens altogether.

The research is published today in Nature Communications.

The work on superlensing should allow scientists to further improve super-resolution microscopy, the researchers say. It could advance imaging in fields as varied as cancer diagnostics, medical imaging, or archaeology and forensics.

Lead author of the research, Dr Alessandro Tuniz from the School of Physics and University of Sydney Nano Institute, said: “We have now developed a practical way to implement superlensing, without a super lens.

“To do this, we placed our light probe far away from the object and collected both high- and low-resolution information. By measuring further away, the probe doesn’t interfere with the high-resolution data, a feature of previous methods.”

Previous attempts have tried to make super lenses using novel materials. However, most materials absorb too much light to make the super lens useful.

Scientists used a new superlens technique to view an object just 0.15 millimetres wide using a virtual post-observation technique. The object ‘THZ’ (representing the ‘terahertz’ frequency of light used) is displayed with initial optical measurement (top right); after normal lensing (bottom left); and after superlensing (bottom right).

Dr Tuniz said: “We overcome this by performing the superlens operation as a post-processing step on a computer, after the measurement itself. This produces a ‘truthful’ image of the object through the selective amplification of evanescent, or vanishing, light waves.

Co-author, Associate Professor Boris Kuhlmey, also from the School of Physics and Sydney Nano, said: “Our method could be applied to determine moisture content in leaves with greater resolution, or be useful in advanced microfabrication techniques, such as non-destructive assessment of microchip integrity.

“And the method could even be used to reveal hidden layers in artwork, perhaps proving useful in uncovering art forgery or hidden works.”

Typically, superlensing attempts have tried to home in closely on the high-resolution information. That is because this useful data decays exponentially with distance and is quickly overwhelmed by low-resolution data, which doesn’t decay so quickly. However, moving the probe so close to an object distorts the image.

“By moving our probe further away we can maintain the integrity of the high-resolution information and use a post-observation technique to filter out the low-resolution data,” Associate Professor Kuhlmey said.

The research was done using light at terahertz frequency at millimetre wavelength, in the region of the spectrum between visible and microwave.

Associate Professor Kuhlmey said: “This is a very difficult frequency range to work with, but a very interesting one, because at this range we could obtain important information about biological samples, such as protein structure, hydration dynamics, or for use in cancer imaging.”

Dr Tuniz said: “This technique is a first step in allowing high-resolution images while staying at a safe distance from the object without distorting what you see.

“Our technique could be used at other frequency ranges. We expect anyone performing high-resolution optical microscopy will find this technique of interest.”
