Cybersecurity made fun . .

The NOVA cybersecurity lab is an interactive beginner friendly way of understanding concepts of cyber attacks on a website. The lab helps users understand how social media platforms (or any website with several users) protects its servers and data. For myself personally I had played for " Einstagram " , the lab has different levels of security that help the user learn to purchase anti-virus software and other ways to protect from data breech. The more coins you accumulate the better your chances are of surviving attacks. For example in one of the games you are required to learn how to code as shown in the image above. Each command will help move your robot to the proper place, this is to help teach us how coding helps in screening firmware and blocking any attacks through the coding of your site. Another example of a lab identifying phishing in emails and calls. Often times emails will have give aways like the email address they are sending to, the name having been misspelled or clear motive to gain personal or financial information. Often times users are susceptible to Cyber attacks like these because they may look identical to a legitimate person/corporation.

TUT Week #7

During the password cracking challenge, I felt it was a way for me to actually put into practice what we learnt about malware and password security. Inputing the number of characters and letting the system do its thing to crack a simple password was surprising. It is weird how easy this has become today. It made me realize how unique passwords are one of the keys to keeping your accounts safe. While completing the social engineering challenge, I realized how spotting fake websites online can be very tricky, but not impossible. I was presented with a google login screen during this challenge and when put side by side with the real thing, it was very easy to spot difference but would be hard otherwise. One primary giveaway however was the url being used for the fake website. It was very evidently shady, which helped me connect back to the staying secure aspect of the cybersecurity topic discussed in module 7. Lastly, while listening to the scam call, I could connect back to the topic of cyberstalking as these scammers slyly try to gather information like ones name, address and banking information that can then be used for financial scams and stalking or fraud.

The unifying threads that knits our society together are solidarity and unity. They serve as a reminder that our unity and acceptance of one another's differences are the foundations of our collective power. We discover the strength to overcome obstacles, cross gaps, and build a society where cooperation, understanding, and compassion are valued above all else via unity. The unbreakable link that binds us all and motivates deeds of generosity, assistance, and encouragement is called solidarity. We find our shared humanity and the promise for a better future when we come together in harmony and solidarity and share a common vision of a world that is better for everyone. Last year, I witnessed the solidarity and unity of youth. Many youth participated and fought for former VP Leni Robredo. I also fought for her including the senators especially Chel Diokno. But, our solidarity isn’t united because there are people spreading fake news or believing in fake news. This made our country suffer in different challenges such as higher rate of inflation. Let’s make it clear that this isn’t the last battle we should fought for. There are numerous ways to support Leni and Chel such as angat buhay program. People should realize that a leader can’t be a leader without his subordinates. Never again to elect a corrupt leader.

Module 7: Security Everywhere - UNSW Campus Security

This week, me and my friends decided it would be a good idea to see if we could ‘break into’ a building at UNSW to study up for our assignments. 

Now Hilmer Building is a building that closes at 6pm, following this the building’s doors are all locked and you can only enter if you are a Materials Science student with the ID card access - which none of us actually were.

So we waited outside until someone left. At 6:08pm, someone was leaving the building so we walked in as they left and headed into the building. Now there are study spaces on level one that do not require any further access but we decided we wanted to go to the higher levels.

So once again, we waited for someone to come downstairs and open the door so that we could sneak up. This took around an hour of waiting before someone came down which allowed us in. 

We were not trying to hide or anything from the security guards but just wanted to see how long it’d take before they would kick us out. It was not until 10:30pm until a security guard asked out to leave.

But even then he didn’t escort us out, just simply asked us to leave and left us. If anything we could’ve packed up and just changed locations.

UNSW Campus Security is not strong enough. Considering that anyone else could’ve made their way into the building and stolen things from laboratories or offices.

Module 7: Lecture 2 Notes

Presentation 1: Bug Bounties

 Where to start Hunting?

Crowd-sourced bug bounty website

Bug crowd

Open to public

Tips to get started

Learn web application principles

Look for wider scope and less competition

Increase number of bugs

Less likelihood of dupes

Stay in scope

Look for assets which have changed recently

Look for publicly disclosed reports

Start at comfortable difficulty

Work towards your skills

Teamwork

 Process of Bug Bounty

Find a suitable program

Review the scope

Find the target via recon

Hit target and find vulnerability

Write a report

Submit the report to the company

 Training resources

Hacker101

Sql injections

Password management

Fuzzing

Eg of fuzzing software - afl

Technique used to look for bugs

Have program and repeatedly feed it input and observe if any bugs are produced

Different types of fuzzers:

Multination-based vs generation based

Aware of input size

The Heartbleed bug

 Presentation 2: Pen Testing

 Pen Testing

Detect vulnerabilities and expose them

Is an authorised simulated cyberattack on a computer system to evaluate risks

Repercussions of an attack on your security system

Why it is important

It allows us to discover vulnerabilities in our system before attackers do

It can test your security controls (firewalls, ips, ids)

Sometimes thinking like an attacker is the best way

Practical uses of pen testing

Gives coverage to companies without getting hacked

Get ahead of the curve

Stages of pen testing

Recon - intelligence is gathered

Planning

Exploitation

Post exploitation

Pen testing tools

Metasploit

Gobuster

Burb

Wireshark - analysing network connections

Nnmap

Kali - package has tools like info gatherinr, reverse engineering, reporting tools, password attacks, maintaining access, exploitation tools, forensics tools, wireless attacks

Burpsuite - most popular software used to test sofware

CTF Websites

Pwnable.com can be used to practise

Read up about the NSW LPI and think about what assets they have and what risks arise from them having been privatised  eg https://en.wikipedia.org/wiki/New_South_Wales_Land_and_Property_Informat

 Shared secret - when the person that needs to be authenticated and the person is authenticated have a secret between them. This can be used to authenticate. Eg. A certain code word

Problem with authentication - if computer has been preloaded with shared secrets and these secrets have been used once, then that's a problem

How can you detect and protect against the man in the middle?

Web of trust (PgP) and PKI. (check out how PGP does authentication using web of trust)

PKI

Links your public key to usually a web domain. It's certified to something that everyone trusts

SSL/TLS

Read Bruce Schneir's paper

Certificate authority ties the key to a domain name. it doesn't tie the key to anyone in the world

 Look up how the TLS handshake works

Look up a simple rsa version

AES & Block Cipher Modes

Crypto Terms

Confusion: When it come to cryptography, confusion mean to obscure the relationship between the key and the ciphertext

Diffusion:  This means that if the plaintext changes slightly then a significant amount of the the cipher text should change and vice versa. 

Avalanche Effect:  Similar to the above. If an input is changed slightly (for example, flipping a single bit), the output changes significantly (e.g., half the output bits flip). 

SP Boxes: An S-boxes (substitution boxes) are typically used to obscure the relationship between the key and the ciphertext (i.e. confusion). A P-box (permutation box) is a method of bit-shuffling which is used to permutate or transpose bits. S-boxes and P-boxes are used to make the relationship between the plaintext and the ciphertext difficult to understand.

Feistal cipher: A Feistel cipher is a symmetric structure used in the construction of block ciphers. Encryption and decryption operations of a Feistel cipher are very similar (sometimes identical). This has the advantage of requiring a small amount of circuitry/code to implement it. 

Block Ciphers: A deterministic algorithm operating of fixed-length groups of bits. The algorithm is an unvarying transformation that is specified by a symmetric key. 

Stream Ciphers: This is a symmetric key cipher where the plaintext is combined with a pseudorandom cipher digit stream. In a stream cipher each plaintext digit is encrypted one at a time with the corresponding digit of the key to produce a digit of the ciphertext. 

Block Cipher Modes

Block cipher mode: How we divide up a file into the specified block size and encrypt them all. 

ECB - Electronic Code Book -

dividing the file up into blocks and encrypting each block separately. A flaw in this method is that the same input code will result in the same output. This makes analysis trivial. 

CBC - Cipher Block Chaining - This solves the problem of ECB by incorporating the past block in each subsequent block. This causes each block to be a result of all the blocks before it. This methods uses a initialisation vector to use as the second input when encrypting the first block. Although this methods solves the issue with ECB it makes encrypting things very slow and no longer parallelisable.

 CTR - Counter Mode - This mode turns the AES block cipher into a pseudo-stream cipher. Instead of encrypting the plain text, it encrypts a NONCE and a counter value. The counter is increased for every subsequent block. This long string of pseudorandom bits is then XORed the actual plaintext. The ciphertext is the result of the XOR operation. 

Activity

Ciphers 1 had repeating blocks so it was using ECB

Cipher 2 was dependant on the length of the input so it was counter mode.

3 ane 4 didn’t have either of the above properties so they were cipher block chaining.

And finally cipher 5 was similar to 1 (also ECB)

Module 7

Process of Writing

This module introduces the Process of Writing, the definitions, parts and types of writing.

Writing is an act or process of one who writes, such as the act or art of forming visible letters or characters specifically handwriting sense, the act or practice of literary or musical composition.

A writing system is a method of visually representing verbal communication, based on a script and a set of rules regulating its use. While both writing and speech are useful in conveying messages, writing differs in also being a reliable form of information storage and transfer.

Prewriting is the first stage of the writing process, typically followed by drafting, revision, editing and publishing.

Drafting, also spelled draughting, also called engineering drawing, graphical representation of structures, machines, and their component parts that communicates the engineering intent of a technical design to the craftsman or worker who makes the product.

Creative Nonfiction Quarter 1 Module 7- Writing

What i have learned in module 7 is all about writing, that writing is a medium of human communication that involve the representation of a language with written symbols. And language are systems of symbols: writing is a system for symbolizing the symbols. Writing system those are alphabets, graphemics, handwriting, idiogram, language and letter. Also the writing as an act of composing text. In this module taught me the process of writing the first is pre-waiting, where in this stage you plan what you are going to write and the next is drafting, in this stage you start with a working thesis and then write your ideas in sentences and paragraphs. Third is revising, in this stage focus on large scale and lastly in process of writing is editing and proofreading, this only focus on a smaller scale. The last topic in this module is about blog that i learned.

Blog Entry # 6: It's me and my country, WAH!

For this module, we were tasked to do a profiling of the ideal and not so ideal leader that we want to have. Reflected in this cute output that we made, the comparison was quite obvious and the message of this infographic is pretty straightforward.

We all have our own ideals and standards in terms of choosing a ruler of our community. But, how were we able to come up with this set of standards and expectations? Why do we have to be particular about it? Why be very critical in choosing who to lead us? Before going through that briefly, it is important to understand our individuality, citizenship and solidarity.

As an individual, we are part of a vast population of humans interacting with one another. Each one of us is placed in an extended social and physical environment. Everyone holds certain basic rights and, also performs fundamental duties towards this expanding world.

In a continuously modernizing and ever changing world, our individual self or our mature versions are all intertwined to not only the physical and societal environment, but we belong to a set of interconnected worlds - our families, our church, our institution, our community, our society, our nation. These worlds affect the individual inasmuch as the individual, through his or her own actions and inactions, affects them.

Talking about our citizenship, this refers to a social construct pertaining to our rights and responsibilities to the society that we live in. Our citizenship is embedded in the concept of people interacting with each other forming a civil society. This interaction entails giving consent of submission to a common authority and giving up certain freedoms while being assured of fundamental rights such as the right to life, liberty, possession, or happiness. This is also a core idea as to why do we have a government system in our country and why do we have to be so critical in choosing them.

It's because we should be assured of our right to live, liberty, and happiness.

Lastly, another concept to understand is solidarity. This refers to an awareness of shared interests, objectives, standards, and sympathies creating a psychological sense of unity. It refers to the ties in a society that bind people together as one. This emphasizes the interdependence between individuals in a society, which allows each of us to feel that they can enhance the lives of others. This concept has been deemed essential to the realization of our rights as individuals.

Going back as to why we should be particular on who to choose as our leader, one thing is for sure: our lives are all interconnected at certain points and the decision of one affects the many.

I have never been open about my political stands but this discussion allowed me to be an active member of my society and help provide education to people on the importance of knowing ourselves, the members of our society, and our country.

How do you manage your classroom?

Managing a classroom that is full of students can be really tough. There would be a lot of students that are running, throwing a piece of paper, some would bully their classmates while some would just really stay from their seat and mind their own business. Managing a classroom is hard IF you don’t have a set of rules or things that could both motivate your student and discipline them at the same time. Your students are also your children, as a teacher, it is also our job to motivate them to learn and study more and be disciplined everyday.

Roblox Modes

Cipher 1: you can spot the repetition of the string “9feedec...” at the start and the end. However, before reaching the required length of the plaintext, you aren’t able to identify any repetitions due to padding when the plaintext is too small. It takes at least 32 before you can see a repeat. Therefore, Cipher 1 is ECB.

Cipher 2: With a small plain-text, the cipher-text is just as small. As you keep adding more data in the plain-text, NONE OF THE PREVIOUS BITS CHANGE. Each letter added translates to two encrypted characters in the output.This therefore alludes to the fact that it is CTR.

This means that for a CTR cipher the stream property yields where increasing the length of the plain-text also increases the size of the cipher-text.

Cipher 3: With a small change in the input, there is an effected half of the output bits, meaning it is by elimination CBC.

Cipher 4: Same reasoning as above, CBC.

Cipher 5: ECB due to repetition again

Module 7: Case Study Notes

Article 1: NSW suggests facial recognition could replace opal cards in ‘not too distant future’

Transport minister, Andrew Constance: board trains using only their faces

Make transport easier and faster

Similar to Amazon’s “Just Walk Out” technology, where shoppers are facially scanned & cameras track items they took & charge their accounts

Opposition: -> pose risk to privacy

Data collected -> tremendous value to owner

Possibilities of future technology are endless:

Identity verification to be integrated with biometric recognition -> enable “next level authorisation & access”

Article 2: Facial recognition is about to end your privacy. How do you feel about that?

Alibaba’s new FlyZoo Hotel in Huangzhou:

Check-in: facial scan

Lift: camera recognises your face & takes you to right floor

Face scan opens you room

Taylor Swift: facial recognition to detect stalkers

New Delhi: facial recognition in finding 3000 missing children

With benefits: scope for abuse -> threat: technology fast outspacing minimal regulation

Government could follow anyone anywhere -> mass surveillance

China: Skynet, can scan its 1.3billion citizens within 1second with accuracy rate 99.8%

Australia’s own mass surveillance program: Identity Matching Services Bill 2018 (IMSB)

Create searchable hub “Capability”, through federal & state photo database (passports, driving licences)

Could be used for more than law enforcements: near real time tracking -> “community safety”

Sydney firm “iOmniscient”: Smart City packages & supplying technology to industries (law & order, oil & gas, healthcare and retail)

Clients in 50 countries

Chinese Army, airports in Indonesia, Korean DMZ & Sydney’s Northwest Rail Link

Turns faces into zeros & ones, break it up into many components (e.g. distance between eyes, nose, face & mouth) -> recognise faces 5x the distance of anyone else in the industry

Article 3: Australians accept government surveillance, for now

Telecommunications & Other Legislation Amendment (Assistance & Access) Act 2018: allows government agencies to access encrypted messages (i.e. those sent over WhatsApp)

2 factors influenced acceptance of surveillance

1. Is surveillance needed?

2. Do I trust the government?

Facial recognition used to identify suspects, often multiple records of images of people who are close match to suspect -> result in high error rate -> risk that innocent people are accused of criminality & wrongdoing

Threat of repurposing:  information collected for one purpose is used for another

i.e. concerns insurance companies could access & use My Health Record -> government amending legislation to prevent this

If surveillance continues to increase -> people may hide themselves

VPNs: virtual private networks -> to prevent government from collecting your online metadata

Article 4:

‘The Capability’ – “to quickly identify a person of interest to help keep the community safe”

2 parts to The Capability:

1. Face Verification Service (FVS): one-to-one image-based match of a person’s photo against a government record (i.e. passport)

2. Face Identification Service (FIS): one-to-many image match of an unknown person (i.e. suspected criminal) against multiple government records to help establish their identity

Research shows ethnic minorities & women are misidentifies at higher rates than rest of population

The Capability doesn’t provide real -time surveillance of public spaces

ACT & Victoria objected The Capability -> violates their local privacy & human rights laws

Use: Room Escape

I and my friends are no stranger to the thrilling experience of escape rooms, we did it together so many times. In my most recent experience, we booked an escape room at Omescape, at the Markham location.

[7501 Woodbine Ave, Unit 7, Markham, ON, L3R 2W1 - 905-695-9556 - https://www.omescape.ca/markham-games ]

The Markham location has 5 different rooms, each with different themes, but we decided to book the “Dark Altar.” I really liked the story as it revolves around stopping an archeology fanatic from completing a dark ritual at a creepy museum, which would somehow give him some sort of godly powers. It was probably inspired by some Hollywood junks. The room had a difficulty of 4/5 and had a very low success rate, which suits us well as we wanted to really challenge ourselves.

Before entering the room, an employee had shown us an instructional video to ensure our safety and protection of the room. Afterwards, we put on blacked-out sunglasses and were lead to the dark room. Once we were all in, the employee left and sealed the door, leaving us to attempt to the stop the ritual and escape the museum. The main reasons I found this particular room to be great was because of: consistency, technologies, and décor. Firstly, all the puzzles remained consistent with the theme of “dark rituals” throughout the room. Secondly, they had used different types of technologies and mechanisms which I haven’t seen before in any other escape room and was very impressed with. For example, we were trapped in a room with no door but had an altar, two coffins, and four skulls. Two team members had to step inside the coffins, which would trigger sensors for lasers to come out of the eyes of 2 skulls on one side of the room. Another set of team members had to use mirrors to redirect the laser beams into the eyes of skulls, which were facing the other side of the room. After successfully doing this, the altar would split into two and uncover a hidden passage behind. Lastly, I thought the escape room’s decorations were very immersive. All the props, decorations, and room schemes really made you feel like you were inside that creepy museum.

Another positive point about the particular location of Omescape we went to is that the main area contains a Yogen Fruz/Preso Tea and Board Game section. I thought it was great that we could grab a snack right after the escape, or failed escape, and hang out playing various board games for however long we wanted.

The only reason critiques I have about Omescape is the noise levels and service. When we were at the end of our escape, we could hear all of the noise in the main area. I felt it made it harder to think about the puzzle solution because the voices of other guests were distracting us. In addition, we felt the after-care service was quite poor. Once we were done the escape, we would be able to take a group picture of memories. However, the employees did not come to the picture area, even after multiple reminders.
