3 sets of Cybersecurity challenges & answers (CTF) to learn from

Hello everyone,

I've been streaming Security topics on my Twitch Stream and I've discovered that capture the flag competitions (CTF) is a great way to learn about encryption, forensics, web exploits, and more. But what are CTF's you might be asking?

In the simplest terms, you hack into a resource and find the flag. Which may look at xxxFlag{XXX}. Flags are placed in various locations such as a file, database, source code, or many other types.

The official definition looks something like:

A capture the flag (CTF) contest is a special kind of cybersecurity competition designed to challenge its participants to solve computer security problems and/or capture and defend computer systems. Typically, these competitions are team-based and attract a diverse range of participants, including students, enthusiasts, and professionals. A CTF competition may take a few short hours, an entire day, or even multiple days.

Below I've listed 3 videos that I made for the hacking CTF site known as CTFLearn.


Challenge 1 - CTFLearn - We successfully answered the following challenges: Basic Injection, Forensics 101, Character Encoding, Simple Programming

(Video 7 mins)

Challenge 2 - CTFLearn - We successfully answered the following challenges: Taking LS, Where Can My Robot Go?, Binwalk, Practice Flag, Reversal of fortune, Hextroadinary, Wikipedia

Video (8 mins)

Challenge 3 - CTFLearn - We successfully answered the following challenges: Base 2 2 the 6, POST Practice, Basic Android RE 1, BruXOR, QR code

Video (7 mins)

Conclusion

Stay tuned for future streams as we typically stream security on Sat/Sun at 10 AM PST or you can watch the condensed version by subscribing to my YouTube.
