Google CTF nowadays is a pretty large event - or should I say 3 connected events, with the pretty hardcore main CTF being one of them, and Hackceler8 - where speedrunning meets CTFs and game hacking - being the second. The last one, but probably the most popular one is Beginners Quest - a set of CTF challenges tied together with a story (a 001337 spy story in this specific case) and aimed at folks who like challenges, but prefer to take it easy is a stress free (i.e. no scoreboard) environment. Anyway, yesterday I've made an over 4 hour long livestream where I've solved all the challenges from this year's BQ, and here's the recording - enjoy!

Comments:
There are so many CTF challenges I've had to give up on simply because I've lacked some key insight. This session gave some excellent examples of ways to bridge those gaps. Although I do have to admit that some of these particular challenges do seem to be more difficult than I would expect of a "Beginner's Quest".
