2021-10-02: Google's Beginner Quest 2021 - all tasks solved recording

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!

    23:38 - Task 2: Logic Lock (misc)
    34:27 - Task 3: High Speed Chase (misc)

Five newest or recently updated notes (these are unfinished posts, code snippets, links or commands I find useful but always forget, and other notes that just don't fit on the blog):

The full list of vulnerabilities discovered by me (including collaborative work) can be found here (please note that the list might be out of date).

The Google Application Security / Research site might also contain some of my findings.

EN Coding (selected posts)
EN Tools and libraries
  • PiXieServ is a simplified PXE (network boot) server for Windows and Linux-based OS, created for testing of very small home-made OS. See also the post about it.
  • ExcpHook, a system-wide exception monitor for Windows XP 32-bit. Useful if you're fuzzing something that doesn't like having a debugger attached.
  • Ent is an entropy measuring tool for reverse engineering reconnaissance (see also a post explaining how to use it).
  • HiperDrop is a simple command line process memory dumper for Windows, with a few different work modes.
  • asmloader - this little app executes headerless machine code (compiled assembly code). It's meant to be an aid in learning/teaching and playing with assembly, as well as the right tool when you just need to execute some machine code.
  • NetSock is a simple socket/networking lib/wrapper for C++ I've wrote back in 2003 and update from time to time - I use it for most of my network-enabled projects.
