Playing with LLVM based control flow flattening (heavily inspired by @rh0main's @open_obfuscator), super basic initial demo is running github.com/samrussell/obf… Writeup will come later (and @vector35 based attacks!)

Congratulation to Nuno Silva & Korami for solving the challenge. Scoreboard updated: obfuscator.re/challenges/


Congratulation to @nneonneo for the resolution of the challenge (along with the first place of the @sstic challenge) !


Congratulations to @0xabc0 who is the fourth person to resolve the challenge!

Nice and fun challenge from @open_obfuscator! Finally managed it to solve it. Definitely give it try if you are into android rasp+protection stuff

And there is a third winner who finished the challenge! Well done to Alemdar. So far, the challenge has been (uniquely) downloaded 533 times and 3 people managed to break it. There are still some aspects that have not been uncovered so do not hesitate to give it a try ;)

Congratulations to @Dauntless who is the second participant to find the login/password! His technique is completely different from @HodelAaron so it's great to see the different approachs.

Congratulation to @HodelAaron for being the first one to find the correct login/password in about 2 days! It took far less time than expected and he exploited in a talented way, the weaknesses left in the protection of the application.

It seems that we might already have a winner for the challenge :)

Actually you need to generate a GitHub token to access the public packages

It looks like the Maven package integration with GitHub is broken. I'll look for a fix.
