19-09-2021

  1. Stuck At challenge #03 (Antioch). It seems like i’m close to solve this challenge.
  2. I am very disappointed in myself. I’ve reversed the binary to the death and found every thing to complete challenge #03 but still stuck at docker part.

20-09-2021

  1. Finally challenge #03 is completed. Now going for challenge #04.
  2. I’m planning to read the v8 codebase after I completed the challenge #04.

22-09-2021

  1. Yesterday i completed the challenge #04 and started challenge #05. And there was no electricity at my home whole day.

  2. Today i reversed the challenge #05 whole day and trying to figure out the cipher that’s implemented in this challenge.

23-09-2021

  1. I reversed the challenge #05 to death, figure out what it cipher it was using. Then i replicated the whole cipher in python but while decrypting it outputs random junks. Then i finally get to know there was another way to decrypt the files.

  2. I finally decrypted all the crypted data. But still lot more task to complete this challenge.

24-09-2021

  1. I’m still working at challenge #05 of flareon8. I found 8 bytes of the password still 5 more bytes to complete this challenge. To be honest, this challenge gets worse everytime i found the password byte.

25-09-2021

  1. Finally the challenge #05 is completed. Now starting challenge #06.

28-09-2021

  1. Today i completed the challenge #7. twitter
  2. I am not able to give time for v8 engine for now because i’m to addicted to the flare-on ctf righnow.
  3. After this ctf, i decided to give 4 hour daily for v8 engine, 4 hour for adversary simulation, and 4 hour for reversing and malware analysis or i’ll continue to read v8 engine source code.
