Organisation

I am the lead organizer of Ph0wn CTF. This CTF is dedicated to smart devices. Its first edition was in 2017.

Challenges or CrackMe I designed

I designed a few crackme if you feel like trying:

• Hashdays 2012 Android Challenge: apk blog post blog post 2 solution
• Insomni’hack 2012 CTF: apk solution
