Jumping in with Valgrind for CTFs when time allows (focus blockchain & crypto). Formerly with MadeInFrance and Phreaks 2600.
Some CTF-like platforms i've played on:
- OnlyPwner ~ Full cleared 🔥
- Nodeguardian ~ Hall Of Fame
- CryptoHack ~ Happy to have contributed as the ZKP section co-creator
- RootMe ~ Some web stuff done alongside portswigger courses (& some Game-Hacking in reverse for the lolz)
