About me

Hi! I am Nikolaos Chalkiadakis (aka “nikosChalk” or “Fane”) and I am a Security Analyst @ Riscure! I am currently active in the mobile security and mobile payments landscapes. I have extended knowledge in Android internals, mobile pentesting, reverse engineering (static & dynamic analysis), binary exploitation, and kernel development. As you can probably already tell, I really enjoy low-level stuff.
