About me

Hi! I am Nikolaos Chalkiadakis and I work in the Application Security field. I have extensive knowledge and work experience in Mobile Security, Android internals, reverse engineering, binary exploitation, and kernel development. I usually post about low-level exploitation with the goal to spread knowledge and to maybe help someone learn something new.
