About.
Hi! I currently do Mobile Security @ Riscure, specifically in the area of mobile payments. In general, I am interested in the following areas:
- Software Engineering (C++, Rust, Java, ...)
- Software Security
- Reverse Engineering
- Malware Analysis
- Game Hacking & Modding
Education
- MSc Computer Security @ Vrije Universiteit
- Thesis: Environmental Fuzzing for Malware Evasion
- BSc Computer Science @ University of Crete
- Thesis: Reverse Engineering Federated Learning Models through Side Channels
Challenges
I enjoy writing CTF challenges as much as I enjoy playing them, so here is a list of some of my reverse engineering challenges that were used in various HackTheBox CTFs:
- [Insane] License Generator (Malware w obfuscated shellcode, C2 traffic, anti-debug, API hash resolving, custom multi layer encryption)
- A university presentation a player made on the challenge: https://slides.com/d/QAYzZig/live
- [Hard] Vessel Cartographer (Malware w anti-debug, API hash resolving, shellcode AES)
- [Medium] Alien Saboteur (Virtual-Machine obfuscated crackme)
- [Easy] Intelligence Service (Control flow obfuscation through indirect calls, return address obfuscation)
