19/01/2015 | Code, CTF, Forensics, Malware | by Thice

More than two years ago I worked on meaningful MD5 collisions, especially creating executables files, but I never finished my write up about this until now (hurray for having a sabbatical 😉 ). The idea behind this project was to create multiple executables with the same MD5, but with different behavior. I ended up creating […]

11/12/2014 | Forensics, Hardware | by Thice

08/10/2011 | Code, Forensics | by Thice

I recently ran into the issue that my new photo-camera (Samsung WB650) somehow decided to erase all the data of my SD card. Since the SD card was filled with a lot of photos and video files I decided to image the SD card and to try to recover my files. The photo files all […]
