Hi there, my name is Thomas Rinsma. This page serves as a bit of an overview of me and my online presence.
Some things I like in no particular order are: neat algorithms, beautifully ugly hacks, automating things, deconstructing things, well-structured information, programming, reverse-engineering, lists.
I am currently working as a Senior Security Analyst at Riscure.
Things I made or projects I’m working on:
- My recently-revived hobby project: Dromaius, a GameBoy emulator/debugger.
- DROP, an IDA Pro plugin for interactive deobfuscation.
- A modern C++ game-engine with recursive portal rendering code, blog post (c. 2013)
I wrote a few things for/during my studies:
- A small paper on the recognition of static libraries in binaries.
- My master’s thesis on interactive deobfuscation of opaque predicates.
- My bachelor’s thesis on University Card (RFID) cloning (c. 2015).
I’m just bragging now, but hey, it’s my website.
- As of November 2018, I am an OSCP :)
- I co-hosted a side-channel analysis workshop at the Croatia summerschool on real-world crypto and privacy.
- I am a casual bug bounty hunter, check me out in the OV-Chipkaart Hall-of-Fame ;).
- A PC-speaker beep shellcode I wrote when I was 16 is listed in the Vault 7: CIA Hacking Tools WikiLeaks dump.
