I am extremely fortunate and grateful to have been selected for the NUS Student Sponsorship Program to attend the upcoming @offbyoneconf @starlabs_sg !
If you're attending the conference and would like to meet, I would love to do so!
(p.s. it's not too late to get tickets ;))

Patches for some of the bugs that @junr0n, @elma_ios and I found during SpiritCyber 2025 have finally been released!
(I just found out that the CVEs has been released too oops👀)
It was a joy working with @TPLINK and Team.

I wrote about how LLMs broke CTF competitions over on Mastodon.

Unfortunately, I didn't finish this year's Flare-On due to poor time management but I wrote a writeup on how I solved challenge 8 purely with WinDbg using Time Travel Debugging and LinQ queries.
Check it out :)

Have you ever wondered what happens if we break compiler conventions? I was able to obfuscate the control flow of a program and hide code by modifying non-volatile registers to modify the behavior of library code.

I was able to come up with a proof-of-concept executable where I was able to obfuscate the program's control flow by modifying non-volatile registers such that we can modify the behavior of library code to make jumps to blocks of code that is not visible to the disassembler.
I was messing around with symbol resolution in ELF and came up with an obfuscation technique on abusing symbol resolution in ELF programs that is able to trick tools (i.e. Ghidra, IDA, GDB) into showing the wrong library function calls.

I also wrote a CTF challenge for @r3kapig that uses this obfuscation technique where participants have to either write a debugger script or parse .rela.plt to identify and fix the function calls.
