    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 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.
