Building Acheron: A Decompiler Written in Rust — Part 3
Type recovery: reading pointers, arrays, and structs off address shapes, a type lattice with ranked upgrades, and the SSA canonicalization pass that made struct detection actually work on real code.
Reverse Engineering CoD: Ghosts FastFiles — Part 2: The Format Finally Cracked
With help from primetime43, the inner asset format is finally mapped: pattern scanning, the compLen stride, mptype embedded rawfiles, and 329/331 FFs loading cleanly.
Building Acheron: A Decompiler Written in Rust — Part 2
Structural control flow recovery, condition simplification, post-dominator tree, switch tables, and a visual CFG graph view with pan and zoom.
Building Acheron: A Decompiler Written in Rust — Part 1
Building a x64 decompiler from scratch in Rust. PE loading, instruction decoding, IR lifting, CFG construction, SSA, and pseudo-C generation.
Reverse Engineering CoD: Ghosts PS3 FastFiles
A deep dive into RSA signatures, 7-bit encoding schemes, LZX compression, and memory dumping techniques with RPCS3.
Advanced Cheat Development & Anti-Cheat Bypass
Kernel-level manipulation, custom VMs, DMA, SMM exploits, and the arms race between cheats and anti-cheat systems.
Advanced Malware Development: Injection, Obfuscation & Evasion
Shellcode injection, obfuscation, direct syscall evasion, sandbox bypass, and anti-debug techniques.
Reverse Engineering a Remote Code Execution Vulnerability in MW2
A missing bounds check, a Huffman compression overflow, and how responsible disclosure led to a patch.
Reverse Engineering Abandonware — Sierra's Pharaoh
Patching a CD check in a 1999 city-builder using IDA Pro. One jne → jmp and the disc requirement is gone.
Understanding and Modding Call of Duty FastFiles
Dissecting the .ff format — data structures, compression schemes, and what it takes to build community mods.
Transitioning from C++ to Rust
The good, the challenging, and the ugly of switching languages. Ownership models, lifetimes, and ecosystem maturity.
