The intricacies of a cheat loader
A loader is arguably the most important component of a cheat provider, but what distinguishes one made by a hobbyist from that made by a pay-to-cheat provider? In this blog post, we'll take a look at some of the practices p2c providers use to ensure the security of their product.
Unmapped 003: Wrapping it up
The servermapper looks impressive—DRM protected, no PE on disk, server-controlled delivery. But the core technique is just memory mapping with extra steps. We reversed it by capturing 195 memory writes, extracting the import table, and building our own internal loader.
From BANNED to VIP: Exploiting a CVE
While setting up a popular weapon skins plugin for my Counter-Strike 2 server, I accidentally found a vulnerability in the authentication... and used it.
Unmapped 002: Pattern Recognition
Pattern recognition is the bridge between raw dumps and usable knowledge. By analyzing the structure of memory writes we transform 195 opaque binary blobs into a complete blueprint of the cheats runtime state. This is the work that makes reversing and cracking a servermapped cheats (and or malware) possible.
Unmapped 001: Breaking a Servermapper
Servermappers have been the gold standard for evasive cheat delivery since the early CS:GO days, but most analysis attempts get stuck on PE reconstruction complexities. We bypassed the whole mess with one clever technique and walked away with their cheat in hand.
