Anticheat Update Tracking

few years ago when I was into reverse engineering and binary analysis (and game modding), I did a lot of research into anticheats work. I was curious about tracking their updates, since that would allow me to: - Know when a new version is released - Understand what changes were made - Use older versions for research purposes So I ended up researching different ways on how to track updates of various anticheats.

By knowing that the encrypted module has a high entropy, which means that it's very unlikely that there will be patterns in the data, we can simply search for at least 8 bytes of zero padding which is always present after the size. I worked on this project a few years ago, even gave a talk at a local meetup about the architecture, but never got around to publish a blog post about the internals. This anticheat requires you to have an account, and last time I checked their download page had a CAPTCHA, making it a little bit more inconvenient to track updates.
