CS2 Player Creates Cheater Ban System
A CS2 player's master's thesis uses mouse and keyboard patterns to ban cheaters permanently.
In brief
A CS2 player's master's thesis uses mouse and keyboard patterns to ban cheaters permanently. A Counter-Strike 2 player developed a system using behavioral biometrics to identify cheaters across accounts, potentially banning them forever instead of just accounts. Originally reported by Dexerto.
CS2 Player's Master's Thesis
A Counter-Strike 2 player developed a system using behavioral biometrics to identify players based on mouse and keyboard use.
“Bans hit accounts, so cheaters just make new ones”
Behavioral Biometrics System
The system compares mouse and keyboard behavior across match demos to determine if two accounts belong to the same person.
Testing Results
Mouse fingerprints correctly identified players 100% of the time across 1,000+ players, while keyboard fingerprints did so 98% of the time.
Identifying Smurfs
The system uncovered previously unknown smurfs by separating known same-player pairings from unrelated accounts.
Correct Pairings
After adding discovered accounts, the system correctly identified all 13 known same-person pairings.
Future Implementation
The system could work with VAC and Trust Factor to ban cheaters permanently, but requires testing at scale and account linking as evidence.
The one thing
A Counter-Strike 2 player developed a system using behavioral biometrics to identify cheaters across accounts, potentially banning them forever instead of just accounts.
