Vex AntiCheat

About
Vex AntiCheat is a high-performance, advanced anti-cheat solution designed to protect your Minecraft server from cheaters, packet manipulators, unauthorized client mods, and in-memory byte manipulation.
Engineered with vector analysis, heuristic checks, and dynamic lag-compensation systems, Vex provides a 99.9% accurate detection rate without compromising your server’s TPS.
✨ Key Features
️ In-Memory & Anti-Reverse Engineering Protection

• Java Agent & Attach Scanner: Detects runtime memory-dumping and bytecode injection tools (Recaf, Bytecode Viewer). Diagnostic tools like Spark, Datadog, and NewRelic are allowlisted.
• JAR Integrity Verification: Automatically verifies SHA-256 class signatures on startup to prevent bytecode tampering and unauthorized hot-reloads.

Client & Mod Validation

• Brand Blacklisting: Blocks over 100 popular hacked clients (Wurst, Meteor, LiquidBounce, Vape, Rise, Sigma, Aristois, etc.) upon login.
• Banned Mod Suppression: Prevents players from joining with unfair advantage mods like Minimaps (Xaero's, JourneyMap), Litematica, ReplayMod, X-Ray, AutoFish, and SeedCracker.
• Companion Mod Verification: Enables strict HMAC secret handshake verification for high-stakes worlds (e.g., ArenaPvP, KitPvP) so only verified client builds can enter.

Smart Detection & Lag Safeguards

• TPS Grace Protection: Automatically scales check tolerances during server lag spikes (below 16 TPS) to prevent false flags for legitimate players.
• Ghost Entity Baiting: Spawns invisible target entities around suspicious players to catch Killaura and Triggerbot users instantly.
• Subnet & Geo Protection: Handles IP changes gracefully across cellular networks and VPNs using subnet matching (IPv4 /16, IPv6 /48) rather than instantly banning dynamic IP shifts.

Built-in Moderation & Punishment System (VexBan)

• Embedded Database: Powered by SQLite with zero external dependencies. Manages temp bans, perm bans, IP bans, mutes, and warning screens out of the box.
• Control Room System (/vex control): Pull suspicious players directly into an isolated inspection environment and release them smoothly when cleared.
