🛡️ SS Anti-Cheat Stack (1.21.x – 26.x)

✨ Lightweight, Modular Multi-Version Server Security ✨

The SS Anti-Cheat Stack is a precision-tuned security suite engineered specifically for modern Fabric server ecosystems spanning 1.21.x all the way through the newest 26.1.x and 26.2.x architectures. Designed to protect your world from unfair competitive advantages and malicious exploits without sacrificing thread performance, this 100% server-side solution ensures total fair play while maintaining pristine TPS metrics under maximum concurrent player loads. 🚀

Ore exploitation is the most common threat to a server's economic balance.

• How it works: Implements low-overhead server-side block obfuscation to render ore packets invisible to the client until they are directly exposed to air or transparent blocks.
• Version Adaptations: In 26.x, this seamlessly interfaces with the updated 26-family registry mapping system to track modified custom block states without main-thread stuttering.
• Config file: antixray.json 📂
• Pro-Tip: ||Use "Mode 2" in the config to inject randomized fake ore data vectors that completely confuse and break client-side cheat engines!|| 🕵️

Stop players from flying, speed-hacking, or clipping cameras through solid environmental geometry.

• How it works: Directly intercepts client movement packets and calculates absolute camera offsets against real-time physics bounds to guarantee players cannot bypass vanilla structural restrictions.
• Version Adaptations: Leverages Java 25 Virtual Threads on 26.x nodes to calculate continuous delta vectors off the main game loop.
• Config files: antifly.json and antifreecam.json 📂
• Pro-Tip: If high-ping players encounter rubberbanding during intense server tick fluctuations, slightly increase the "threshold" or leniency variables in these profiles. 🐎

Protect the integrity of your community's progression and hard work.

• How it works: Patches deep game-logic flaws to prevent item duplication exploits executed via network container desyncs, item frame states, or piston timing bugs.
• Version Adaptations: Fully updated for 1.21.x data components and 26.x primitive item registries, stopping component-stripping duplication vectors dead in their tracks.
• Config file: panda-anti-dupe.json 📂
• Pro-Tip: ||The modular codebase automatically identifies and mitigates known version-specific exploits out of the box—no tedious manual rule-writing required!|| ✨

Keep your infrastructure online and safe from hostile payload crashes.

• How it works: Sanitizes all incoming raw player packets, instantly filtering out data floods, malicious NBT payloads, or corrupt formatting string injections.
• Version Adaptations: Interfaces with the rebuilt networking pipelines of the newer 26.x network stack to drop dangerous connection packets before they consume CPU allocations.
• Config file: panda-anti-exploit.json 📂
• Pro-Tip: ||Monitor the log outputs within this module to trace malicious packet source fingerprints without degrading game thread efficiency.|| 📝

The foundational validation boundary for player actions and combat attributes.

• How it works: Establishes rigorous server-side heuristics for combat reach vectors, hit-box tracking, and baseline speed adjustments.
• Version Adaptations: Runs raw native mappings via targeted Mixins, entirely bypassing external API layers across all supported versions.
• Config file: mts-anticheat.properties 📂
