Shadow Anticheat

Currently best version yet. Designed with skill and actually works.

Not done with this update still implimenting things but its nearly done.

Basically no more false flags added flight check and nofall as well as better killaura and scaffold checks.

Fixed flight check and spider check now work fixed multiaura and killaura/phase/speed check issues. Made the flight check funny so it now insultes them in chat. .SpoilerTarget">Spoiler: Coming Soon Nofall Check and a Scaffold check

ShadowAC 2.0 – Major Check System Rewrite This update introduces a full rewrite of ShadowAC’s check configuration system, improving accuracy, flexibility, and long-term stability across all server types. While the total number of checks remains 115, nearly every category has been rebalanced, expanded, or refined. High-Level Comparison Area Old Configuration New Configuration Check Structure Basic enable/disable Weighted & categorized False Positive Control Limited Violation decay + weights Detection Depth Single-layer checks Multi-layer detection Packet Handling Minimal Dedicated packet category Ghost Client Detection Not isolated Dedicated system Server Types One-size-fits-all Preset-based tuning Performance Mostly sync Async-capable checks Staff Control Basic alerts GUI, alerts, ghost analysis Movement Checks – Improved Accuracy Old · Basic Fly, Speed, NoFall checks · Limited separation between motion types · Higher chance of false positives on lag New Split Fly checks (basic, advanced, packet-based) Speed checks separated into horizontal, vertical, sprint & sneak Added Elytra acceleration detection Added GroundSpoof & Motion manipulation checks Timer abuse split into game timer & packet timer Better handling of vehicles, boats, ice & liquid movement Result: More precise movement detection with significantly fewer false flags. Combat Checks – Multi-Layer Rewrite Old · Single KillAura & Reach checks · CPS-only AutoClicker detection · Limited aim analysis New KillAura split into 5 independent layers Reach separated into entity & block reach AutoClicker expanded to CPS, pattern & statistical analysis AimAssist now checks smoothness, snap & consistency Added Backtrack detection Improved velocity & knockback handling Result: ShadowAC now detects legit-style combat cheats instead of only blatant ones. Block Checks – Expanded Exploit Coverage Old · Basic Scaffold, Nuker & FastBreak · Limited placement validation New Scaffold split into tower, angle & speed checks Added ImpossiblePlace & AirPlace detection Added BlockReach manipulation Improved XRay with statistical + pattern analysis Added AutoBridge, AutoTool & SpeedMine detection Result: Better coverage for modern client scaffolds and nukers. Player Checks – Quality-of-Life Detection Old · Limited player behavior checks · No packet-level player analysis New Added AutoArmor, AutoEat & InventoryMove Added SkinBlink & PingSpoofer detection Improved ChestStealer reliability Added AutoRespawn & FastThrow checks Result: ShadowAC now catches utility cheats commonly missed by older AntiCheats.

Performance Improvements Async-capable checks Cached player data Reduced main-thread load Better scalability for larger servers We were getting lots of false positives so now we try to limit those but we recommend you disable the spider check in /shadowac gui
