安全High Five2023
Server Guard
一层在封包级别拦截漏洞利用和机器人流量的防护。
概览
A guard and anti-bot layer for a High Five server after a wave of movement hacks and duplication attempts.
挑战
Players were exploiting packet-injection movement and probing for dupes. The staff had no visibility and were reacting to Discord reports hours later.
我们的方案
We added server-side validation and rate limiting on high-risk packets, impossible-sequence detection, anti-bot behavior heuristics, and adena-flow anomaly alerts routed to staff - plus fixes for the specific dupe vectors found in an audit.
主要功能
- Packet validation and rate limiting
- Impossible-action detection
- Anti-bot behavior heuristics
- Economy anomaly alerting
- Full admin command auditing
- Regression tests for fixed exploits
