Defensive Rootkits: Engineering Kernel-Level Malware Analysis from Ring 0

This report describes Zynap’s architecture for defeating modern sandbox-evasion: a kernel-mode defensive rootkit combined with a hypervisor layer and real-time persistence/execution engine. It explains how SSDT hooking, code caves and trampolines, KUSER_SHARED_DATA spoofing, registry and filesystem callbacks, injection tracking, pre-deletion dumping, and a protection thread collectively force evasive loaders, RATs, infostealers and ransomware to detonate and preserve full infection-chain evidence for analysis.
