While these methods provide partial coverage, none offers a that simultaneously tackles process, syscall, and hardware‑based ADB checks. 2.3 Gap Analysis | Gap | Why it matters | |-----|----------------| | Cross‑Architecture Support | Modern malware targets ARM64 devices (IoT, smartphones). | | Low Performance Overhead | High‑overhead DBI defeats real‑time debugging scenarios. | | Stealth against Hybrid Checks | Timing‑based heuristics can detect DBI or kernel hooks. | | Ease of Deployment | Analysts often lack root privileges; requiring LKM is impractical. | # Install privileged helper (set‑uid root) sudo cp
