Gdbypass

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. |

Key surveys: Kern & Lee 2019 , Almeida et al. 2021 , Zhou & Liu 2022 . | Approach | Strengths | Limitations | |----------|-----------|--------------| | Patch‑based Bypass (e.g., gdb-patch , peda ) | Simple binary patching of known ADB checks | Requires source‑level knowledge; fragile to code changes | | Dynamic Binary Instrumentation (DBI) (e.g., DynamoRIO, PIN) | Transparent instrumentation, can rewrite ADB checks at runtime | High overhead; often detectable via DBI‑specific side‑effects | | Kernel‑Level Interposition (e.g., kdump , LKM hooks) | Can hide ptrace and procfs entries globally | Requires root privileges; kernel signatures can be detected | | Hardware Break‑point Cloaking (e.g., HyperDbg ) | Hides hardware debug registers from the target | Limited number of breakpoints; platform‑specific | | Virtual Machine Introspection (e.g., VMware , QEMU debug APIs) | Complete isolation from target OS | Detectable via hypervisor artifacts; heavy resource usage | | | Stealth against Hybrid Checks | Timing‑based
