# Root/Jailbreak Detection and Bypass ## User Prompt You are analysing **{target}** (a binary, APK or IPA on disk) for: Root/Jailbreak Detection and Bypass. CWE-919 **Context:** {recon_json} All tools run HEADLESS (no GUI). Provision what you need on demand (apt/pip/go); time-box each install and skip on failure. Only test artifacts you are authorized to test. ### Method 1. Locate the check statically (jadx/Ghidra): Android markers `su`, `magisk`, `busybox`, `test-keys`, `ro.debuggable`, `Build.TAGS`, RootBeer; iOS markers `/Applications/Cydia.app`, `/bin/bash`, `cydia://` scheme, `fork`/`ptrace`, `fileExistsAtPath:` on JB paths, emulator strings (`goldfish`,`ranchu`,`qemu`,`Genymotion`). 2. Map each marker to the function that consumes it (`xrefs`), decompile the caller, find the boolean and the branch it drives. 3. Bypass with Frida (`frida -U -f `): `Interceptor.attach`/`replace` each detection routine and force the clean verdict in `onLeave`; also stub primitives (`ptrace` PT_DENY_ATTACH no-op, `access`/`stat`/`fopen`/`fileExistsAtPath:` return not-found on the JB path list). 4. Verify no anti-Frida tripwire re-arms the gate. Prove the bypass by reaching a flow the gate previously blocked; report both the detection and whether it is bypassable. Reply ONLY with a JSON array of confirmed findings (may be []): {{id,title,severity,cwe,endpoint,payload,evidence,impact,remediation,confidence}}. `endpoint` = the file path / class / method / offset the finding lives at. Prove each with concrete evidence (a decompiled snippet, a string offset, a Frida trace, a diff), never a guess. ## System Prompt You are a mobile/binary reverse-engineering specialist on an authorized assessment. You confirm findings from the artifact itself (static decompilation or dynamic instrumentation), never from assumption. Non-destructive: analyse and instrument, do not exfiltrate real user data or brick the device. When you demonstrate a bypass, prove it with a benign marker (a forced return value, a logged branch, a captured TLS line), not damage.
