Used for Android APK reverse engineering in CLI environment. Suitable for APK unpacking, Java decompilation, smali modification, repackaging, Frida dynamic Hook, and switching to so/native analysis on demand. Prioritize using locally installed jadx, apktool, frida, adb, ida-reverse, radare2.
Reverse engineers malicious Android APK files using JADX decompiler to analyze Java/Kotlin source code, identify malicious functionality including data theft, C2 communication, privilege escalation, and overlay attacks. Examines manifest permissions, receivers, services, and native libraries. Activates for requests involving Android malware analysis, APK reverse engineering, mobile malware investigation, or Android threat analysis.
Decompile Android APK, XAPK, JAR, and AAR files using jadx or Fernflower/Vineflower. Reverse engineer Android apps, extract HTTP API endpoints (Retrofit, OkHttp, Volley), and trace call flows from UI to network layer. Use when the user wants to decompile, analyze, or reverse engineer Android packages, find API endpoints, or follow call flows. 中文触发词：反编译APK、安卓逆向、提取API、分析安卓应用、反编译安卓、逆向工程、追踪调用链、提取接口
Perform static analysis of Android APK malware samples using apktool for decompilation, jadx for Java source recovery, and androguard for permission analysis, manifest inspection, and suspicious API call detection.
Expert-level reverse engineering and binary debugging skill. Use this skill whenever the user wants to analyze, decompile, disassemble, or debug binaries, executables, APKs, iOS apps, firmware, or obfuscated code. Triggers for: static analysis, dynamic analysis, malware analysis, exploit development, CTF challenges, binary patching, anti-debug bypass, protocol reversing, memory forensics, hooking, frida scripting, GDB/LLDB debugging, radare2, Ghidra, jadx, apktool, strings analysis, symbol resolution, or any request involving "reverse engineer", "RE", "decompile", "disassemble", "patch binary", "debug crash", "analyze malware", "bypass protection", "hook function", "intercept traffic", "find vulnerability", or examining unknown file formats. Always load this skill for CTF pwn/rev challenges, app security assessments, and firmware analysis.
End-to-end Android APK red-team pipeline — automated APK acquisition (Play Store + apkpure + apkmirror fallback), jadx decompilation, secret/URL/JWT/Firebase grep, pinned-cert extraction, exported-component enumeration, Frida runtime instrumentation templates, intent-injection probes. Built from an authorized external red-team engagement where 7 APKs were pulled manually, 4 download attempts truncated, and a hardcoded JWT + 30 internal API endpoints were recovered from one of the apps. Use when target has a mobile app catalogue (Play Store developer page), when you find an APK URL hosted on a web server, or when post-recon mentions "mobile app" in scope.
