Binary deobfuscation, unpacking, and string recovery for protected native binaries (ELF, PE, Mach-O). Use this when encountering obfuscated, packed, or virtualized code — including VMProtect, Themida, Code Virtualizer, Arxan/Irdeto, custom protectors, or unknown obfuscation. Triggers: any mention of 'deobfuscation', 'obfuscated', 'packed binary', 'string encryption', 'code virtualization', 'anti-tamper', 'VMProtect', 'VMP', 'Themida', 'obfuscator', 'unpacking', encrypted sections, import obfuscation, or dynamic API resolution.
VMProtect deobfuscation and unpacking for native binaries (ELF, PE, Mach-O). Use this when encountering VMProtect-packed binaries, virtualized code, mutated functions, obfuscated strings, or anti-tamper protections. Triggers: any mention of 'VMProtect', 'VMP', '.vmp0/.vmp1 sections', virtualized code with handler dispatch loops, excessive push/pop/jmp chains, or binaries with characteristic VMP section names. Covers detection heuristics, string deobfuscation, IAT reconstruction, devirtualization strategies, and anti-debug bypass.
Unreal Engine 5 internal structures and memory layouts for reverse engineering. Covers UObject hierarchy, FNamePool, FUObjectArray, FProperty system, UFunction, FField, GWorld, Large World Coordinates, and key UE5 global arrays. Use this when analyzing UE5 game binaries.
Expertise in reverse engineering binaries using radare2 (r2). Use this to analyze executables (ELF, PE, Mach-O), decompile code, disassemble code, find functions, extract exports/imports, extract strings, patch binaries, and debug programs.
Use this skill for dynamic binary analysis combining radare2 static analysis with Frida's runtime instrumentation. Triggers include any mention of r2frida, dynamic instrumentation, runtime analysis, memory hooking, function tracing,n runtime manipulation, live debugging, or combining radare2 with Frida. Also use when the user needs to trace function calls, hook native functions, dump memory at runtime, modify return values, search memory patterns in running processes, or analyze obfuscated mobile applications.
Use this skill whenever writing, debugging, or reviewing Frida instrumentation scripts targeting iOS ARM64 or Android. Triggers include: any mention of 'Frida', 'dynamic instrumentation', 'hooking', 'Interceptor', 'Stalker', 'ObjC bridge', 'Java bridge', 'frida-server', 'frida-gadget', 'NativeFunction', or requests to hook/trace/patch native or managed functions at runtime. Also use when bypassing SSL pinning, root detection, anti-cheat systems, or Frida self-detection. Apply for both JavaScript and TypeScript agents targeting frida-tools 14+ and Frida 17.x. Do NOT use for static binary analysis (use radare2/Ghidra skills instead), build-time patching, or non-Frida instrumentation frameworks.
