Claude directly reads and interprets disassembled code, identifies patterns, reconstructs logic, and helps navigate complex binaries using RE tool output.\n\n---\n\n## Activation Triggers\n\nThis skill activates when the user asks about:\n- Analyzing an ELF, PE (exe/dll), Mach-O, or raw binary\n- Interpreting x86, x64, ARM, MIPS, or RISC-V assembly code\n- Reverse engineering firmware from embedded/IoT devices\n- Reverse engineering a network protocol\n- Using Ghidra, IDA Pro, radare2, or Binary Ninja output\n- Identifying what a binary or function does\n- Finding vulnerabilities in disassembly\n- CTF binary challenges (pwn, reversing categories)\n- Anti-debugging or anti-analysis technique identification\n- Unpacking or deobfuscating binaries\n\n---\n\n## Prerequisites\n\n```bash\npip install capstone pyelftools pefile lief\n```\n\n**Recommended RE tools:**\n- `Ghidra` — NSA open-source RE framework (free)\n- `radare2` / `Cutter` — Open-source RE framework\n- `Binary Ninja` — Commercial RE platform with scripting\n- `IDA Pro / Free` — Industry standard disassembler\n- `GDB + GEF/PEDA/pwndbg` — Dynamic debugging\n- `Binwalk` — Firmware extraction and analysis\n- `strings, file, objdump, readelf` — Standard Linux utilities\n\n---\n\n## Core Capabilities\n\n### 1. Initial Binary Triage\n\n**When the user provides a binary or asks what a file is:**\n\nRun these commands and share output with Claude for analysis:\n\n```bash\n# File type identification\nfile suspicious_binary\n\n# Strings extraction (often reveals C2, keys, paths)\nstrings -a suspicious_binary | grep -E \"(http|/etc|password|key|secret|flag)\"\n\n# ELF analysis\nreadelf -a suspicious_binary\nobjdump -d suspicious_binary | head -100\n\n# PE analysis\npython scripts/binary_analyzer.py --file malware.exe --strings --imports\n\n# Entropy analysis (high entropy = packed/encrypted)\npython scripts/binary_analyzer.py --file binary --entropy\n```\n\n**Binary Triage Checklist:**\n```\n[ ] File type and format (magic bytes): ELF / PE / Mach-O / raw\n[ ] Target architecture: x86 / x64 / ARM32 / ARM64 / MIPS / RISC-V\n[ ] Endianness: little-endian / big-endian\n[ ] Linking type: statically linked / dynamically linked\n[ ] Security features: PIE / ASLR / NX/DEP / Stack Canary / RELRO\n[ ] Packing detected: UPX / Themida / custom (high entropy sections)\n[ ] Compiler identified: GCC / MSVC / Clang / Rust / Go\n[ ] Interesting strings: URLs, IPs, credentials, file paths\n[ ] Import/Export table: suspicious API calls\n[ ] Entry point and sections mapping\n```\n\n**Security feature detection:**\n```bash\n# Linux: checksec (from pwntools)\nchecksec --file=./binary\n\n# Or check manually:\nreadelf -l binary | grep GNU_STACK    # NX bit\nreadelf -d binary | grep RELRO        # RELRO\n```\n\n### 2. Assembly Code Interpretation\n\n**When the user pastes disassembled code or Ghidra decompilation:**\n\nClaude will:\n1. Identify the architecture from instruction syntax\n2. Trace execution flow from the provided entry point\n3. Identify function calls (call/bl/jal instructions)\n4. Reconstruct high-level logic from the assembly\n5. Annotate each block with a comment explaining its purpose\n6. Flag security-relevant patterns\n\n**Common x86-64 Patterns:**\n\n| Pattern | Instructions | Meaning |\n|---------|--------------|---------|\n| Function prologue | `push rbp; mov rbp, rsp; sub rsp, N` | Stack frame setup |\n| Function epilogue | `leave; ret` or `pop rbp; ret` | Stack frame teardown |\n| Local variable | `mov [rbp-N], rax` | Store value on stack |\n| Loop counter | `cmp rax, N; jl/jge loop_top` | Loop with counter |\n| Buffer on stack | `sub rsp, 0x100` | 256-byte local buffer |\n| String copy | `rep movsb` | Memory copy |\n| Memset | `rep stosb` | Memory zero/fill |\n| Switch-case | Indirect jump: `jmp [rax*8 + table]` | Jump table |\n| System call (Linux) | `mov rax, N; syscall` | Direct system call |\n| Printf/format string | `lea rdi, [rip+str]; call printf@plt` | Print statement |\n| Heap allocation | `call malloc` / `call operator new` | Dynamic memory |\n\n**Common ARM64 Patterns:**\n| Pattern | Instructions | Meaning |\n|---------|--------------|---------|\n| Function prologue | `stp x29, x30, [sp, #-N]!` | Save frame pointer & LR |\n| Return | `ret` (uses x30) | Return from function |\n| Load/store pair | `ldp/stp` | Load/store two registers |\n| Branch + link | `bl func` | Call function |\n| Conditional branch | `b.eq / b.ne / b.lt` | Conditional jump |\n| System call | `svc #0` | System call |\n\n**Crypto constant detection:**\n```python\n# Common crypto constants to watch for:\nAES_SBOX = bytes.fromhex(\"637c777bf26b6fc5...\") # AES SubBytes table\nSHA256_K = [0x428a2f98, 0x71374491, ...]         # SHA-256 round constants\nRC4_INIT_PATTERN                                   # Sequential 0x00-0xFF\n```\n\n### 3. Firmware Reverse Engineering\n\n**When the user asks to analyze embedded firmware:**\n\n```bash\n# Step 1: Identify firmware format\nfile firmware.bin\nbinwalk firmware.bin\n\n# Step 2: Extract filesystem\nbinwalk -e firmware.bin\n# Extracts to _firmware.bin.extracted/\n\n# Step 3: Analyze extracted filesystem\nls -la _firmware.bin.extracted/\nfind . -name \"*.cgi\" -o -name \"passwd\" -o -name \"shadow\" -o -name \"*.conf\"\n\n# Step 4: Find sensitive data\ngrep -r \"password\\|admin\\|secret\\|key\" . --include=\"*.conf\" --include=\"*.xml\"\n\n# Step 5: Find binary entry points\nfile _firmware.bin.extracted/bin/*\nstrings -a httpd | grep -E \"(password|auth|key)\"\n```\n\n**Firmware Analysis Checklist:**\n```\n[ ] Identify firmware packaging format (SquashFS, JFFS2, CPIO, raw)\n[ ] Extract filesystem using binwalk -e\n[ ] Identify target OS and RTOS (Linux, VxWorks, ThreadX, FreeRTOS)\n[ ] Find hardcoded credentials in /etc/passwd, config files, binaries\n[ ] Identify web interface binaries (httpd, lighttpd, uhttpd)\n[ ] Check for debug interfaces (JTAG, UART, SSH enabled)\n[ ] Identify update mechanism and signing verification\n[ ] Search for private keys, certificates, API keys\n[ ] Check for command injection in shell scripts and CGI handlers\n[ ] Map memory layout from linker scripts or binary headers\n```\n\n### 4. Protocol Reverse Engineering\n\n**When the user wants to reverse engineer a protocol:**\n\n**Given captured traffic or binary data:**\n\n1. **Frame structure analysis** — Look for:\n   - Magic bytes or sync patterns (fixed byte sequences at start)\n   - Length fields (2 or 4 bytes, often at offset 2-4)\n   - Message type/command identifier (1-2 bytes)\n   - Checksum/CRC (last 1-4 bytes)\n   - Padding patterns (0x00 or 0xFF fills)\n\n2. **Field type identification:**\n   ```\n   Common field patterns:\n   - 4 bytes, big-endian, values 0-65535 → likely length or port\n   - 16 bytes uniform random → UUID or AES key\n   - Null-terminated variable sequence → ASCII string\n   - Fixed 4 bytes: 0xDEADBEEF, 0xCAFEBABE → magic number\n   ```\n\n3. **Command-response mapping** — Analyze pairs to find:\n   - Request: specific type byte → Response: matching acknowledgment\n   - Error responses: common error code patterns\n\n4. **State machine construction:**\n   ```\n   [INIT] → send magic handshake → [AUTH] → send credentials →\n   [CONNECTED] → send commands → [DATA] → receive data → [IDLE]\n   ```\n\n5. **Generate parser code:**\n   ```python\n   import struct\n   \n   MAGIC = b\"\\xDE\\xAD\\xBE\\xEF\"\n   \n   def parse_packet(data: bytes) -> dict:\n       if not data.startswith(MAGIC):\n           raise ValueError(\"Invalid magic bytes\")\n       \n       msg_type, length = struct.unpack(\">HH\", data[4:8])\n       payload = data[8:8 + length]\n       checksum = struct.unpack(\">H\", data[8 + length:8 + length + 2])[0]\n       \n       return {\n           \"type\": msg_type,\n           \"length\": length,\n           \"payload\": payload,\n           \"checksum\": checksum\n       }\n   ```\n\n### 5. Anti-Reversing Technique Identification & Bypass\n\n**When the user encounters anti-analysis measures:**\n\n| Technique | Indicators | Bypass |\n|-----------|-----------|--------|\n| UPX packing | `UPX!` string, high entropy | `upx -d binary` |\n| Anti-debug: IsDebuggerPresent | API call in imports | Patch: NOP or force return 0 |\n| Anti-debug: ptrace check | `ptrace(PTRACE_TRACEME)` | GDB: `catch syscall ptrace` + return 1 |\n| Timing checks | RDTSC, GetTickCount loops | Patch jumps or NOP timing checks |\n| VM detection | Check for VMware registry/files | Run on bare metal or patch |\n| String encryption | No readable strings, XOR loops | Find decryption routine, set breakpoint after |\n| Control flow flattening | Switch dispatch with state machine | Trace execution to map real CFG |\n| Code virtualization | Custom VM interpreter | Analyze VM bytecode semantics |\n| Self-modifying code | WriteProcessMemory, VirtualProtect | Set breakpoint at write target |\n\n**Ghidra scripting for automation:**\n```java\n// Ghidra script: find all XOR loops (common string decryption)\nFunctionManager fm = currentProgram.getFunctionManager();\nfor (Function f : fm.getFunctions(true)) {\n    // Analyze function for XOR instructions\n    // Flag functions with XOR + loop patterns\n}\n```\n\n### 6. CTF Binary Challenges\n\n**When the user is working on a CTF challenge (pwn/rev category):**\n\n**Quick CTF triage:**\n```bash\n# Check protections\nchecksec --file=./challenge\n\n# Find win functions, hidden strings\nstrings ./challenge | grep -i \"flag\\|win\\|cat\\|/bin\"\nobjdump -d ./challenge | grep -A2 \"win\\|backdoor\\|system\"\n\n# Run with strace to see syscalls\nstrace ./challenge < /dev/null 2>&1 | head -50\n\n# Dynamic analysis with pwndbg\ngdb ./challenge\n# In GDB:\n# info functions       → list all functions\n# disas main           → disassemble main\n# b *0x401234          → breakpoint at address\n# r < input.txt        → run with input\n```\n\n**Common CTF patterns:**\n- `gets()` / `scanf(\"%s\")` without bounds → stack buffer overflow\n- `printf(user_input)` without format string → format string vulnerability\n- `strcmp(input, flag)` → timing attack or direct comparison\n- Custom cipher with key → find key, XOR to decrypt\n- VM-based challenge → trace bytecode execution to find flag check\n\n---\n\n## Output Standards\n\nWhen analyzing binaries, Claude produces:\n- **File summary**: type, arch, security features\n- **Function list**: key functions and their purpose\n- **Annotated disassembly**: line-by-line explanation\n- **Vulnerability assessment**: security issues found in the code\n- **Pseudocode reconstruction**: high-level equivalent of the assembly\n\n---\n\n## Script Reference\n\n### `binary_analyzer.py`\n```bash\n# Full static analysis\npython scripts/binary_analyzer.py --file suspicious.elf --output analysis.json\n\n# Extract strings and imports only\npython scripts/binary_analyzer.py --file malware.exe --strings --imports\n\n# Entropy analysis (detect packing/encryption)\npython scripts/binary_analyzer.py --file firmware.bin --entropy\n```\n\n---\n\n## Skill Integration\n\n| Condition | Adjacent Skill |\n|-----------|---------------|\n| Sample needs dynamic behavioral analysis | → Skill 05 (Malware Analysis) |\n| Vulnerability found → develop exploit | → Skill 03 (Exploit Development) |\n| Extract IOCs from analysis | → Skill 06 (Threat Hunting) |\n| Create detection from findings | → Skill 15 (Blue Team Defense) |\n\n---\n\n## References\n\n- [Ghidra Official Documentation](https://ghidra-sre.org/)\n- [radare2 Book](https://book.rada.re/)\n- [Intel x86-64 Software Developer Manual](https://www.intel.com/content/www/us/en/developer/articles/technical/intel-sdm.html)\n- [ARM Architecture Reference Manual](https://developer.arm.com/documentation/)\n- [ELF Specification (Linux Foundation)](https://refspecs.linuxfoundation.org/elf/elf.pdf)\n- [PE ","tagline":"Binary analysis, assembly interpretation, disassembly, decompilation, firmware RE, and protocol reverse engineering","category":"automation","tags":["cybersecurity","reverse-engineering","binary-analysis","disassembly","firmware","assembly","ctf","agent-skill"],"author":"Masriyan","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"Masriyan/Claude-Code-CyberSecurity-Skill","creatorName":"Masriyan","creatorUrl":"https://github.com/Masriyan","sourceUrl":"https://github.com/Masriyan/Claude-Code-CyberSecurity-Skill/tree/main/skills/04-reverse-engineering","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/masriyan-reverse-engineering-binary-analysis#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
