Reverse Engineering & Binary Analysis

Purpose

Enable Claude to assist with reverse engineering tasks including binary analysis, assembly interpretation, decompilation, firmware reverse engineering, and protocol analysis. Claude directly reads and interprets disassembled code, identifies patterns, reconstructs logic, and helps navigate complex binaries using RE tool output.

Activation Triggers

This skill activates when the user asks about:

  • Analyzing an ELF, PE (exe/dll), Mach-O, or raw binary
  • Interpreting x86, x64, ARM, MIPS, or RISC-V assembly code
  • Reverse engineering firmware from embedded/IoT devices
  • Reverse engineering a network protocol
  • Using Ghidra, IDA Pro, radare2, or Binary Ninja output
  • Identifying what a binary or function does
  • Finding vulnerabilities in disassembly
  • CTF binary challenges (pwn, reversing categories)
  • Anti-debugging or anti-analysis technique identification
  • Unpacking or deobfuscating binaries

Prerequisites

pip install capstone pyelftools pefile lief

Recommended RE tools:

  • Ghidra — NSA open-source RE framework (free)
  • radare2 / Cutter — Open-source RE framework
  • Binary Ninja — Commercial RE platform with scripting
  • IDA Pro / Free — Industry standard disassembler
  • GDB + GEF/PEDA/pwndbg — Dynamic debugging
  • Binwalk — Firmware extraction and analysis
  • strings, file, objdump, readelf — Standard Linux utilities

Core Capabilities

1. Initial Binary Triage

When the user provides a binary or asks what a file is:

Run these commands and share output with Claude for analysis:

# File type identification
file suspicious_binary

# Strings extraction (often reveals C2, keys, paths)
strings -a suspicious_binary | grep -E "(http|/etc|password|key|secret|flag)"

# ELF analysis
readelf -a suspicious_binary
objdump -d suspicious_binary | head -100

# PE analysis
python scripts/binary_analyzer.py --file malware.exe --strings --imports

# Entropy analysis (high entropy = packed/encrypted)
python scripts/binary_analyzer.py --file binary --entropy

Binary Triage Checklist:

[ ] File type and format (magic bytes): ELF / PE / Mach-O / raw
[ ] Target architecture: x86 / x64 / ARM32 / ARM64 / MIPS / RISC-V
[ ] Endianness: little-endian / big-endian
[ ] Linking type: statically linked / dynamically linked
[ ] Security features: PIE / ASLR / NX/DEP / Stack Canary / RELRO
[ ] Packing detected: UPX / Themida / custom (high entropy sections)
[ ] Compiler identified: GCC / MSVC / Clang / Rust / Go
[ ] Interesting strings: URLs, IPs, credentials, file paths
[ ] Import/Export table: suspicious API calls
[ ] Entry point and sections mapping

Security feature detection:

# Linux: checksec (from pwntools)
checksec --file=./binary

# Or check manually:
readelf -l binary | grep GNU_STACK    # NX bit
readelf -d binary | grep RELRO        # RELRO
2. Assembly Code Interpretation

When the user pastes disassembled code or Ghidra decompilation:

Claude will:

  1. Identify the architecture from instruction syntax
  2. Trace execution flow from the provided entry point
  3. Identify function calls (call/bl/jal instructions)
  4. Reconstruct high-level logic from the assembly
  5. Annotate each block with a comment explaining its purpose
  6. Flag security-relevant patterns

Common x86-64 Patterns:

PatternInstructionsMeaning
Function prologuepush rbp; mov rbp, rsp; sub rsp, NStack frame setup
Function epilogueleave; ret or pop rbp; retStack frame teardown
Local variablemov [rbp-N], raxStore value on stack
Loop countercmp rax, N; jl/jge loop_topLoop with counter
Buffer on stacksub rsp, 0x100256-byte local buffer
String copyrep movsbMemory copy
Memsetrep stosbMemory zero/fill
Switch-caseIndirect jump: jmp [rax*8 + table]Jump table
System call (Linux)mov rax, N; syscallDirect system call
Printf/format stringlea rdi, [rip+str]; call printf@pltPrint statement
Heap allocationcall malloc / call operator newDynamic memory

Common ARM64 Patterns:

PatternInstructionsMeaning
Function prologuestp x29, x30, [sp, #-N]!Save frame pointer & LR
Returnret (uses x30)Return from function
Load/store pairldp/stpLoad/store two registers
Branch + linkbl funcCall function
Conditional branchb.eq / b.ne / b.ltConditional jump
System callsvc #0System call

Crypto constant detection:

# Common crypto constants to watch for:
AES_SBOX = bytes.fromhex("637c777bf26b6fc5...") # AES SubBytes table
SHA256_K = [0x428a2f98, 0x71374491, ...]         # SHA-256 round constants
RC4_INIT_PATTERN                                   # Sequential 0x00-0xFF
3. Firmware Reverse Engineering

When the user asks to analyze embedded firmware:

# Step 1: Identify firmware format
file firmware.bin
binwalk firmware.bin

# Step 2: Extract filesystem
binwalk -e firmware.bin
# Extracts to _firmware.bin.extracted/

# Step 3: Analyze extracted filesystem
ls -la _firmware.bin.extracted/
find . -name "*.cgi" -o -name "passwd" -o -name "shadow" -o -name "*.conf"

# Step 4: Find sensitive data
grep -r "password\|admin\|secret\|key" . --include="*.conf" --include="*.xml"

# Step 5: Find binary entry points
file _firmware.bin.extracted/bin/*
strings -a httpd | grep -E "(password|auth|key)"

Firmware Analysis Checklist:

[ ] Identify firmware packaging format (SquashFS, JFFS2, CPIO, raw)
[ ] Extract filesystem using binwalk -e
[ ] Identify target OS and RTOS (Linux, VxWorks, ThreadX, FreeRTOS)
[ ] Find hardcoded credentials in /etc/passwd, config files, binaries
[ ] Identify web interface binaries (httpd, lighttpd, uhttpd)
[ ] Check for debug interfaces (JTAG, UART, SSH enabled)
[ ] Identify update mechanism and signing verification
[ ] Search for private keys, certificates, API keys
[ ] Check for command injection in shell scripts and CGI handlers
[ ] Map memory layout from linker scripts or binary headers
4. Protocol Reverse Engineering

When the user wants to reverse engineer a protocol:

Given captured traffic or binary data:

  1. Frame structure analysis — Look for:

    • Magic bytes or sync patterns (fixed byte sequences at start)
    • Length fields (2 or 4 bytes, often at offset 2-4)
    • Message type/command identifier (1-2 bytes)
    • Checksum/CRC (last 1-4 bytes)
    • Padding patterns (0x00 or 0xFF fills)

  2. Field type identification:

    Common field patterns:
- 4 bytes, big-endian, values 0-65535 → likely length or port
- 16 bytes uniform random → UUID or AES key
- Null-terminated variable sequence → ASCII string
- Fixed 4 bytes: 0xDEADBEEF, 0xCAFEBABE → magic number

  3. Command-response mapping — Analyze pairs to find:

    • Request: specific type byte → Response: matching acknowledgment
    • Error responses: common error code patterns

  4. State machine construction:

    [INIT] → send magic handshake → [AUTH] → send credentials →
[CONNECTED] → send commands → [DATA] → receive data → [IDLE]

  5. Generate parser code:

    import struct

MAGIC = b"\xDE\xAD\xBE\xEF"

def parse_packet(data: bytes) -> dict:
    if not data.startswith(MAGIC):
        raise ValueError("Invalid magic bytes")
    
    msg_type, length = struct.unpack(">HH", data[4:8])
    payload = data[8:8 + length]
    checksum = struct.unpack(">H", data[8 + length:8 + length + 2])[0]
    
    return {
        "type": msg_type,
        "length": length,
        "payload": payload,
        "checksum": checksum
    }
5. Anti-Reversing Technique Identification & Bypass

When the user encounters anti-analysis measures:

TechniqueIndicatorsBypass
UPX packingUPX! string, high entropyupx -d binary
Anti-debug: IsDebuggerPresentAPI call in importsPatch: NOP or force return 0
Anti-debug: ptrace checkptrace(PTRACE_TRACEME)GDB: catch syscall ptrace + return 1
Timing checksRDTSC, GetTickCount loopsPatch jumps or NOP timing checks
VM detectionCheck for VMware registry/filesRun on bare metal or patch
String encryptionNo readable strings, XOR loopsFind decryption routine, set breakpoint after
Control flow flatteningSwitch dispatch with state machineTrace execution to map real CFG
Code virtualizationCustom VM interpreterAnalyze VM bytecode semantics
Self-modifying codeWriteProcessMemory, VirtualProtectSet breakpoint at write target

Ghidra scripting for automation:

// Ghidra script: find all XOR loops (common string decryption)
FunctionManager fm = currentProgram.getFunctionManager();
for (Function f : fm.getFunctions(true)) {
    // Analyze function for XOR instructions
    // Flag functions with XOR + loop patterns
}
6. CTF Binary Challenges

When the user is working on a CTF challenge (pwn/rev category):

Quick CTF triage:

# Check protections
checksec --file=./challenge

# Find win functions, hidden strings
strings ./challenge | grep -i "flag\|win\|cat\|/bin"
objdump -d ./challenge | grep -A2 "win\|backdoor\|system"

# Run with strace to see syscalls
strace ./challenge < /dev/null 2>&1 | head -50

# Dynamic analysis with pwndbg
gdb ./challenge
# In GDB:
# info functions       → list all functions
# disas main           → disassemble main
# b *0x401234          → breakpoint at address
# r < input.txt        → run with input

Common CTF patterns:

  • gets() / scanf("%s") without bounds → stack buffer overflow
  • printf(user_input) without format string → format string vulnerability
  • strcmp(input, flag) → timing attack or direct comparison
  • Custom cipher with key → find key, XOR to decrypt
  • VM-based challenge → trace bytecode execution to find flag check

Output Standards

When analyzing binaries, Claude produces:

  • File summary: type, arch, security features
  • Function list: key functions and their purpose
  • Annotated disassembly: line-by-line explanation
  • Vulnerability assessment: security issues found in the code
  • Pseudocode reconstruction: high-level equivalent of the assembly

| Printf/format string | `lea rdi, [rip+str]; call printf@plt` | Print statement |
| Heap allocation | `call malloc` / `call operator new` | Dynamic memory |

**Common ARM64 Patterns:**

| Branch + link | `bl func` | Call function |
| Conditional branch | `b.eq / b.ne / b.lt` | Conditional jump |
| System call | `svc #0` | System call |

**Crypto constant detection:**
```python
# Common crypto constants to watch for:
AES_SBOX = bytes.fromhex("637c777bf26b6fc5...") # AES SubBytes table
SHA256_K = [0x428a2f98, 0x71374491, ...]         # SHA-256 round constants
RC4_INIT_PATTERN                                   # Sequential 0x00-0xFF
```

### 3. Firmware Reverse Engineering

**When the user asks to analyze embedded firmware:**

```bash
# Step 1: Identify firmware format
file firmware.bin
binwalk firmware.bin

# Step 2: Extract filesystem
binwalk -e firmware.bin
# Extracts to _firmware.bin.extracted/

# Step 3: Analyze extracted filesystem
ls -la _firmware.bin.extracted/

### 5. Anti-Reversing Technique Identification & Bypass

**When the user encounters anti-analysis measures:**

| Technique | Indicators | Bypass |
|-----------|-----------|--------|
| UPX packing | `UPX!` string, high entropy | `upx -d binary` |
| Anti-debug: IsDebuggerPresent | API call in imports | Patch: NOP or force return 0 |
| Anti-debug: ptrace check | `ptrace(PTRACE_TRACEME)` | GDB: `catch syscall ptrace` + return 1 |
| Timing checks | RDTSC, GetTickCount loops | Patch jumps or NOP timing checks |
| VM detection | Check for VMware registry/files | Run on bare metal or patch |
| String encryption | No readable strings, XOR loops | Find decryption routine, set breakpoint after |
| Control flow flattening | Switch dispatch with state machine | Trace execution to map real CFG |
| Code virtualization | Custom VM interpreter | Analyze VM bytecode semantics |
| Self-modifying code | WriteProcessMemory, VirtualProtect | Set breakpoint at write target |

**Ghidra scripting for automation:**
```java
// Ghidra script: find all XOR loops (common string decryption)
FunctionManager fm = currentProgram.getFunctionManager();
for (Function f : fm.getFunctions(true)) {
    // Analyze function for XOR instructions
    // Flag functions with XOR + loop patterns
}
```
