⚠️ AUTHORIZED USE ONLY
This skill is for educational purposes or authorized security assessments only.
You must have explicit, written permission from the system owner before using this tool.
Misuse of this tool is illegal and strictly prohibited.
Mandatory confirmation gate
Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:
Ask the user to state the exact target URL, IP, account, or resource.
Ask the user to confirm written authorization and the permitted scope.
Show the exact command(s) and explain their expected effect.
Wait for explicit confirmation in the current conversation.
Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.
UART access - Serial console connection
JTAG/SWD - Debug interface for memory access
SPI flash dump - Direct chip reading
NAND/NOR dump - Flash memory extraction
Chip-off - Physical chip removal and reading
Logic analyzer - Protocol capture and analysis
## Use this skill when
- Working on download from vendor tasks or workflows
- Needing guidance, best practices, or checklists for download from vendor
## Do not use this skill when
- The task is unrelated to download from vendor
- You need a different domain or tool outside this scope
## Instructions
- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open `resources/implementation-playbook.md`.
## Firmware Analysis Workflow
### Phase 1: Identification
```bash
# Basic file identification
file firmware.bin
binwalk firmware.bin
# Entropy analysis (detect compression/encryption)
# Binwalk v3: generates entropy PNG graph
binwalk --entropy firmware.bin
binwalk -E firmware.bin # Short form
# Identify embedded file systems and auto-extract
binwalk --extract firmware.bin
binwalk -e firmware.bin # Short form
# String analysis
strings -a firmware.bin | grep -i "password\|key\|secret"
# Identify architecture
file bin/httpd
readelf -h bin/httpd
# Load in Ghidra with correct architecture# For ARM: specify ARM:LE:32:v7 or similar# For MIPS: specify MIPS:BE:32:default# Set up cross-compilation for testing# ARM
arm-linux-gnueabi-gcc exploit.c -o exploit
# MIPS
mipsel-linux-gnu-gcc exploit.c -o exploit
Common Vulnerability Classes
Authentication Issues
Hardcoded credentials - Default passwords in firmware
Backdoor accounts - Hidden admin accounts
Weak password hashing - MD5, no salt
Authentication bypass - Logic flaws in login
Session management - Predictable tokens
Command Injection
// Vulnerable patternchar cmd[256];
sprintf(cmd, "ping %s", user_input);
system(cmd);
// Test payloads
