| 1 | ## Cybersecurity Skills (Invoke First) |
| 2 | |
| 3 | Before starting IoT or firmware testing, invoke these skills via the Skill tool: |
| 4 | - `cybersecurity-skills:performing-iot-security-assessment` |
| 5 | - `cybersecurity-skills:performing-firmware-extraction-with-binwalk` |
| 6 | - `cybersecurity-skills:performing-firmware-malware-analysis` |
| 7 | - `cybersecurity-skills:performing-plc-firmware-security-analysis` |
| 8 | - `cybersecurity-skills:performing-ot-network-security-assessment` |
| 9 | - `cybersecurity-skills:performing-ot-vulnerability-scanning-safely` |
| 10 | - `cybersecurity-skills:monitoring-scada-modbus-traffic-anomalies` |
| 11 | - `cybersecurity-skills:detecting-modbus-command-injection-attacks` |
| 12 | |
| 13 | ## Scope Enforcement |
| 14 | Verify IoT device model/serial or IP address is in scope.txt. |
| 15 | Physical access attacks (UART/JTAG) require device to be explicitly in scope. |
| 16 | OT/ICS attacks MUST use passive monitoring only — NEVER send commands without explicit authorization. |
| 17 | Some attacks can brick devices or disrupt operations. |
| 18 | |
| 19 | ## Firmware Acquisition |
| 20 | ```bash |
| 21 | mkdir -p evidence/$(date +%Y%m%d)/$TARGET/iot/{firmware,fs,strings,network,hardware} |
| 22 | |
| 23 | # Method 1: Download from vendor website |
| 24 | # Search: site:vendor.com firmware download filetype:bin OR filetype:img |
| 25 | curl -s "https://download.$VENDOR.com/firmware/$MODEL-latest.bin" \ |
| 26 | -o evidence/$(date +%Y%m%d)/$TARGET/iot/firmware/firmware.bin 2>&1 |
| 27 | |
| 28 | # Method 2: Extract from running device via TFTP |
| 29 | # On device (if shell available): tftp -g -r /tmp/firmware.bin $LHOST |
| 30 | |
| 31 | # Method 3: Intercept OTA update via mitmproxy |
| 32 | # mitmproxy on device network path, trigger firmware check in app |
