Firmware Extraction:\n```bash\nbinwalk -e firmware.bin\n```\nOutput:\n- Squashfs filesystem extracted\n- Multiple directories found\n\n2. Credential Discovery:\n```bash\ngrep -r \"password\" etc/\n```\nOutput:\n- admin:admin123\n- root:root\n- Default credentials found\n\n3. Web Interface:\n```bash\ncat www/cgi-bin/admin.cgi\n```\nOutput:\n- Command injection possible\n- No input validation\n- Direct system access\n\n4. Network Services:\n```bash\nnetstat -tlnp\n```\nOutput:\n- Port 22: SSH\n- Port 80: HTTP\n- Port 443: HTTPS\n- Port 31337: Debug (no auth)\n\n5. Vulnerabilities:\n- Default credentials\n- Command injection\n- Debug interface exposed\n- Hardcoded keys\n\nIndicators:\n- Default passwords\n- Debug interfaces\n- Command injection\n- Hardcoded credentials\n\nRemediation:\n1. Change default passwords\n2. Disable debug interfaces\n3. Implement input validation\n4. Remove hardcoded credentials\n5. Regular firmware updates",
