- AXIS is pushing for Linux apps on cameras, increasing security risks.
- Hanwha Vision cameras have accessible firmware blobs for analysis.
- Initial firmware decryption uses passphrase 'HTW' + model number.
- Inner firmware has AES encryption with key XOR-obfuscated in binary.
- Decryption uses hardcoded key and IV across the model line.
- Reconstructed OpenSSL command reveals key and IV for decryption.
- A GitHub token with admin privileges found in 30 firmware files.
- Token exposure stems from build process dumping CI environment variables.
- CI environment also contained DoD IP addresses, suggesting ties to defense.
- Out of ~500 firmwares, only 3 had the same GitHub token; Hanwha revoked it promptly.
