VERDICT —OUT OF SCOPE
Root cause is private-key / signer compromise — the on-chain contract behaved exactly as written. No pre-deployment source audit or bytecode review reaches the key-custody perimeter; this is operational-security territory (HSM/MPC hygiene, key rotation, hot-wallet isolation). Bytecode would show nothing wrong.

Forensic narrative
Cybersecurity startup Unciphered has carried out an attack on encrypted hardware wallets made by OneKey. In a video on YouTube, Unciphered demonstrates a so-called "man-in-the-middle" wallet attack method that exploits a vulnerability to extract a mnemonic seed phrase, or private key, from a OneKey Mini hardware wallet. OneKey acknowledged the vulnerability in a statement and said that no one was affected as it had updated the security patch. OneKey said it has paid a bounty to Unciphered. Attack method (per SlowMist): "Man-in-the-middle" attack. Reported loss: -.
