Wallet Vulnerability

Estimated loss

$170.0K

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

Trust Wallet released an analysis report saying: "In November 2022, a vulnerability was discovered in the back-end module WebAssembly (WASM) at the core of the open source repository wallet. The vulnerability affected new wallets generated by browser extension versions 0.0.172 and 0.0.182, and only the private keys of a limited number of new wallets created in these versions were affected. Despite our best efforts, two breaches occurred, resulting in a combined loss of approximately $170,000 at the time of the attack. " Attack method (per SlowMist): Wallet Vulnerability. Reported loss: $ 170,000.
