BitoPro

Malicious Software

Estimated loss

$11.50M

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

According to on-chain investigator ZachXBT, crypto exchange BitoPro was reportedly hacked on May 8, 2025, resulting in losses of approximately $11.5 million. The attacker drained assets from BitoPro’s hot wallets on Tron, Ethereum, Solana, and Polygon, then sold them via DEXs. The stolen funds were subsequently laundered through Tornado Cash or bridged via Thorchain to the Bitcoin network, eventually ending up in a Wasabi Wallet. BitoPro stated that the tactics used in this incident closely resemble those seen in several major international cases, attributing the attack to the North Korean hacking group Lazarus. Attack method (per SlowMist): Malicious Software. Reported loss: $ 11,500,000.
