BitoPro exchange hot wallets compromised through malware deployment on a cloud operations team member via social engineering. Unauthorized withdrawals executed across multiple blockchains during a system update. Attackers attributed to North Korean Lazarus group based on attack patterns and methodology.

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.
