Taiwan-based cryptocurrency exchange BitoPro experienced a security incident where over $11.5 million in crypto was drained from its hot wallets on May 8.
The suspicious transactions involved outflows to decentralized exchanges (DEXs) across Ethereum, Tron, Solana, and Polygon, with assets later marked as sold.
Blockchain data revealed funds were sent to Tornado Cash or bridged to Bitcoin via THORChain to obscure their origin, tactics commonly used by hackers.
BitoPro announced a maintenance period on May 9 but has not disclosed the incident publicly, while users reported issues with withdrawing funds.
