The well-known Taiwanese cryptocurrency exchange BitoPro has recently been suspected of suffering a hacker attack, attracting widespread attention.
Blockchain security researcher ZachXBT disclosed in early June that since May 8, 2025, multiple hot wallets of BitoPro on public chains such as Ethereum, Tron, Solana, and Polygon have experienced abnormal fund outflows, totaling over 11.5 million US dollars.
The investigation showed that these assets were quickly transferred and exchanged in decentralized exchanges (DEX) within a short period. Some of the funds flowed into the anonymous trading platform Tornado Cash, while the rest were transferred across chains to the Bitcoin network through Thorchain, eventually entering the Wasabi wallet for further money laundering. This process is considered to be a highly professionalized attack.
Although the incident has been widely tracked, BitoPro officially has only suspended some services on the grounds of "system maintenance" and has not directly responded to whether it has encountered a security event, raising concerns about the security of platform assets among users.
Industry insiders point out that this "low-key handling" method might be to assess the losses and seek remedial solutions.
Cybersecurity experts call for trading platforms to promptly disclose the truth of the incident, clarify whether user assets have been affected, and strengthen wallet management and risk control systems to restore market trust and prevent similar incidents from recurring.
