Taiwanese cryptocurrency exchange BitoPro has been hit with a significant security breach that saw over $11.5 million drained from its hot wallets. The hack is believed to have occurred on May 8th and involved the use of Tornado Cash, a crypto mixing tool, to obscure the stolen funds’ trail before being passed through various platforms like Wasabi Wallet for further obfuscation. This attack came after initial signs of suspicious activity were noticed by blockchain sleuths and users began voicing concerns about frozen funds. `, The exchange remained silent for nearly a month after the incident until it finally acknowledged the breach on June 2nd, attributing it to an internal wallet upgrade. Despite their assurance that withdrawals are unaffected, many users have expressed skepticism due to ongoing issues with blocked withdrawals and vague communication.
