According to news shared by Changpeng Zhao via BitcoinNewsCom, an estimated 64,000 Bitcoin mining machines, representing a total hashrate of approximately 13 EH/s, were unauthorizedly redirected to the OCEAN mining pool, with their payout addresses set to attacker-controlled addresses. The report, citing a subsequent update from CoreX Hosting, stated that the hijacked hashrate has dropped back to around 100 PH/s, adding that the attacker did not mine any blocks during the incident. The full scope of the event and whether related management software was compromised have not yet been independently confirmed.
