News broke on May 15 that Coinbase was the target of a $20 million extortion attempt after cybercriminals recruited overseas support agents to leak user data for social engineering scams.<\/p>\n
While less than 1% of Coinbase\u2019s active monthly users were reportedly affected, the expected remediation and reimbursement expenses range from $180 million to $400 million, as the exchange pledged to repay all phishing attack victims.<\/p>\n
