SecondFi wallet exploit losses could top $20M, says security firm

Losses from the exploit of Cardano (ADA) ecosystem wallet SecondFi, formerly Yoroi, could exceed $20 million, according to Cos, founder of blockchain security firm SlowMist. In a post on X, Cos noted that an address believed to belong to the hacker has stolen approximately 129 million ADA and other cryptocurrencies. This estimate significantly surpasses the $2.4 million in damages that SecondFi officially reported 13 hours ago following the vulnerability attack. The project has not yet released any further updates on the hacker's movements or plans for user compensation.
