Galanis wrote on Twitter that he "Just got my Apple ID hacked". Although he didn't offer more details on how he had determined iCloud was to blame, it's likely he's referring to an attack vector where MetaMask automatically backs up users' seed phrases to iCloud unless it's disabled, meaning that a hacker who successfully accesses a person's iCloud account can also compromise any of their MetaMask wallets. The same type of attack saw a user lose $650,000 in April, and brought wider attention to the app's behavior.
