Apple: Some Mac users are getting hit with ransomware -- here's what to do

Mac Users Targeted in iCloud Ransomware Attack

Several Mac users have reported being locked out of their devices after hackers exploited stolen iCloud credentials to remotely activate Find My Mac and demand a $50 Bitcoin ransom. The attacks, first highlighted by MacRumors, involve threat actors using compromised usernames and passwords to lock victims’ computers, displaying a ransom message in chatspeak.

Apple has confirmed the incidents, noting that affected users must visit an Apple Store with proof of identity to regain access. Alternatively, victims face either paying the ransom with no guarantee of recovery or performing a hard reset, which erases all data.

The breach highlights a broader security issue: hackers likely obtained credentials through phishing scams, fake virus alerts, or weak passwords. While Apple has not disclosed the scale of the attacks, the incident underscores vulnerabilities in account security, particularly for users without two-factor authentication (2FA) enabled. Disabling Find My Mac may reduce risk for unaffected users.
