Apple computers have been successfully targeted by malicious software called “ransomware” for the first time, according to security researchers.
Palo Alto Networks said it spotted the ransomware on OS X on March 4, and reported the issue to Apple the same day.
Apple, which did not immediately respond to CNNMoney’s requests for comment, took steps to protect users after being alerted to the problem, Palo Alto said.
Ransomware is software that hijacks a computer, and locks a user’s files until a ransom is paid. The program in question, dubbed keRanger, requires victims to pay one Bitcoin, which is a little more than $400, to retrieve their files.
