In the past, ransomware was mostly targeted towards Android and Windows users. Researchers at Palo Alto Networks detected the first instances of ransomware amongst Mac products last Friday, when they discovered OS X Bit Torrented infected by ransomware.

Researchers informed Apple of the infection immediately, and Apple reversed the security certificate the ransomware distributors initially bypassed. Apple’s quick response prevented any other users from falling victim to ransomware over the weekend.
