Mac malware that infected Facebook bypassed OS X Gatekeeper protection
Researchers have identified the Mac malware that infected employees of Apple, Facebook, and Twitter, and say it may have been used to compromise machines in other US organizations, including auto manufacturers, government agencies, and a leading candy maker, according to a published report.
Pintsized.A is a new family of Mac malware that uses an exploit to bypass Gatekeeper, an OS X protection that allows end users to tightly control which sources are permitted to install apps, according to an article published Monday by The Security Ledger. Mac antivirus provider Intego says the trojan masquerades on infected machines as Linux printing software known as cupsd, although it runs from a different location than the legitimate title. It's unclear exactly how the malware gets around Gatekeeper.
