In January of this year, a complex malware strain that works across Linux and Windows systems was discovered by security researchers. This backdoor spying software, designed to covertly steal confidential data from machines, was codenamed "Mokes."
Now it looks like the breadth of the Mokes campaign is expanding.
Software security analyst Stefan Orloff recently revealed that the sophisticated cross-platform malware strain now has a variant for OS X.
This rare multi-system triple threat is particularly dangerous because it secretly takes screenshots, logs keystrokes, can take audio/video clips, access a computer's files, and even control a machine remotely if desired.
Basically, the backdoor malware puts a computer, and in this case, any machine running Linux, Windows, or OS X, virtually any computer currently in operation, under a hacker's control.
Similar to the Linux and Windows strain, the OS X variant, called Mokes.A, reportedly takes screenshots of a Mac's display every 30 seconds. It also logs every keystroke a victim makes on the compromised system. The screenshots and key logs are saved in a temporary location on the computer, to be sent to and collected by the attacker's command and control (C & C) server using secure AES-256 encryption.
This combination of screenshots and recorded keystrokes could have devastating consequences. Sensitive information, including credit card numbers, user credentials, and passwords for banking portals and other web accounts can easily be deciphered and stolen using this data.
