Security researchers from Sophos, have intercepted a currently circulating Mac OS X malware variant of the OSX/Imuler trojan horse.

OSX/Imuler-B uses images of supermodel Irina Shayk in an attempt to trick end users into execution the malicious application. The cybercriminals behind the campaign are relying on the fact that by default, Mac OS X doesn't display full file extensions, and therefore are attempting to trick end and corporate users into thinking that they're about the view a JPG image file.

Upon execution the malware will delete the original infection file and only leave an image file of Irina Shayk. It will also open a backdoor on the infected host, transferring private information from the infected host to a remote Web server.

End and corporate users are advised to turn on "Show all filename extensions" option in Finder in order to differentiate between different file types and avoid interacting with malicious applications.
