The new malware variant, OSX/Imuler-B, uses images of supermodel Irina Shayk in an attempt to trick end users into execution the malicious application. The malware relies on the fact that by default, Mac OS X doesn’t display full file extensions, and therefore is attempting to trick users into thinking that they’re about the view a JPG image file.

Once the file is executed 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.

So what can you do to prevent infection?

  • Turn on “Show all filename extensions” option in Finder in order to differentiate between different file types.  This way, you will know if you are opening an image file or something malicious.
