This morning a unique campaign targeting Macs has caught our attention. This attempt contained a .zip file carrying a Mac (OSX) trojan known as Aptordoc (OSX.Dok).

All of these emails contained the OSX Aptordoc trojan, however, some also had a Windows trojan downloader known as W97M.Dropper (Mal/DocLnk-B) attached, also like the example pictured below.  These messages were sent to our Switzerland clients with the .ch domain extension.

Macs not being susceptible to attacks is a common misconception. While we see less attempts targeting Macs, they are definitely susceptible to malicious attacks such as this.  Below is and example of the current malicious email that is making the rounds. Under the example image is a rough unedited Google Translation to English.
