A stranger emails you out of the blue, offering you a digital photo of themselves. The messages have one attachment, called DSC0173519.zip. The ZIP file is encrypted (presumably in an attempt to defeat anti-virus products running at the email gateway sorry Mr Cybercriminal, that didnt stop Sophos) within the ZIP is an executable file, which Sophos proactively detects as Mal/Behav-043. If youre not protected by Sophos, and make the mistake of running the program it will drop another file onto your hard drive – Troj/Agent-REX spyware Trojan horse.”]
