Executing the malware

The bad guys never sleep. A recent trend has been fake invoice emails that contain malware, the attachments often disguised as PDF files while in fact they are executables. Other schemes involve zipping the bad files, a technique that often by-passes spam filters.

We have now put a stop to this nonsense. Incoming email with zip attachments will now be denied if the zips contain executable files. No more fake invoices in your inbox. Executed!
