“Your message could not be delivered”. It’s one of the oldest methods in the social-engineering-for spam-and malware-emails handbook. You are receiving notice that an email you sent has not reached its recipient – so sad.

And of course the attachment must contain the mysterious email. But it doesn’t. It contains a zipped variant of MyDoom malware. (First variants of MyDoom were sited on the 26th January 2004). The attachment has wall-to-wall VirusTotal coverage of nearly 98% (42 out of 43 engines including Commtouch’s Command Antivirus).

Email Text:

Your message was undeliverable due to the following reason(s):

Your message could not be delivered because the destination computer was not reachable within the allowed queue period. The amount of time a message is queued before it is returned depends on local configura- tion parameters.

Your message could not be delivered within 6 days:

Host —– is not responding.

The following recipients could not receive this message:
