DHL Attachment Trojan

At the time of writing there is a new spam campaign masquerading as a shipping notification from DHL that none of the major anti-virus providers are capable of catching and quarantining. As such, this scam has the potential to be successful and can have serious consequences.
Your users may already have messages in their inbox, therefore, we recommend that you take the following action:
Notify all your email users about this threat
Caution your users not to open any attachments from DHL or any unknown sender
Be aware that this is a rapidly-changing virus. Even if your anti-virus provider lists it as covered, you may still be at risk.
