Threat 2

Not a parcel delivery failure notice, but a Trojan

Threat Name:

Troj/Agent-QGA

Users at Risk:

Windows users

Also Known As:

Symantec: Downloader.Lofog!gen2

Removal Instructions:

Please follow the instructions for removing Trojans.

About:

Seen in spam, it typically features the following subject line:

Subject: Post Express Service. Your package delivered! NR7138

And has the following attachment:

Post_Express_Label_INN1268~.zip, which contains Post Express Label.exe

In general, the email message reads:

Dear client:

Your package has been returned to the Post Express office. The reason of the return is "Error in the delivery address."
Attached to the letter mailing label contains the details of the package delivery.
You have to print mailing label, and come in the Post Express office to receive the packages.
Thank you for using our services.
Post Express Service.

When a user opens the email attachment, the Trojan executes svchost.exe and its subprocess and injects into it, causing it to download more malware.

Document.doc, one of the dropped files, opens with WordPad to disguise its malicious activity. Troj/Agent-QGA may also attempt to contact interviewbuy.ru to download additional files.

The website had been shut down. And while we've seen relation with Mal/Zbot-AV, this is a downloader possibly generated from standard exploit kit so its payload is likely to vary over time.
