DHL tracking number emails contain malware (Troj/Bckdr-QSL)

DHL delivery malicious email

Of course, the emails are not really from DHL.

If you open the file inside the attachment (called you will be infected by the Troj/Bckdr-QSL backdoor Trojan horse, which will attempt to take control of your PC.

My sister got hit with this via email in a 0-day attack - she was infected as of 8 AM on Monday, 23 March. Symantec did not find anything, at first, until she had already run the executable inside the ZIP file, and it started downloading known viruses. This is a pretty generic Trojan that downloads other trojans and backdoors and viruses to the system and begins a systematic onslaught on the machine, starting with adding proxy settings to IE redirecting it to a local 'server' running on port 7171, and going from there.

The bad news is that when it hoses IE, it also hoses MBAM's ability to update - but fortunately, Sophos has already added it to their definition collection (called IDEs) and you can follow the instructions at Sophos - Removing Trojans including the downloading of the IDEs from Sophos - Download latest virus identity (IDE) files to get rid of most of the infections. Once this is done you can then reset IE to default settings (or, as I walked her through, manually check all your settings (a painstaking 1 hour 25 minute process - We checked *everything* and I had he change some settings that would make her IE a little bit safer) and then you can update MBAM and run a full scan to find the rest of the little buggers and clean yer system.

Her explorer.exe may still be hosed, we'll see - all of this is performed in Safe Mode.

Just to give you and idea - she first called me at 9:56 PM yesterday - and it is now 3:10 AM....

EDIT: Added the following:

Also, Sophos found 1 item corrupt (word doc), 1 was PW protected (a legitimate PW protected Excel spreadshhet - she's a mortgage officer), and a third that it was unable to remove (Major malware) - and it removed 3 viruses.

Then, MBAM comes back and finds *all* of these:
