Fake Auto Identification Card documents

Just received the following email, with a zip file attached (containing an exe file):




















Submitted the file to VirusTotal and the result isn't very good (3/36 scanners):
















Submitting the file to ThreatExpert, gives the following result

"Threat characteristics of ZBot - a banking trojan that disables firewall, steals sensitive financial data (credit card numbers, online banking login details), makes screen snapshots, downloads additional components, and provides a hacker with the remote access to the compromised system."

Fake Contract Documents

Received the following email, which looks the same as a version received about a week ago:

As you can see, it's got a zip attachment, which submitting to VirusTotal, gives us:
















I'd already added a signature to catch the earlier version (11th August) and it also detected this latest version too: Email.Malware.Sanesecurity.08081101 (added 11th August 2008)

Submitting this to ThreatExpert, gives you this worrying result !

Ie: "
Installs a default debugger that is injected into the execution sequence of a target application. If a threat is installed as a default debugger, it will be run every time a target application is attempted to be launched - either to mimic it and hide its own presence (e.g. an open port or a running process), or simply to be activated as often as possible."

As you can see from the stats, it's still being spammed out:









None of this is a worry, to those admins who are blocking exe's inside zip files though :)

However, we do now have popups for some free rogue anti-virus scanning software:
















Needless to say, don't even try to download this!

0 hour UPS Invoice

There was another spam run of the fake UPS invoice yesterday, this time with a different version of the malware, in the zip attachment:








What was interesting, was that the signatures I'd added to catch the last one, detected the new varient too:









As you can see from the above stats graph, Email_Malware_Sanesecurity_08072227
(in yellow) was being blocked from around 5.30pm to 7pm. ClamAV started detecting the attched file at 7pm (Trojan_Zbot_1737).

What does the exe file do? (contained in the zip)... well, here's what ThreatExpert said
