Yesterday, a new Storm Worm iteration was discovered by Websense Security Labs. The worm works around the theme of the U.S. credit crunch.

To entice victims, the Trojan uses attractive headlines like "The new currency is coming", "Amero arrives", "Amero currency Union is now the reality", and "The AMERO currency replacing the Dollar".

Reportedly, on clicking the link in the spam message, the victim is directed to a site laden with drive-by exploits inside a script file named "ind.php".

The infection success rate is highly dependant on the social engineering tactic employed and thus the malicious file in this campaign is appropriately named "amero.exe", says Websense.

In the past, Storm Worm has used other themes to spread malware with themes related to the "U.S. Independence Day" and news on the fictitious "World War III."

The Websense Messaging Security and Websense Web Security customers are protected against this attack, confirms Websense on their website.
