Once again, internet users are being warned to be suspicious of unsolicited emails, as a malware attack poses as a communication from the Federal Deposit Insurance Corporation (FDIC) to businesses.
SophosLabs has intercepted a large number of malicious emails, pretending to come from FDIC that claim to have important information about the recipient’s bank.
Attached to the emails is a ZIP file which contains a malicious payload, designed to infect Windows computers.
Here is a typical message:
Dear Business Customer,
We have important information about your bank.
Please refer to attached file to view information.
This includes information on the acquiring bank (if applicable), how your accounts and loans are affected, and how vendors can file claims against the receivership
The emails' subject line is "FDIC: About your business account", followed by a random code number. The attached filename, containing the malware, is FDIC_Information_About-your-business-account-JAN2012-XXXXX.zip (where 'XXXXX' is a random number).
Sophos anti-virus products detect the attachment proactively as Mal/BredoZp-B and Mal/Zbot-EZ.
