FDIC Spam Delivers Malware

Continue to be suspicious and diligent whenever you receive unsolicited emails.  No matter who the sender purports to be, never open those “important attachments”.  A recent malware attack poses as a communication from the Federal Deposit Insurance Corporation (FDIC) to businesses.

SophosLabs has reported interception of a large number of malicious emails, pretending to come from FDIC, claiming to have important information about the recipient’s bank.  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).

Attached to the emails is a ZIP file which contains a malicious payload, designed to infect Windows computers.

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

Sophos anti-virus products detect the attachment proactively as Mal/BredoZp-B and Mal/Zbot-EZ.

One more note worth keeping in mind.  UPS, FedEx and other delivery services are commonly exploited in this kind of scam.  If you aren’t expecting a delivery, don’t open the attachment.  If the email contains a tracking number, go to the delivery service’s website or call them to confirm before opening a surprise attachment from aunt Martha.  Otherwise the surprise might be nastier than her old fuitcake…
