ALERT: ZeuS GameOver Massive Spamming Campaign Now Targeting Banks & Enterprises

Share Button

Today, our research team has confirmed a massive spam campaign leveraging ZeuS GameOver, is now targeting major banks, social networks, and other enterprises.

How is the spamming taking place?

Hundreds of unsolicited emails, impersonating “Broad Oak Toiletries Ltd”, are targeting these organizations. To inspire trust, the emails have the word Invoice and a few random numbers on the subject line and pretends to have been scanned by Symantec Email Security cloud service. In the body of the email, the recipients are being asked to communicate a payment date to an account administrator for the invoice attached.

The email includes a ZIP archive named ‘Invoice [random number] March’ and contains an executable file posing as a Word document. Upon opening, the file will attempt to download a binary form of 55 different URLs. Following this, approximately 35 websites will be serving up the payload of ZeuS GameOver, with the Narcus rootkit and some ransomware.

While we can't definitively say what the source of the breach was, the percentage of Extremely High Value cards is significantly higher than we see on average. These are cards like the Amex Centurion card - an invite-only card that comes with a $7500 setup fee, and $2500 annual fee. While it is hard to determine from a single black market, this would indicate these could come from a high end source, such as Neiman Marcus.
