Bad news for SMBs: Target’s “Backoff” malware attack hits 1,000 more businesses
More than 1,000 U.S. businesses have had their systems infected by Backoff, a point-of-sale (PoS) malware that was linked to the remote-access attacks against Target, Michaels, and P.F. Chang’s last year and more recently, UPS and Dairy Queen. In the Target breach alone, 40 million credit and debit cards were stolen, along with 70 million records which included the name, address, email address, and phone number of Target shoppers.
The way these breaches occur is laid out in BACKOFF: New Point of Sale Malware, a new U.S. Department of Homeland Security (DHS) report. Investigations reveal that cybercrooks use readily available tools to identify businesses that use remote desktop applications which allow a user to connect to a computer from a remote location. The Target breach began with stolen login credentials from the air-conditioning repairman.
Once the business is identified, the hackers use brute force to break into the login feature of the remote desktop solution. After gaining access to administrator or privileged access accounts, the cybercrooks are then able to deploy the PoS malware and steal consumer payment data. If that’s not enough, most versions of Backoff have keylogging functionality and can also upload discovered data, update the malware, download/execute further malware, and uninstall the malware.
