The PCI Council warns organizations about the risks associated with the Backoff point-of-sale malware. The alert follows an advisory from the Department of Homeland Security, which estimated that more than 1,000 US businesses have had their systems infected by Backoff, a new point-of-sale malware that has been linked to numerous remote-access attacks.
To mitigate the malware threat, the PCI Council recommends that organizations:
• Contact anti-virus providers and ensure the organization has a version of the software that detects Backoff and other similar malware;• Run the anti-virus solution immediately;• Review system logs for any unusual or unexplained activity, especially large data files being sent to unknown locations;• Update all default and staff passwords on systems and applications.
The PCI Council also recommends the use of point-to-point encryption, among other steps, to guard against malware threats.
