The United States Computer Emergency Readiness Team (US-CERT) has issued an advisory warning of a new POS malware that, “at the time of discovery and analysis…had low to zero percent anti-virus detection rates, which means that fully updated anti-virus engines on fully patched computers could not identify the malware as malicious.”

Here is a synopsis of the advisory:

• The malware has the potential to impact any point-of-sale (POS) system where the business is utilizing (or has previously utilized) a remote access tool such as Microsoft’s Remote Desktop, Apple Remote Desktop, Chrome Remote Desktop, Splashtop 2, Pulseway, and LogMEIn.

• The malware, called “Backoff,” has been found in at least 3 separate POS data breach investigations

• There are multiple variants of the malware and merchants are advised to take the necessary, immediate precautions to prevent exposure or limit the damage of a breach that could already be in progress at their busininess

VikingCloud advises merchants to strengthen remote desktop access configurations, network, and POS Security to mitigate the risk of data compromise.
