The U.S. Computer Emergency Readiness Team, a division of the Department of Homeland Security, issued a warning to retailers about a new POS malware hack that has been detected.
Dubbed “Backoff,” the family of malware exploits has been found in three separate investigations, going back as far as October 2013.
Backoff uses a variety of methods to compromise the POS, including keylogging and injecting malicious code into explorer.exe. That second one is particularly nasty because it means the exploit will still be there if the machine is turned off or rebooted.
