FIN8 is Back, Targeting Hotel PoS Systems

The hacking group FIN8 is back after a two-year hiatus. According to cybersecurity firm Morphisec, the group is targeting point-of-sale (PoS) systems at companies in the hospitality sector using a new variant of the PunchBuggy/ShellTea backdoor. This backdoor downloads PowerShell code that collects network and user information. The group reportedly targeted at least one hotel located in the US. The NJCCIC recommends individuals ensure they are using chip-and-PIN cards for payments, as opposed to swiping, and for administrators to keep PoS systems updated and behind a firewall. More information and technical details can be found in the Morphisec blog post.
