FIN7

FIN7 is a financially-motivated threat group that has been active since 2013 primarily targeting the U.S. retail, restaurant, and hospitality sectors, often using point-of-sale malware. A portion of FIN7 was run out of a front company called Combi Security. Since 2020 FIN7 shifted operations to a big game hunting (BGH) approach including use of REvil ransomware and their own Ransomware as a Service (RaaS), Darkside. FIN7 may be linked to the Carbanak Group, but there appears to be several groups using Carbanak malware and are therefore tracked separately.[1][2][3][4][5]
