10 Questions to Ask Suppliers as Part of Third-Party Security Reviews

Summary: Dragos reports that at least six of its designated threat groups - ALLANITE, CHRYSENE, DYMALLOY, HEXANE, RASPITE, and XENOTIME - have used supply chain attacks to gain initial access to target environments, citing SolarWinds as a prime example from the last 12-18 months. The firm notes that beyond software updates and patching, OEMs, vendors, and third-party contractors can provide ingress into ICS/OT environments through compromised or poorly secured direct network connections and remote access software, and that data leaked from a supplier - such as troubleshooting tickets - can be used in later attacks, a technique it attributes to groups like Conti.

Bottom line: Six tracked threat groups treat your supplier as the front door to your OT network, and the access they buy there - remote connections, vendor software, support tickets - is often the same access you granted for legitimate operations.
