BOATBEAM is a Golang-based backdoor used by the financially motivated BREEZE COMET threat actor, also tracked as UNC5669. It provides redundant persistent access in intrusions targeting Brazilian financial-services, payment, retail, and e-commerce organizations. BOATBEAM masquerades its command-and-control traffic as an IIS HTTPS service and only activates when presented with a designated session cookie, helping conceal its network communications. BREEZE COMET has used BOATBEAM alongside LIGHTPAINT, MILDFROST, and KICKPLATE while pursuing access to banking software, payment APIs, and systems supporting fraudulent financial transfers.
