Plump Spider is a financially motivated eCrime threat actor associated with operations targeting organizations in Latin America, particularly Brazil. The group has been linked to campaigns abusing government-themed web infrastructure and counterfeit Brazilian government-style web structures to deliver malware and conduct social-engineering operations. Its activity is associated with fraud-oriented intrusion activity, including credential and session-data theft, keylogging, browser-based data collection, and web-injection or man-in-the-browser techniques intended to capture payment and administrative-system data. Plump Spider overlaps with activity tracked as BREEZE COMET and has also been referenced alongside the designation SHADOW-AETHER-064. The actor is one of several major financially motivated groups operating in or primarily targeting Latin America.
