Still Circling: Blind Eagle’s Toolkit Keeps Evolving

In June 2025, LevelBlue SpiderLabs published Tracing Blind Eagle to Proton66, in which we assessed with high confidence that Blind Eagle (also tracked as APT-C-36, APT-Q-98, TAG-144, AguilaCiega), a threat actor focused on Latin America, had moved part of its VBScript delivery infrastructure onto the Russian bulletproof hosting provider Proton66. A year later, we’re still tracking this cluster closely, and the group hasn’t slowed down. If anything, it has kept building.
