FamousSparrow's SparroWocky Backdoor Targets Latin American Governments
The China-linked espionage group FamousSparrow has been conducting a sustained campaign against government organizations across Latin America using their new SparroWocky backdoor malware. From mid-2025 through 2026, the group targeted organizations in Argentina, Ecuador, Guatemala, Honduras, Panama, Peru, Puerto Rico, and Venezuela, replacing their previous SparrowDoor backdoor with this more advanced C++ malware. SparroWocky features sophisticated anti-analysis capabilities, modular architecture, and comprehensive data collection functions including screenshot capture, file manipulation, and proxy operations. The attacks aimed to gather intelligence on Latin American governments' responses to increasing U.S. pressure on Chinese economic interests, demonstrating China's strategic focus on regional geopolitical intelligence gathering. This campaign highlights the evolution of Chinese state-sponsored cyber espionage capabilities and their expanding focus on Latin American targets amid growing geopolitical tensions. The sophisticated evasion techniques and sustained operations demonstrate the increasing threat posed by well-resourced nation-state actors to regional government infrastructure and diplomatic communications.
