ThreatLabz Reports Mustang Panda-Linked PlugX Campaign Targeting Persian Gulf

Summary
ThreatLabz reports a March 1, 2026 campaign targeting Persian Gulf countries with Arabic missile-attack lures and LNK/CHM droppers delivering PlugX. It assesses China-nexus attribution with high confidence and Mustang Panda linkage with medium confidence.
Key points
