NegativeGlimmer is a China-aligned threat actor involved in cyber espionage activity. ESET reported the group compromising governmental entities in Cambodia and Panama, as well as an AI and robotics company in South Korea. Reporting linked the South Korean targeting to Beijing’s interest in strategic technologies under the Made in China 2025 policy. ESET also reported that in December 2025 the group targeted a governmental organization in Panama using a spear-phishing and DLL side-loading infection chain to deploy a downloader that installed AdaptixC2 and displayed a decoy document. Later iterations observed in January 2026 in Cambodia and South Korea replaced AdaptixC2 with Cobalt Strike. The group is believed to share some level of overlap with TGR-STA-1030, which Palo Alto Networks Unit 42 documented as having breached at least 70 government and critical infrastructure organizations across 37 countries over the past year. Known alias in the provided content: negativeglimmer.
