A sophisticated espionage campaign attributed to UNC6508, a China-nexus threat actor, targeted North American academic, medical, and military research institutions for over a year. The adversary exploited REDCap servers, deployed custom INFINITERED malware to harvest credentials, and maintained persistent access through trojanized legitimate files that survived software upgrades. After remaining undetected for more than a year, the threat actor pivoted to administrative accounts and created malicious content compliance rules to silently exfiltrate emails containing defense intelligence, Indo-Pacific command operations, artificial intelligence research, uncrewed vehicle systems, cyber programs, and medical research data. The operation employed sophisticated techniques including obfuscation networks routing through US-based infrastructure, compromised routers, and dedicated exfiltration accounts, demonstrating advanced operational security aligned with strategic intelligence collection requirements.
