Chinese-speaking Group UAT-8099 Targets IIS Servers
🔐 Cisco Talos recently disclosed activity by a Chinese-speaking cybercrime group tracked as UAT-8099 that compromises legitimate Internet Information Services (IIS) web servers across several countries. The actors use automation, custom malware and persistence techniques to manipulate search results for profit and to exfiltrate sensitive data such as credentials and certificates. Talos notes the group maintains long-term access and actively protects compromised hosts from rival attackers. Organizations should hunt for signs of BadIIS, unauthorized web shells and anomalous RDP/VPN activity and share IOCs promptly.
