AI Summary
The GoSerpent campaign is a sophisticated and evolving threat targeting government and diplomatic entities in Southeast Asia since at least 2021, with ongoing activity observed through 2026. The primary malware, GoSerpent, is a Go-based backdoor that enables remote access, SOCKS5 proxying, and deployment of additional tools for data collection and credential dumping. In 2026, attackers expanded their toolkit with Stowaway, a new Go-based RAT, and TmcLoader/TmcPayload, a stealthy two-stage payload used for exfiltrating data collected by earlier stages. The attack chain demonstrates high operational integration, using credential dumping tools like Mimikatz and QuarksDumpLocalHash to enable lateral movement and exfiltration of archived sensitive files via network shares.
