- description
- In this SentinelOne Labs investigation, researchers track a sophisticated China-linked threat actor relentlessly targeting high-value entities across multiple sectors. The report uncovers their evasive TTPs, custom malware tooling, and persistent intrusion attempts, providing critical IOCs (Indicators of Compromise) and defensive recommendations. A must-read for threat hunters and security teams defending against advanced persistent threats (APTs).
