Sophos Uncovers Extensive Chinese Espionage Campaign in Southeast Asia
Sophos, a leading cybersecurity firm, has released a report titled "Operation Crimson Palace," which details a sophisticated, nearly two-year espionage campaign targeting a high-level government organization in Southeast Asia. The investigation, which began in 2023, revealed three distinct clusters of cyber activity linked to well-known Chinese state-sponsored groups such as BackdoorDiplomacy, APT15, and APT41.
The campaign aimed to gather sensitive political, economic, and military intelligence using a variety of malware and tools. One notable find was a new persistence tool named PocoProxy. The three clusters, named Alpha, Bravo, and Charlie, showed different operational timelines and tactics but worked towards the same goal under a central directive.
Cluster Alpha, active from March to August 2023, deployed various malware for reconnaissance and disabling security measures. Cluster Bravo, active for a brief period in March 2023, focused on lateral movement within the network. Cluster Charlie, active from March 2023 to April 2024, concentrated on espionage and data exfiltration, using PocoProxy to communicate with command infrastructure.
Sophos emphasizes the importance of understanding the broader picture of such coordinated attacks to enhance defensive strategies. The report also highlights the ongoing nature of these threats, with at least one cluster still active.
