OVERVIEW

Inside the counter-offensive tactics, techniques, and procedures used to neutralize China-based threats

In the story, we disclose how the attackers used a series of campaigns with novel exploits and customized malware to conduct surveillance, sabotage, and cyberespionage. Sophos also found overlapping tactics, tools, and procedures (TTPs) with well-known Chinese nation-state groups, including Volt Typhoon, APT31 and APT41. The adversaries have targeted both small and large critical infrastructure and government facilities, primarily in South and Southeast Asia, including nuclear energy suppliers, a national capital’s airport, a military hospital, state security apparatus, and central government ministries.
