PlushDaemon
Intelligence Profile
PlushDaemon is a China-aligned APT group that has conducted cyberespionage operations against targets in China, Taiwan, Hong Kong, South Korea, the United States, and New Zealand. They executed a supply chain attack on the South Korean VPN provider IPany, compromising its installer to deploy the SlowStepper backdoor, which features a toolkit of over 30 components. PlushDaemon primarily gains initial access by hijacking legitimate updates of Chinese applications and has also exploited vulnerabilities in legitimate web servers. Additionally, they have utilized the Visual Studio command line utility regcap.exe to side-load a malicious DLL named lregdll.dll.
Threat Analysis

The group's espionage-oriented operations suggest a state-sponsored or state-aligned mandate, typically focused on stealing intellectual property, government secrets, or military intelligence. Targets are usually selected for strategic value rather than financial gain.
Classified as an advanced threat actor, PlushDaemon likely develops or acquires zero-day exploits, employs custom malware toolchains, and demonstrates long-term persistence capabilities — hallmarks of a well-resourced operation consistent with nation-state backing.
