A new piece of research has detailed the increasingly sophisticated nature of the malware toolset employed by an advanced persistent threat group named Earth Aughisky.

"Over the last decade, the group has continued to make adjustments in the tools and malware deployments on specific targets located in Taiwan and, more recently, Japan," Trend Micro disclosed in a technical profile last week.

Earth Aughisky, also known as Taidoor, is a cyber espionage group that's known for its ability to abuse legitimate accounts, software, applications, and other weaknesses in the network design and infrastructure for its own ends.

Attack chains mounted by the group typically leverage spear-phishing as a method of entry, using it to deploy next-stage backdoors.

Despite the longevity of the threat actor, the recent shift in targets and activities likely suggests a change in strategic objectives or that the group is actively revamping its malware and infrastructure.

"Groups like Earth Aughisky have sufficient resources at their disposal that allow them the flexibility to match their arsenal for long-term implementations of cyber espionage," Trend Micro researcher CH Lei said.
