A country-point out action team originating from China has been connected to cyber attacks on dozens of corporations in Taiwan as portion of a suspected espionage marketing campaign.
The Microsoft Danger Intelligence workforce is monitoring the exercise below the title Flax Hurricane, which is also identified as Ethereal Panda.
“Flax Hurricane gains and maintains lengthy-time period accessibility to Taiwanese organizations’ networks with nominal use of malware, relying on equipment developed into the working technique, along with some ordinarily benign application to quietly keep on being in these networks,” the firm reported.
It more reported it hasn’t noticed the group weaponize the entry to conduct details-assortment and exfiltration. A majority of the targets include governing administration companies, instructional institutions, critical producing, and info technology businesses in Taiwan.

“Ethereal Panda functions largely focus on entities in the educational, technology, and telecommunications sectors in Taiwan,” CrowdStrike notes in its description of the hacker crew. “Ethereal Panda relies intensely on SoftEther VPN executables to keep entry to sufferer networks, but has also been noticed deploying the GodZilla web shell.”
The principal aim of the actor revolves all-around persistence, lateral movement, and credential obtain, with the actor using living-off-the-land (LotL) methods and arms-on keyboard action to recognize its ambitions.

A noteworthy factor of the attacks is the modification of the Sticky Keys behavior to start Endeavor Supervisor, enabling Flax Hurricane to conduct publish-exploitation on the compromised method.
“In conditions where by Flax Storm needs to transfer laterally to access other programs on the compromised network, the actor uses LOLBins, including Windows Remote Administration (WinRM) and WMIC,” the Windows maker stated.
The progress arrives three months immediately after Microsoft exposed one more China-linked actor named Volt Storm (aka Bronze Silhouette or Vanguard Panda), which has been noticed exclusively relying on LotL strategies to fly beneath the radar and exfiltrate details.
Though crossover of ways and infrastructure amid threat actors running out of China just isn’t unconventional, the findings paint the image of a regularly evolving risk landscape, with adversaries shifting their tradecraft to become additional selective in their follow-on operations.
