Officials Warn About Expansive, Ongoing China Espionage Threat Riding on Brickstorm Malware

Chinese-linked hackers used Brickstorm malware to infiltrate VMware vSphere networks, maintaining access from April to September for espionage and potential sabotage, US and Canadian agencies said.

  • On Dec 4, U.S. and Canadian cybersecurity agencies said Chinese-linked hackers used Brickstorm to penetrate unnamed government and IT entities, targeting VMware vSphere environments, Broadcom's VMware confirmed awareness.
  • CrowdStrike and GTIG traced the campaign to at least 2022, with Chinese-linked state-backed hackers embedding for long-term access, disruption, and potential sabotage amid tradecraft evolution and multi-cloud targeting.
  • CISA's analysis, based on eight Brickstorm samples, showed implants Junction and GuestConduit written in Golang stole Active Directory credentials to reach VMware vCenter.
  • Dozens of U.S. organizations have been affected, researchers said, while vendors urged customers to apply patches and tighten operational security; Mr Liu Pengyu rejected the allegations.
  • Adam Meyers warned the campaign reflects expanded infrastructure and tooling, exploiting edge devices and appliances where detection is insufficient, blending espionage and IP theft in multi-cloud environments and posing long-term national-security and economic risks.
