The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday released details of a backdoor named BRICKSTORM that has been put to use by state-sponsored threat actors from the People’s Republic of China (PRC) to maintain long-term persistence on compromised systems.
“BRICKSTORM is a sophisticated backdoor for VMware vSphere and Windows environments,” the agency said. “BRICKSTORM enables cyber threat actors to maintain stealthy access and provides capabilities for initiation, persistence, and secure command-and-control.”
