UNC 6201

Also known asUNC 6201

UNC6201 is a China-linked threat actor. According to Google Threat Intelligence Group (GTIG), UNC6201 exploited CVE-2026-22769 in Dell RecoverPoint for Virtual Machines since mid-2024. GTIG said the actor abused a hardcoded administrator password in Apache Tomcat used by the Dell backup product to obtain root-level access and deploy a newer version of the Brickstorm backdoor, which GTIG refers to as Grimbolt. Reported tradecraft includes creating temporary "ghost NICs" on virtual machines, using them for malicious activity, and then deleting them to complicate forensic investigation and evade defenders. The activity reflects targeting of backup and disaster recovery infrastructure, which operates with elevated privileges and can provide persistence, visibility into infrastructure and replicated data, and the ability to undermine restoration capabilities. Known alias in the provided content: unc_6201.
