PRC-Nexus is a threat actor designation used in the provided content for actors targeting the virtualization layer in VMware vSphere environments. The activity described focuses on VMware vCenter Server Appliance (VCSA) and ESXi hypervisors, with the objective of establishing long-term persistence. The content states these actors operate beneath the guest operating system, exploiting a visibility gap where traditional endpoint detection and response tools are ineffective. It further notes that compromise of the vCenter control plane can provide administrative control over managed ESXi hosts and virtual machines, creating a path to exfiltrate Tier-0 assets. The activity is discussed in the context of the BRICKSTORM backdoor and related malware activity. No additional aliases, sub-groups, or attribution details beyond the PRC-Nexus name are directly provided in the content.
