Overview
- CISA, NSA and the Canadian Centre analyzed eight Brickstorm samples from victim networks and confirmed targeting of VMware vSphere and vCenter appliances.
- One investigated intrusion showed persistence from April 2024 through early September 2025 after lateral movement from a DMZ web server to an internal vCenter server.
- The backdoor uses layered encryption over HTTPS and WebSockets with nested TLS, a SOCKS proxy and DNS-over-HTTPS, plus a self‑monitoring function to re‑install if disrupted.
- Officials and researchers report dozens of U.S. victims across government, IT, legal, SaaS and manufacturing, with Google estimating average dwell times near 13 months.
- CrowdStrike links the activity to a China‑nexus group it calls Warp Panda and notes additional Go‑based implants (Junction and GuestConduit) and cloud data theft, while agencies provide IoCs, YARA and Sigma rules, urge blocking unauthorized DoH, network segmentation and reporting of detections.
