Trusted DesignA sophisticated Windows kernel-mode rootkit initially misidentified as Cobalt Strike Beacon operates from Ring 0 to compromise system security. The driver patches Event Tracing for Windows (ETW), employs Direct Kernel Object Manipulation (DKOM) to hide processes, hooks the NSI driver to conceal command-and-control ports, and manipulates Windows Filtering Platform to block security products. Its most distinctive feature is a covert control channel where commands are delivered through registry writes monitored by a kernel callback, bypassing network-based detection. The rootkit masquerades as a legitimate Microsoft service and minifilter driver, includes anti-sandbox checks via hypervisor time-stamp counter probing, and exposes over two dozen kernel primitives including arbitrary physical memory access, process injection, hardware input spoofing, and reflective PE loading. Infrastructure remains operational with C2 server at 43.160.247.24.
