Composite behavior indicating remote lateral movement over SMB followed by service-based execution of a staged payload delivered through mshta invoking msiexec from remote infrastructure. The sequence combines IPC$ share access, SAMR and SVCCTL RPC binding, service control pipe interaction, and remote command execution consistent with administrative service creation or modification to execute a downloaded installer. This pattern is strongly associated with hands-on-keyboard intrusion activity and automated lateral propagation frameworks leveraging Windows service execution for payload deployment.

Identifies HTTPS requests targeting the /fetch endpoint. This pattern is commonly associated with automated endpoint discovery, scripted resource retrieval attempts, or reconnaissance activity against applications exposing fetch-style API routes.
