    Detects when the BeyondTrust remote support client process ('bomgar-scc.exe' or 'bomgar-scc') spawns a shell or a common reconnaissance/downloader tool. This behavior is a strong indicator of post-exploitation activity related to vulnerabilities like CVE-2026-1731, where an attacker gains code execution and begins to explore the compromised system.
