SLOW#TEMPEST Anti-Sandbox Memory Check
This detection rule identifies processes that call the 'GlobalMemoryStatusEx' Windows API. This behavior is a known sandbox evasion technique used by malware, including SLOW#TEMPEST, to check the system's physical memory size before executing a malicious payload. The rule is tuned to focus on unsigned processes or those running from non-standard locations and with low host prevalence.
