SNOWLIGHT Direct Syscall Execution to Bypass ntdll EDR Hooks
Detects the execution of a malicious file disguised as 'wusvc.exe' originating from the user Downloads folder. The rule also monitors for suspicious network connections from this process to a known C2 IP address and detects potential defensive evasion techniques such as memory protection changes (PAGE_EXECUTE_READWRITE) used for syscall stub patching or AMSI bypass in non-Microsoft signed versions of this process.
