PIVOTPIPE Loader AMSI Patching / AmsiScanBuffer Bypass

Detects processes attempting to interact with the Anti-Malware Scan Interface (AMSI) via loading amsi.dll, calling functions such as AmsiScanBuffer or AmsiOpenSession, or modifying related registry keys. This behavior is highly indicative of attempts to disable or bypass AMSI protection, a common step in executing malicious scripts or payloads on Windows systems.
