SAM Hive Access via Avast Sandbox Component (PrettyPrague)
Detects access to the SAM registry hive or SAM-related LSA control keys initiated by a process associated with the Avast Sandbox component rather than LSASS or an administrative security tool. The PrettyPrague PoC abuses a vulnerability in Avast Sandbox to dump the SAM database and spawn a SYSTEM shell, so SAM hive reads originating from the sandbox component itself are anomalous.
