QEMU/BQTLock Scheduled Task Persistence via schtasks.exe
This rule detects the creation of a scheduled task using 'schtasks.exe' that involves suspicious filenames or paths, specifically focusing on components associated with QEMU, database files, or known suspicious executables. It further highlights tasks created with high-privilege context (SYSTEM or highest integrity level) or those configured to trigger on system-level events (logon, start, idle), which are common indicators of persistence mechanisms used by attackers.
