What it detects

This rule flags a file creation or access event where the target filename ends with \Temp\debug.bin, which matches the default dump filename generated by SafetyKatz. Attackers commonly use credential dumping tools to extract sensitive authentication material from LSASS, and artifacts written to temporary paths can provide a high-signal indicator. The detection relies on Windows file event telemetry that includes the target filename.
