AN0580: Analytic 0580
Detects suspicious registry modifications under `HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors\*\Driver`, DLL loads by `spoolsv.exe` of non-standard or unsigned modules, and abnormal usage of the `AddMonitor` API by non-installation processes. This pattern often indicates an attempt to persist a malicious DLL via the print monitor mechanism, particularly when correlated with creation of files in `C:\Windows\System32` not tied to known patches or installations.
Automated summary not available
Glexia publishes ATT&CK takes only after source-hash and schema validation. Until then, use the official MITRE definition below and the defensive relationship context on this page.

Object version and sync metadata
The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates.

Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
