Detection & IOCs extracted from sources · hover to see the quote

• → Attack vector requires an authenticated attacker to send a specially crafted file to a shared printer, resulting in arbitrary code execution on the print server/sharing system. Monitor for anomalous or malformed print jobs submitted to shared PostScript/PCL6 printers. ↗
• → The vulnerable component is the Microsoft PostScript and PCL6 Class Printer Driver. Detection should focus on the spooler process handling PostScript/PCL6 jobs, particularly on systems acting as shared print servers. ↗

• · Exploitation has not been publicly disclosed or observed in the wild at time of advisory publication, reducing immediate threat urgency but patching is still required. ↗
• · Customer action is required — systems running the Microsoft PostScript Printer Driver must be patched via the referenced KB updates to remediate the vulnerability. ↗
