PaperCut NG/MF Zero-Day Actively Exploited, Emergency Patch Released
- Engineer — Act: PaperCut NG and MF print management software is under active zero-day exploitation with confirmed customer incidents; apply PaperCut’s emergency patch for v25/v26 immediately and isolate unpatched instances from the network until patched.
- SOC/IR — Act: Confirmed active exploitation means assume-breach posture for any PaperCut server in the estate; sweep PaperCut application logs for anomalous requests and lateral movement indicators since PaperCut servers have been used as initial-access footholds in prior ransomware campaigns.
- Leader — Act: Active zero-day with confirmed customer incidents in widely deployed enterprise print software; this week confirm whether your organization runs PaperCut NG or MF, verify emergency patching is underway, and prepare a brief for leadership if exposure is confirmed.
