CVE-2026-81578: AI Agents Exploit PaperCut in 395-Org Campaign
A likely Russian-speaking threat actor deployed hundreds of AI agents—combining OpenAI Codex and DeepSeek models—to autonomously develop, test, and launch exploits against PaperCut NG/MF servers, compromising at least 440 instances across 395 organisations in 48 countries. The campaign demonstrated alarming operational tempo, moving from initial access to full domain administrator privilege in as little as seven minutes at one victim site, and compromising 11 organisations in just 26 seconds once the campaign was fully underway. This represents a significant escalation in AI-augmented offensive operations, where autonomous agents collapsed the traditional exploit-development lifecycle from days to hours.
