•updated Sep 17, 2026•0•0•5

This rule detects potential exploitation attempts against PaperCut servers by identifying high-frequency, consistent-interval network requests directed at PaperCut-specific URI patterns and ports, or associated with known vulnerability identifiers (CVE-2026-81578, CVE-2026-82078). The rule employs statistical analysis to identify potential automated scanning or exploitation activity, filtering out known geographic regions associated with lower-risk or irrelevant traffic.
