What Zero-Day Response Should Be in the Post-Mythos Era

A Picus Security analysis examines the late-August attacks on PaperCut NG and PaperCut MF, where attackers exploited servers before PaperCut had issued a lasting fix. The incident had no assigned CVE ID and no public proof of concept at first, while an initial emergency patch was bypassed and a third release arrived on September 1. It highlights the need to validate exposure and compensating controls quickly when active exploitation begins before patching or conventional exploit testing is possible.
