AI-summarised brief · reviewed before publication
Kiteworks, formerly Accellion, has advised all customers to shut down their systems for a nine‑hour window over the weekend after receiving credible threat intelligence from federal authorities about a potential cyber attack. The company confirmed no evidence of compromise and emphasized the shutdown is precautionary. It urged users to apply its latest patch, version 9.5.1, which addresses all known vulnerabilities. Subsidiaries such as Zivver, DRACOON, and others are unaffected. The advisory was first reported by German outlet Heise.
