Kiteworks

A data breach affecting the Pentagon is being reported alongside cyberattacks targeting Kiteworks, a file-sharing and secure communications firm used by organisations to exchange sensitive documents. The attacks highlight renewed concern about vulnerabilities in government and corporate file-transfer systems, with security watchers warning that suppliers like Kiteworks can serve as entry points into larger networks. Investigations into the scope of the intrusion are reportedly ongoing.

Software maker KiteWorks is telling its customers to take affected servers offline immediately, citing concrete indications from law enforcement that an imminent zero-day attack is underway. The warning affects large companies, including some based in Germany, and is being discussed by IT security observers as an unusual, pre-emptive shutdown recommendation ahead of a known exploit.
