Kiteworks Urges Clients to Power Down Servers Amid Credible Imminent Cyberattack Warning

Global data‑exchange platform Kiteworks has issued an urgent directive to its entire customer base, asking them to shut down all operational servers immediately. The warning follows a “credible threat” communicated by law‑enforcement agencies, indicating that a coordinated cyber‑attack could strike at any moment. The advisory impacts dozens of enterprises that rely on Kiteworks to transfer large data sets securely over the internet.

In its notice, Kiteworks emphasized that the threat is “imminent” and that any unprotected infrastructure could suffer data loss, service outages, and substantial financial damage. The company confirmed close collaboration with authorities, stating that the intelligence received is verifiable and demands swift defensive action. Alongside the shutdown order, Kiteworks provided a detailed playbook covering threat‑vector monitoring, log preservation, and post‑incident forensic analysis.

Kiteworks executives highlighted that such disclosures are rare, but the severity of the risk necessitated full transparency. Clients are instructed to power off their servers, engage their security teams, and begin a coordinated re‑hardening process. The guidance also recommends reviewing backup strategies, isolating critical assets in air‑gapped environments, and preparing incident‑response teams for rapid deployment.

Cyber‑security analysts view the alert as a significant signal for the industry, suggesting that other cloud service providers may need to adopt similar proactive measures. Kiteworks assured customers that its 24/7 technical support desk is fully staffed to assist with the shutdown and subsequent restoration steps. The firm also pledged to release additional mitigations as more information becomes available. This decisive move underscores the growing importance of early warning systems and rapid response in defending against sophisticated cyber threats.
