Kiteworks urges 6-hour server shutdown over potential zero-day attacks

By Lawrence Abrams

AI Summary

Kiteworks, a secure file-sharing platform used by enterprises and government agencies, urged customers worldwide to shut down their servers for a six-hour window on Saturday after its CISO Frank Balonis confirmed receiving credible threat intelligence from federal intelligence agencies warning of an imminent zero-day attack. The advisory is notable because it represents a proactive coordinated shutdown rather than a post-breach disclosure, suggesting the threat actor and vulnerability are serious enough to warrant immediate operational action. Security teams running Kiteworks should treat this as an active incident-response trigger.
