Kiteworks issued an emergency advisory urging all customers to shut down their servers for six hours on September 26, 2026, after receiving credible law enforcement intelligence about an imminent zero-day exploitation threat. No active compromise has been confirmed, but the company is taking precautionary measures globally.
The shutdown order covers all Kiteworks systems worldwide, affecting thousands of customers across healthcare, technology, and government sectors. Kiteworks explicitly advised customers to act quickly even if their systems are not internet-accessible.
With ransomware gangs known to exploit zero-day vulnerabilities, the advisory creates immediate urgency for incident response and patch management services. The latest Kiteworks release, version 9.5.1, patches known vulnerabilities, giving security teams a concrete remediation step.
