Kiteworks Advises Global Server Shutdown Amid Federal Intelligence Warning of Potential Zero-Day Attack
Kiteworks, a secure data exchange provider based in San Mateo, California, issued an urgent advisory to its global customers, recommending a temporary shutdown of self-managed servers. This unprecedented measure was taken after the company received credible threat intelligence from federal intelligence authorities regarding a potential imminent zero-day attack targeting Kiteworks systems. The advisory, issued on September 25, suggested a coordinated six-hour shutdown window for self-managed deployments, including those on-premises and in customer-managed AWS and Microsoft Azure environments. Kiteworks emphasized that this was a preventative action, stating there was no confirmed breach, exploitation, or specific vulnerability disclosed at the time. The company later lifted the shutdown recommendation on September 27, confirming that its own hosted systems were restored and operating normally, and advised customers to bring their systems back online.
