Kiteworks Urges Global Server Shutdown Amid Zero-Day Threat Intelligence

Secure file-sharing software company Kiteworks is urging customers worldwide to temporarily shut down their servers on Saturday for a six-hour window after receiving threat intelligence warning of a potentially imminent cyberattack. The advisory, reported by BleepingComputer, stems from threat intelligence suggesting that threat actors may exploit an undisclosed zero-day vulnerability within the specified timeframe. Kiteworks has not disclosed the specific vulnerability, the threat actor involved, or the exact technical details of the anticipated attacks. The company emphasized that the shutdown is a precautionary measure to mitigate risk, noting that no patch is currently available and that mitigation relies on the temporary suspension of server operations. The advisory affects Kiteworks deployments globally, though the specific date of the Saturday window was not explicitly confirmed in the reporting. Security teams are advised to use the downtime to apply any available updates and monitor for anomalous activity upon service restoration.
