Kiteworks, a secure file-sharing software provider, urges customers to temporarily shut down affected servers for several hours as a precaution after receiving threat intelligence suggesting a possible imminent cyberattack. The company tells customers the action should be taken during a specific weekend window to reduce exposure while the threat is assessed.

Different outlets report slightly different shutdown durations. Bleeping Computer says Kiteworks asks for a six-hour server shutdown, while The Hacker News reports a nine-hour shutdown request. Both accounts attribute the warning to “credible” threat intelligence received from federal or intelligence authorities, with Kiteworks warning that a threat actor may target some Kiteworks systems.

The reports frame the guidance as a protective measure rather than confirmation of an active breach. They also note that customers are expected to follow Kiteworks’ instructions and coordinate the shutdown period to match the company’s recommended timeframe, with the exact length varying by outlet’s account of the advisory.
