Kiteworks Urges Customers to Shut Down Systems for 9 Hours Over Possible Cyber Attack

Telling every customer to power their servers off for nine hours over the weekend is not a normal advisory. Kiteworks did exactly that after what it calls credible threat intelligence from federal intelligence authorities about a possible zero-day — no CVE, no confirmed compromise, just a precautionary shutdown window and 9.5.1 as the latest patched build. Given Kiteworks is the former Accellion, the caution is easy to understand 😅
