<![CDATA[Kiteworks Urges Customers to Shut Down Systems for 9 Hours Over Possible Cyber Attack]]>Kiteworks, formerly known as Accellion, has advised customers to take their systems offline for a precautionary nine-hour shutdown over the weekend. The guidance follows credible threat intelligence warning of a possible imminent cyber attack against the platform.

According to Frank Balonis, the company's Chief, Kiteworks received intelligence from federal authorities indicating that a threat actor may attempt to target certain Kiteworks systems. The shutdown is positioned as a precautionary measure rather than a response to a confirmed breach.

Key points for customers and defenders:

  • A nine-hour system shutdown was recommended over the weekend.
  • The warning stems from federal threat intelligence, not a confirmed compromise.
  • The advisory applies to some Kiteworks systems, per the company's statement.
  • The legacy Accellion brand is directly relevant here, given its history of high-profile exploitation.

Anyone running Kiteworks or inherited Accellion infrastructure should treat the window seriously, verify their exposure, and monitor vendor communications for further instructions before restoring service.
