Software company Kiteworks sent a warning to customers this week urging them to shut off the company’s platform over the weekend due to concerns over potential cyberattacks or intrusions. 

The email to customers, first reported by German news outlet Heise, recommends customers shut down their systems during a six-hour window on Saturday. 

In response to inquiries about the message, Frank Balonis, CISO at Kiteworks, told Recorded Future News that the company “received credible threat intelligence from federal intelligence authorities indicating that a threat actor may attempt to target some Kiteworks systems for customers.”

“Out of an abundance of caution, we notified customers directly and recommended a precautionary shutdown window while we and our law enforcement partners work through the matter,” Balonis said. 

“We are not aware of any compromise of Kiteworks systems, and this advisory is preventative rather than a response to a confirmed breach. All known vulnerabilities are addressed in our current release, 9.5.1, and we continue to recommend customers run the latest version."
