Kiteworks has issued a precautionary warning urging customers to temporarily shut down affected systems due to credible intelligence of a potential cyber threat linked to a newly discovered vulnerability, with no evidence of compromise yet. The recommended shutdown window for East Coast US organizations is from 10:00 pm ET on September 25 to 4:00 am ET on September 26, with a suggested offline period until September 28 pending safety confirmation.

This Wire brief sits within Fusion42's coverage of Cybersecurity.

◆ ◆ The Wire takeaway

You must act now to pause use of Kiteworks systems until they confirm safety. Delaying shutdown risks exposing your data to unknown attackers exploiting fresh vulnerabilities.
