CISA has issued an urgent advisory for organizations to harden their Fortinet environments after security researchers uncovered a "FortiBleed" campaign that compromised over 86,000 Fortinet firewall and VPN credentials. A Russian-speaking threat actor is believed to be behind the months-long campaign, targeting Western organizations, including a Turkish defense contractor working with NATO. Fortinet and CISA recommend immediate actions such as terminating all administrative and VPN sessions, resetting credentials, upgrading to the latest FortiGate versions, implementing multifactor authentication, and checking logs for suspicious activity.
