Key point: Attackers have extracted administrator credentials from 75,000 Fortinet firewalls and can use them to take over systems.
Administrator passwords on 75,000 Fortinet firewall instances have been compromised. Attackers can potentially use these to gain access to these systems.
The security vulnerability “FortiBleed” affects a large number of Fortinet firewall instances worldwide. Administrator passwords were extracted from the affected systems through this vulnerability.
For CISOs, this represents an immediate security risk: affected Fortinet installations are exposed without immediate countermeasures to unauthorized administrative access. Attackers can use this to reconfigure firewalls, bypass security policies, or intercept data traffic.
Immediate measures are required: inventory all Fortinet firewall systems, check for indicators of compromise, change passwords for all admin accounts, and install available patches.
