The FBI and Secret Service have issued a warning to Fortigate administrators about ongoing attacks targeting their systems, specifically mentioning the 'FortiBleed' vulnerability. This alert comes as many organizations have yet to fully secure their Fortigate devices against this threat, which could allow attackers to gain unauthorized access. The agencies emphasize the importance of immediate action to patch vulnerable systems to prevent potential breaches. Failure to address this issue could result in significant security risks for organizations relying on these devices. As the threat remains active, administrators are urged to take this warning seriously and implement necessary updates promptly.
