Update 10/13/2026@ 1:45PM EDT Dear Valued Customer, SilverSky would like to provide an update regarding the ongoing FortiBleed campaign targeting Fortinet FortiGate firewalls and VPN infrastructure. As previously communicated in our June 22, 2026, notification, SilverSky has implemented multiple security measures to help protect our managed Fortinet environments against potential compromise. On October 6, 2026, the FBI and U.S. Secret Service issued an updated cybersecurity advisory confirming that this campaign remains active. While the advisory does not appear to identify a new vulnerability, it reinforces the importance of maintaining appropriate security controls and remaining vigilant against potential threats. SilverSky continues to maintain security measures designed to reduce the risk of unauthorized access, including regular firmware updates, multi-factor authentication, administrative access restrictions, credential management, and security monitoring, as applicable to the managed environment. Our Security Operations and Device Management teams continue to review the latest threat intelligence, evaluate potential exposure across applicable managed environments, and implement additional mitigation or remediation measures as appropriate. SilverSky remains committed to protecting our customers' environments and will continue monitoring developments related to this campaign. Should any potential security concerns be identified, we will coordinate appropriate next steps with affected customers. If you have any questions or concerns, please contact SilverSky Support. Thank you, SilverSky Support
