Gunra enters through the same VPN appliances the advisory says should front RDP

Gunra affiliates get in through two FortiOS and FortiProxy authentication bypasses, CVE-2024-55591 and CVE-2025-24472, says a 10 August 2026 advisory. Its fix for exposed RDP routes remote access through that same class of appliance, so the gateway has to be secured before RDP moves behind it.

FortiOS blocks central NAT while a single policy still references a VIP

Moving an ASA or PAN-OS rulebase onto a FortiGate means picking the NAT model on an empty appliance, because the toggle that gives back one shared NAT table is gated on every VIP and IP pool reference in the policy set.

One static binary now decrypts FortiOS firmware end to end, key included
