FortiGate Firewall Exploits Lead to Service Account Theft
🔒 Security researchers warn of a campaign abusing FortiGate Next-Generation Firewall appliances to extract service account credentials and network configuration files. Attackers exploited disclosed vulnerabilities (for example, CVE-2025-59718, CVE-2025-59719, CVE-2026-24858) or weak credentials to create persistent admin accounts and loosen firewall policies. Compromised service accounts were used to authenticate to Active Directory, enroll rogue workstations, and enable lateral movement prior to detection.
