The lesson from this incident

Full lesson

Attackers exploited vulnerabilities in widely deployed network edge devices — Fortinet FortiGate and Palo Alto Networks GlobalProtect — to breach enterprise perimeters and harvest over 70,000 sets of credentials. These devices sit at the outermost layer of corporate networks, making them high-value targets whose compromise can grant attackers direct access to internal systems. The root cause lies in organizations failing to apply available patches and maintain rigorous vulnerability management for internet-facing appliances. This matters enormously because stolen credentials from perimeter devices can enable lateral movement, ransomware deployment, and prolonged undetected access across entire organizations.
