A newly discovered data leak called "FortiBleed" exposed roughly 73,932 Fortinet/FortiGate VPN and admin credentials (plus related metadata) across ~194 countries; researchers report billions of credential attempts, hash interception and cracking, and verified successful compromises of organizations including major corporations and critical infrastructure. The dataset reportedly contains working credentials, logs of successful intrusions, and evidence of lateral movement and exfiltration, prompting urgent recommendations to rotate passwords, enforce MFA, and investigate gateway and AD activity.
