About this tag
FortiBleed refers to an active credential-compromise campaign targeting exposed Fortinet FortiGate VPN appliances, not a newly disclosed CVE. The FBI and U.S. Secret Service issued a joint advisory warning that FortiBleed operations continue against internet-facing systems, leading to credential theft, account lockouts, and follow-on ransomware activity.

This tag collects WindowsForum coverage and discussion of the FortiBleed warning and related Fortinet hardening guidance.
