FortiBleed 2.0 Reveals Thousands of Fortinet VPN and Active Directory Credentials in Exposed Configurations
FortiBleed 2.0 exposes 40,573 cleartext credential records from Fortinet FortiGate configurations including VPN and
FortiBleed 2.0 investigation revealed 40,573 cleartext secret records extracted from 1,703 exposed FortiGate configuration files, including 37,076 local-user passwords, 1,576 Active Directory LDAP bind records, and administrator credentials. The compromised data links firewall access, VPN services, and internal identity systems across 1,689 host identifiers, though it is not a newly disclosed vulnerability but rather a follow-up analysis of configuration files mostly dated February 2026. Security teams are advised to terminate sessions, reset credentials, enforce MFA, update firmware, and audit logs for unauthorized access attempts.

The lesson from this incident
Full lessonOver 40,000 cleartext credentials — including local-user passwords, Active Directory LDAP bind records, and administrator accounts — were extracted from 1,703 publicly exposed FortiGate configuration files. The root failure was the exposure of device configuration files containing sensitive secrets in plaintext, meaning a single misconfiguration or unpatched vulnerability translated directly into mass credential compromise. This matters because the leaked data bridges firewall access, VPN services, and internal identity systems, giving attackers a near-complete pathway into corporate environments. Storing credentials in cleartext within configuration files violates basic security hygiene and amplifies the blast radius of any exposure event enormously.
What helps against this
How we list vendors
- Phishing-resistant MFA
A stolen password, or a user who taps Approve on a push prompt, is no longer enough to log in.
- Privileged access management (PAM)
Admin accounts stop being one stolen password away from control of everything.
- Encryption and key management
Stolen data stays unreadable, and the keys stay under your control.
