FortiBleed campaign used custom FortiGate sniffer to steal credentials
The FortiBleed campaign deployed custom packet sniffers on compromised FortiGate firewalls to harvest authentication credentials in transit — elevating the urgency for any organisation still running unpatched Fortinet edge devices.

Security firm SOCRadar says the large-scale FortiBleed campaign targeting Fortinet FortiGate devices used custom sniffers to harvest authentication secrets from compromised firewalls and steal credentials. [...]
Editorial Analysis
Fortinet devices are pervasive in European Mittelstand networks; credential harvesting at the firewall level means full network compromise may already have occurred silently.
Rotate all credentials that traversed FortiGate appliances and verify firmware is patched against all known FortiOS vulnerabilities.
Attackers installed credential-harvesting sniffers on Fortinet firewalls — assume compromise if devices were unpatched and rotate all network credentials.
