AI Summary
CISA issued an urgent warning about 'FortiBleed,' a large-scale credential theft campaign targeting Fortinet FortiGate firewalls and VPNs — with 86,644 devices compromised, representing roughly half of all internet-accessible Fortinet appliances. The campaign is attributed to Russian-speaking threat actors and CISA is urging immediate remediation of affected devices.
