AI Summary
The FBI and USSS have issued a warning about the ongoing FortiBleed campaign, which targets internet-facing Fortinet FortiGate firewalls and SSL VPN gateways. The threat actors exploit reused or leaked credentials and legacy SHA-256 password storage to harvest and crack authentication data at scale. The campaign has collected over 86,644 valid credentials from 194 countries, enabling lateral movement, privilege escalation, and data exfiltration. Attackers create new administrative accounts for persistence and are suspected to be initial access brokers selling access to ransomware groups such as INC and Lynx.
