Russian Initial Access Broker Behind FortiBleed Campaign

Russian Initial Access Broker Behind FortiBleed Campaign
SOCRadar says the FortiBleed campaign is a multi-vendor credential-harvesting operation run by a likely Russian-speaking initial access broker that has targeted more than 430,000 FortiGate firewalls and compromised over 110 million credentials. The attackers use tools like FortigateSniffer, Masscan, and Shodan to sniff authentication traffic, crack stolen data, and sell access, with activity spanning FortiGate, Sophos SSL-VPN, RDWeb, Citrix SSL-VPN, MSSQL, and Active Directory environments. #FortiBleed #FortigateSniffer #FortiGate #SOCRadar #CyberStrike
