‼️🚨 BREAKING: 320,000 Fortinet firewall devices have been targeted in a campaign that has been dubbed 'FortiBleed'. Attackers were able to confirm 75,000 working credentials against the admin and SSL VPN interfaces. The victims include really big names like Samsung, Oracle, Spotify, Sony, and more. The data was first surfaced by researcher Volodymyr "Bob" Diachenko and analyzed by Hudson Rock and SOCRadar. The operation runs as a self-feeding loop. Attackers scan the internet for exposed Fortinet devices, then test each one against a curated list of passwords leaked from earlier Fortinet breaches and infostealer logs. Every successful login gets recorded into a verified database. They then turn each compromised box into a listening post, sniffing the traffic passing through the firewall to harvest fresh credentials, which go straight back into the scanner. The scale is large. The group ran an estimated 1.16 billion credential attempts against more than 320,000 FortiGate targets, plus 2.1 billion brute-force tries against 160,000 MSSQL servers. In the deeper intrusions they intercept SSL VPN authentication hashes, crack them on a dedicated 45-GPU cluster, and move into internal Active Directory. Diachenko confirmed full network compromises in Japan, Taiwan, Vietnam, Iraq, and Turkey, including a Turkish NATO defense contractor that had classified defense documents stolen. If you run Fortinet, act now: rotate every VPN and admin credential, enforce MFA on all external gateways, restrict management access to approved sources, segment internal networks, and audit gateway logs for unusual logins.
