FortiBleed campaign used custom FortiGate sniffer to steal credentials
SOCRadar says the FortiBleed campaign targeted more than 430,000 FortiGate firewalls and used a custom tool called FortigateSniffer to capture authentication traffic and steal credentials from compromised devices. The attackers allegedly abused FortiOS diagnostics, processed captured traffic with SNIFTRAN and a PCAP analysis toolkit, and used Hashcat on GPU clusters to crack hashes and extract secrets. #FortiBleed #FortigateSniffer #FortiGate #SNIFTRAN #Hashcat #FortiOS
