Quick answer
In the FortiBleed campaign, cybercriminals exploited a vulnerability in Fortinet FortiGate by deploying custom sniffers to steal authentication credentials and tokens.
SOCRadar has published a report on a large-scale cyberattack dubbed FortiBleed. During the campaign, attackers exploited a vulnerability in Fortinet FortiGate firewalls, using specialized tools to intercept authentication data.
The attack involves deploying custom sniffers that analyze network traffic passing through vulnerable devices. This allows attackers to collect credentials, access tokens, and other sensitive information required for unauthorized access to corporate networks.
Experts note that such attacks pose a serious threat to organizations, especially amid the rise of remote work and cloud service usage. Compromising firewalls can lead to large-scale data breaches and disruptions to critical systems.
To minimize risks, SOCRadar recommends that companies promptly install security patches released by Fortinet and enhance network traffic monitoring. Special attention should be given to monitoring suspicious activity and restricting access to device administrative panels.
