FortiBleed Campaign Exploits Unchanged Passwords to Breach 30,000+ Fortinet Firewalls

The FortiBleed campaign demonstrates that attackers don't need sophisticated exploits—companies that fail to change default passwords on critical network devices remain dangerously exposed. Affecting major corporations from Accenture to Samsung, this breach of over 30,000 Fortinet firewalls highlights a critical gap between device deployment and security hygiene. Once compromised, firewalls become listening posts where attackers intercept additional credentials and launch cascading attacks, exponentially expanding the breach's scope and damage.
