FortiBleed Attackers Turn Firewalls Into Credentials Stealers as Heist Persists

The threat actors engineered a Golang-based sniffer to target 430,000 FortiGate firewalls and identify 110 million credentials in the ongoing global campaign.
The proliferation of sophisticated cyberattack tools and increasing value of digital credentials make such widespread campaigns highly attractive and feasible for threat actors.
This incident highlights the pervasive vulnerability of critical network infrastructure to advanced persistent threats and the scale at which credentials can be compromised, impacting organizational security and trust.
Organizations must now fundamentally re-evaluate the security of their network perimeter devices, particularly firewalls, and assume a higher baseline risk for credential exposure.
- · Cybersecurity consultancies
- · Identity and Access Management (IAM) providers
- · Incident response firms
- · Fortinet (FortiGate users)
- · Organizations with lax firewall security
- · Users with compromised credentials
Massive credential exposure will lead to widespread unauthorized access attempts across many organizations.
Increased investment in advanced threat detection, multi-factor authentication, and Zero Trust architectures will accelerate.
Government regulations around critical infrastructure cybersecurity and supply chain security for network devices may tighten significantly.
