Matilda Bailey brings a wealth of knowledge to the table regarding the security of our modern network infrastructure. As a specialist in next-gen solutions and wireless technology, she has watched the evolution of edge device security closely, particularly as it relates to cellular and next-gen networking. In this discussion, we explore the alarming impact of tens of thousands of harvested credentials, the rising role of AI in automating password spraying attacks, and the essential remediation steps organizations must take to safeguard their firewalls and VPNs against sophisticated campaigns like FortiBleed.
Given that over 86,000 sets of working credentials across 194 countries have been harvested in the FortiBleed campaign, how does this level of exposure shift our understanding of perimeter security?
This massive breach highlights a sobering reality: the network perimeter is only as strong as its weakest access point. Seeing 86,000 credentials compromised isn’t just a statistic; it represents tens of thousands of corporate gateways left wide open to malicious actors across nearly every corner of the globe. Many of these credentials were likely salvaged from older incidents, specifically tied to unpatched vulnerabilities like CVE-2026-24858 or the flaws addressed in late 2025, such as CVE-2025-59718. It proves that even when a vendor provides a fix, the delay in implementation creates a lingering shadow of risk that hackers are more than happy to exploit years down the line.
Fortinet mentioned that threat actors are now leveraging AI to automate target identification and password spraying. How is this technological shift changing the way administrators need to defend their firewalls and VPNs?
The use of AI-driven automation essentially means that bad actors can knock on every single digital door at once without ever getting tired. By using AI to streamline password spraying and find poorly protected edge devices, attackers are turning what used to be manual work into a high-speed assembly line of intrusion. This necessitates a shift toward more robust authentication methods because traditional passwords simply cannot stand up to the brute-force capabilities of modern algorithms. Administrators can no longer rely on obscurity or basic logins; they must embrace multi-factor authentication and restrict external management to specific, trusted hosts to shrink that massive attack surface.
For organizations currently navigating the aftermath of this campaign, what are the most critical steps beyond just changing passwords to ensure long-term resilience?
Simply rotating a password is a temporary fix for a much deeper problem; organizations must take immediate action to terminate all active admin and VPN sessions to clear out any latent intruders. Beyond that, it is vital to upgrade to software releases that support PBKDF2 hashing, which significantly strengthens how credentials are stored and protected against cracking. We also urge teams to meticulously review their logs for any unexpected admin access and check firewall configurations for unauthorized changes that might have been slipped in during the breach. Implementing multi-factor authentication across every single user account is no longer optional—it is the foundation of a modern, secure network.
What is your forecast for the security of edge devices as these automated, credential-based attacks continue to evolve?
I anticipate a significant move away from traditional credential-based access as the primary security layer for edge devices in the coming years. As we see more campaigns like FortiBleed, the industry will likely mandate hardware-backed authentication and zero-trust architectures as the standard rather than the exception. We will see more frequent, automated patching cycles becoming the norm because the window between a vulnerability being discovered and it being weaponized by AI is shrinking to almost zero. In the near future, if a device is visible on the public internet and relies solely on a username and password, it will almost certainly be considered compromised by default.
