Root cause of Equifax hack is web app vulnerability
Once again, the root cause of the Equifax hack is a web app vulnerability. These type of vulnerabilities have been around for over a decade but are still so relevant today. Each developer should be given the tools to avoid introducing these problems in the first place through training and real-time guidance while developing code.
Equifax said it discovered the breach on July 29. "Criminals exploited a U.S. website application vulnerability to gain access to certain files," the company said.

Matias Madou, Ph.D. is a security expert, researcher, and CTO and co-founder of Secure Code Warrior. Matias obtained his Ph.D. in Application Security from Ghent University, focusing on static analysis solutions. He later joined Fortify in the US, where he realized that it was insufficient to solely detect code problems without aiding developers in writing secure code. This inspired him to develop products that assist developers, alleviate the burden of security, and exceed customers' expectations. When he is not at his desk as part of Team Awesome, he enjoys being on stage presenting at conferences including RSA Conference, BlackHat and DefCon.

Secure Code Warrior is here for your organization to help you secure code across the entire software development lifecycle and create a culture in which cybersecurity is top of mind. Whether you’re an AppSec Manager, Developer, CISO, or anyone involved in security, we can help your organization reduce risks associated with insecure code.

AI Coding Assistants: A Guide to Security-Safe Navigation for the Next Generation of Developers
Large language models deliver irresistible advantages in speed and productivity, but they also introduce undeniable risks to the enterprise. Traditional security guardrails aren’t enough to control the deluge. Developers require precise, verified security skills to identify and prevent security flaws at the outset of the software development lifecycle.
Secure by Design: Defining Best Practices, Enabling Developers and Benchmarking Preventative Security Outcomes
In this research paper, Secure Code Warrior co-founders, Pieter Danhieux and Dr. Matias Madou, Ph.D., along with expert contributors, Chris Inglis, Former US National Cyber Director (now Strategic Advisor to Paladin Capital Group), and Devin Lynch, Senior Director, Paladin Global Institute, will reveal key findings from over twenty in-depth interviews with enterprise security leaders including CISOs, a VP of Application Security, and software security professionals.
