Alex Stamos, chief security officer at Cognition, explains how AI-enabled hacking tools are driving unprecedented waves of cyberattacks and reshaping the economics of cybersecurity, predicting a difficult transitional "dark age."

Cybersecurity is undergoing a profound transformation due to AI-enhanced hacking techniques, according to Alex Stamos, chief security officer at Cognition and a longtime cybersecurity expert. In a detailed discussion with The Verge, Stamos highlighted how AI tools have enabled attackers to automate the entire cyber "kill chain," allowing them to find and exploit software vulnerabilities in real time at an unprecedented scale. This innovation drastically increases the speed, range, and sophistication of cyberattacks against companies worldwide.

Stamos describes the current cybersecurity environment as reminiscent of the early, chaotic internet days in the 1990s, when online security protocols were immature and easily bypassed. Today, however, this “Wild West” scenario is vastly amplified by AI-powered tools that are now publicly accessible, such as the open-source ARTEX system linked to Chinese hacker groups. These tools dramatically lower the skill barrier, allowing a broader array of malicious actors to launch successful breaches against multi-billion-dollar firms. For example, recent attacks have compromised platforms providing AI services and triggered cascading breaches affecting thousands of companies.

The economic model of cyberattacks is also changing. Previously, a limited number of highly skilled hackers and state-sponsored teams conducted attacks, with a structured hierarchy of tools and operators. Now, AI is democratizing advanced hacking capabilities, making sophisticated exploits affordable and scalable for smaller groups and individual attackers. This shift has been compounded by technologies like Bitcoin, which facilitate anonymous monetization of cybercrime.

Stamos identifies major threats coming from various sources: North Korean groups focused on stealing cryptocurrency, and the Chinese "cottage industry" of contractors breaking into companies to resell information. Meanwhile, the defensive side remains challenged by high operational costs. Current AI models deployed for defensive security operations are expensive to run compared to the nearly zero marginal cost for attackers using widely available hardware and open models.

To counter this imbalance, Stamos advocates for innovation that reduces defense costs, including leveraging lighter AI models to process vast security logs and only escalating suspicious activity to more complex systems. He also recommends a fundamental shift from merely patching bugs to remodeling and rewriting legacy software, especially outdated code bases that harbor extensive vulnerabilities. For instance, rewriting large critical systems like the Linux kernel in safer programming languages such as Rust could yield long-term security gains.

Despite the daunting challenges, Stamos is cautiously optimistic. He foresees an unavoidable “dark age” period where attacks intensify and defenses struggle, but believes that a new era of improved security will emerge. In the long term, he expects median software to be AI-generated, using secure languages and tested extensively, thereby reducing vulnerabilities.

The cybersecurity industry, Stamos stresses, must rapidly adapt to this AI-driven reality, focusing on operational cost efficiency and holistic defense strategies beyond bug-fixing. The stakes are high, as the scale and severity of AI-powered cyberattacks continue to escalate, impacting global technology infrastructure and business operations.
