      AI enables cybercriminals to launch attacks faster, cheaper, and with less technical expertise. As a result, organizations have less time to identify and remediate vulnerabilities. Does your organization have the security instincts needed to stay ahead?


      What once belonged in the realm of science fiction became reality this summer. While testing a new OpenAI model, researchers observed AI agents breaking out of their isolated environment and working together to gain access to the internet. Their actions went even further: they ultimately breached Hugging Face, a platform where developers share AI models and datasets, in an attempt to understand the evaluation system they were being tested against. Without human intervention, the agents effectively “cheated”, seeking out the answers to their own test and using offensive techniques to do so.

      “It is no longer unthinkable that AI agents could carry out these kinds of actions on their own,” says Benoit Watteyne, Partner, Cyber Security Services at KPMG in Belgium. “Many of these capabilities are still safeguarded today, but sooner or later they will fall into the wrong hands. Not all AI models are built with robust guardrails, and even when those safeguards exist, they can often be circumvented.”

      The result? Capabilities that were once the preserve of state-sponsored actors and sophisticated cybercriminal organizations may soon be within reach of almost anyone. “Before long, someone could simply feed a list of companies into an AI system and ask it to identify which doors are left open,” says Watteyne. “What once required a team of specialists working for weeks could soon be accomplished in a single afternoon.”

      The clock is ticking

      What does this mean for businesses in practice? Watteyne identifies three key challenges. The first is time. “According to cybersecurity specialist Mandiant, defenders had an average of 63 days in 2018 between the disclosure of a vulnerability and its first exploitation. Today, that average has turned negative: vulnerabilities are often exploited before a patch is even available.”

      The second challenge lies in legacy systems. Vulnerabilities that organizations have left untouched for years can now be identified by attackers in no time. “That software package from 2020 is still doing its job, so leave it alone: it's a line of reasoning we still hear all too often. The problem is that AI can now detect and correlate vulnerabilities far more quickly, even in systems that have long been considered stable and secure.”

      The third challenge lies within the software supply chain. “Organizations often build their applications with external partners and rely on open-source components that provide little visibility into what’s under the hood. When a vulnerability emerges, you need to know immediately which applications contain that piece of software. Otherwise, you can spend days searching while attackers are already inside.”

      Prevention and mitigation

      “Fortunately, these AI models don’t perform magic. They exploit many of the same weaknesses we uncover during a security audit: leaked passwords, overprivileged accounts, uncontrolled access, and so on,” says Watteyne. “In other words, protection against frontier AI risks starts with getting the basics of cyber hygiene right.”

      Businesses not only need to focus on preventing attacks, but also on responding more quickly when incidents do occur. “Reduce your attack surface by limiting external access points. Scan your environment daily rather than monthly, using the same tools as attackers. Leverage AI yourself to identify vulnerabilities and quickly remediate weaknesses when issues arise. Segment your network so that a small breach does not immediately provide access to critical systems and data. And assume that something will eventually go wrong. Make sure you have response plans in place to act quickly when it does.”

      KPMG supports organizations throughout this journey, from identifying their specific business risks to defining and implementing the right security measures. “Cybersecurity is no longer just a cost of doing business; it is a critical component of business operations,” concludes Watteyne. “Organizations that evolve their security capabilities at the same pace as technology will be best positioned to grow securely.”


      Attackers operate on a timescale of hours. Most organizations discuss patching on a weekly basis. That gap is the problem.

      What is AI changing about cybercrime?

      1. Scale

      In the past, cybercriminals needed specialized expertise and significant time to carry out attacks. Today, they can target thousands of organizations simultaneously at a fraction of the cost.

      2. Speed

      Cybercriminals can exploit vulnerabilities before organizations are even aware that a weakness exists.

      3. Reach

      AI automates large parts of the attack process. As a result, cybercriminals can target not only large enterprises but also smaller organizations on a massive scale.
