AI’s Hacking Skills Are Approaching an ‘Inflection Point’

Vlad Ionescu and Ariel Herbert-Voss, cofounders of the cybersecurity startup RunSybil, were momentarily confused when their AI tool, Sybil, alerted them to a weakness in a customer’s systems last November.

Sybil uses a mix of different AI models—as well as a few proprietary technical tricks—to scan computer systems for issues that hackers might exploit, like an unpatched server or a misconfigured database.

In this case, Sybil flagged a problem with the customer’s deployment of federated GraphQL, a language used to specify how data is accessed over the web through application programming interfaces (APIs). The issue meant that the customer was inadvertently exposing confidential information.

What puzzled Ionescu and Herbert-Voss was that spotting the issue required a remarkably deep knowledge of several different systems and how those systems interact. RunSybil says it has since found the same problem with other deployments of GraphQL—before anybody else made ...
