There are recent reports about security researchers using AI agents to access Anthropic’s internal systems. And they have sparked an important conversation about third-party software risk and the security gaps that can emerge even in sophisticated technology environments.

“There’s a certain irony in building some of the most advanced AI systems in the world and having researchers find a way in through ordinary enterprise software. It’s a reminder that even the smartest technology is only as secure as the architecture surrounding it.
“What makes this research interesting isn’t simply the reported speed of the AI agents. It’s their ability to identify potential attack paths across the trust relationships that connect enterprise systems. A vulnerability by itself tells us very little about the actual business risk. The important question is what an attacker can reach, what they can access, and how far they can go.
“Anthropic deserves credit for reporting that its monitoring detected some of the activity and for taking containment measures. But the real measure of remediation is independent verification that those attack paths are closed.
“We need to stop confusing a successful patch with a verified security outcome. Otherwise, we’re just closing the front door and hoping nobody discovered the spare key.”

“Cathedral’s agents got into Anthropic the same way attackers get into everyone else, through the vendors. By Anthropic’s account, days of direct attacks on its own software failed. The breach came when the agents pivoted to the commercial software-as-a-service (SaaS) tools running Anthropic’s sales, human resources, and IT operations, and Cathedral says its agents found exploitable weaknesses there in under 12 hours.
“Anthropic is about as well-defended as a company gets, and its crown jewels never moved, no model weights, no source code, no customer conversations with Claude. What got hit was the layer it bought instead of built, third-party software that tracks customers and manages staff, the kind of layer wired together with integration permissions nobody re-reviews. Security maturity is capped by the weakest vendor you integrate with, and no amount of in-house engineering changes that.”

“This is one of those stories that highlights the dark side of bug bounty programs. A well-executed bug bounty program can work incredibly well because it establishes clear rules of engagement, scope, expectations, and communication. This one sounds like an absolute disaster. Now we’re getting into a he-said, she-said argument over the severity of the vulnerabilities and how they were handled.
“What is particularly frustrating is seeing vulnerability research used as a marketing opportunity. When that happens, it starts to look less like the goal was finding vulnerabilities and getting them fixed, and more like the goal was being as sensational as possible in the claims being made against Anthropic.
“But I don’t want the controversy around Cathedral to distract from the vulnerabilities themselves, because there is a much bigger security lesson here. This shows the risk created by heavily interconnected software-as-a-service applications that are tied into multiple critical parts of an organization.
“That becomes exceedingly difficult for any CISO. At some point, you are outsourcing a portion of your security risk. You can get letters of attestation. You can review compliance reports. You can ask vendors about their security practices. But ultimately, you are trusting those vendors to properly secure infrastructure that may have significant access to your organization.
“It’s a very interesting story, and I’m disappointed in how some of this was released and communicated. But there are important lessons here. One is about what happens when bug bounty programs are poorly run or the relationship between researchers and vendors breaks down. The other is about the enormous amount of risk organizations inherit from SaaS applications and the vendors they trust with access to critical parts of their infrastructure.”
While it is nice to see companies like Anthropic get a taste of their own medicine, it shows what an arms race that AI has become. And I am afraid that this is an arms race that we’ll lose.
