Anthropic's Claude Is Pumping Out Vulnerable Code, Cyber ... - Forbes
This is the online edition of The Wiretap newsletter, your weekly digest of cybersecurity, internet privacy and surveillance news. To get it in your inbox, subscribe here.NurPhoto via Getty ImagesIn March, developers at Ohio-based cybersecurity company TrustedSec were regularly using Anthropic’s premium Claude Opus model to speed up app development and generate attacks to test client defenses. But in recent weeks, they’ve stopped using it. Performance dropped so sharply in the weeks after the release of Opus 4.6 in early February that the model began introducing “serious defects and security issues,” says TrustedSec CEO and former NSA analyst Dave Kennedy. “Right now, from five weeks ago to today, the code quality is over 47.3% worse than when it was first released,” Kennedy tells Forbes. “It’s really bad, I mean unusably bad.” That figure is according to a tool he built to test Claude’s quality, which tracks code quality, bugs, security issues and whether it completes a coding job from start to finish without problems.The ultimate risk, he says, is that novice developers using Claude for coding won’t spot flaws, “introducing serious defects.” “It’s very alarming,” he says. Kennedy says Opus 4.7, the latest model, was “marginally better” but still not at the quality level of 4.6 when it was released.In recent weeks, scores of once-happy Anthropic customers have flocked to Reddit and X to vent similar frustrations. It’s not just programmers experiencing usability issues. An AI executive at chipmaker AMD wrote on Github that her team had seen Claude’s thinking become so “shallow” that it “cannot be trusted to perform complex engineering tasks.”Analyses from coding security company Veracode have also found that Claude models are writing less secure code than competitors. Over the last year, Veracode has been testing AI systems by asking them to complete 80 coding tasks. In 52% of those, Opus 4.7 included a vulnerability in the code. That’s up from 51% for Opus 4.1 and 50% for Claude Sonnet 4.5, a lower level, more cost-efficient model that doesn’t use up as much compute. OpenAI’s models perform notably better at around 30%.Jens Wessling, Veracode’s chief innovation officer, says the data backed up user claims of model degradation. Wessling believes models are being trained to write working code, “not to consistently apply the controls that make software secure.”“It reflects a real dynamic where faster, more capable models can still produce insecure output at ...
