This is just hype. The marketing hype of these models has focused a huge amount of human effort on looking for vulnerabilities that we could have found before if CTOs could have been convinced that it was worth the time and resource investment to go looking for them.
We now have an industry full of executives who believe they will be the ones held responsible if they don't quickly respond to this "new threat" and so now the engineers who should have been given the time to address technical debt and look for security issues in their products years ago, actually have the remit from the suits to do so.
Any time one of these snake-oil companies tells you that their model found hundreds of security issues in a project, just realise that what it actually did is spit out thousands of useless pages of nonsense that a team of real engineers had to check, and in checking all of the nonsense they realised that hold on a minute, yes this particular function does have a vulnerability. The AI is just giving us permission to look, by pointing its sixth finger at every other line of code.
