Running AI scanners internally costs money, dev time, and management buy in to actually fix the mountain of tech debt the scanners uncover. As you said there is no incentive for that
But for bad actors the cost of pointing an LLM at an exposed endpoint or reverse engineered binary has dropped to near zero. The attackers tooling just got exponentially cheaper and faster, while the enterprise defenders budget remained at zero.
There should be a way to donate your unused tokens on every cycle to open source like rounding up at the chekout!
I've seen multiple proprietary places now including a routine AI scan of their code because it's so cheap and they may as well use-up unused tokens at the end of the week.
I mean, it's literally zero because they already paid for CC for every developer. You can't get cheaper than that.
