For Mythos, for example, Anthropic doesn't tell us the number of false positives their tool returns, i.e. the number of times their tool says that something is a vulnerability and it ends up not being. My security expert collaborators tell me that this is one of the most important metrics by which security tools are judged, because it tells you the difference between a useful tool and a useless one that engineers won't use.
Anthropic also claims that Mythos can replace security experts. It's one thing to claim that you've built a useful tool, another to claim that you can replace experts. Some security experts have even said that it's dishonest to say your tool is superior to security experts because it found bugs in old codebases and we don't know how often people audit them for bugs and fix them. Again a misleading claim that is repeated by those outside of the company.
Another thing that I find funny is that Anthropic is making all these claims about security while they themselves couldn't stop their own source code from leaking. And from analyzing that code, people have seen how things are done now with "vibe coding" using Claude. Even things that can be done simply are done with brute force, i.e. trying all possible scenarios before arriving at an answer or solution.
How much computational power does it take to find any of these vulnerabilities Anthropic says they found? How much money would someone have to pay to use their tool vs bonafide experts?
A lot of security and safety is about processes, checks, clear people in charge of clear things, and clear access limits. That goes out the window with these “agents. It becomes harder to identify where things went wrong, or what types of tests you need to do to check for vulnerabilities and who is in charge of which issue.
Some experienced software engineers talked about how it's easy to just press “accept” of the buggy code that you see generated by Claude. So the question is, what about the new vulnerabilities created by using these “agents”? We’ve seen so many examples of issues, like people wiping out their entire production data.
