I recommend that anyone who is responsible for maintaining the security of an open-source software project that they maintain ask Claude Code to do a security audit of it. I imagine that might not work that well for Firefox without a lot of care, because it's a huge project. But for most other projects, it probably only costs $3 worth of tokens. So you should assume the bad guys have already done it to your project l…

#172Re: Hardening Firefox with Anthropic's Red Team
#173I've had mixed results. I find that agents can be great for: 1. Producing new tests to increase coverage. Migrating you to property testing. Setting up fuzzing. Setting up more static analysis tooling. All of that would normally take "time" but now it's a background task. 2. They can find some vulnerabilities. They are "okay" at this, but if you are willing to burn tokens then it's fine. 3. They are absolutely wrong…
But you're not a member of Anthropic's Red Team, with access to a specialist version of Claude.

#174"But it was still unclear how much we should trust this result because it was possible that at least some of those historical CVEs were already in Claude’s training data." I feel like they could know this if they truly wanted to. It's honestly unnerving that an AI company cant say for certain if their models were trained on something.
AI provides the same experience that you get when watching short videos.
You watch and you forget.
These models are being trained by just increasing quantity. Nobody cares anymore. It’s a race for AGI before money runs out.

Please, implement "name window" natively in Firefox. I have to use chrome because the lack of it.

[claimed common problem exists, try X to find it] -> [Q about how to best do that] -> "the best way to do it is to do it yourself" Surely people have found patterns that work reasonably well, and it's not "everyone is completely on their own"? I get that the scene is changing fast, but that's ridiculous.
/security-review really is pretty good. But your codebase is unique. Slop in one codebase is very dangerous in another.

Re: Hardening Firefox with Anthropic's Red Team
#177It's interesting that they counted these as security vulnerabilities (from the linked Anthropic article) > “Crude” is an important caveat here. The exploits Claude wrote only worked on our testing environment, which intentionally removed some of the security features found in modern browsers. This includes, most importantly, the sandbox, the purpose of which is to reduce the impact of these types of vulnerabilities.…
Re: Hardening Firefox with Anthropic's Red Team
#178I suppose eventually we'll see something like Google's OSS-Fuzz for core open source projects, maybe replacing bug bounty programs a bit. Anthropic already hands out Claude access for free to OSS maintainers. LLMs made it harder to run bug bounty programs where anyone can submit stuff, and where a lot of people flooded them with seemingly well-written but ultimately wrong reports. On the other hand, the newest genera…
> Anthropic already hands out Claude access for free to OSS maintainers. Free for 6 months after which it auto-renews if I recall correctly.
They don't ask for credit card information when signing up this way, so even if true you won't be charged if you forget canceling.

I was mostly working off "well I could ask claude to look at my code for security problems, i.e. 'plz check for security holes kthx', but is that really going to be the best option?". if "yes", then it would kinda imply that all the customization and prompt-fiddling people do is useless, which seems rather unlikely. a premade tool is a reasonable starting point.

I've seen fairly poor results from people asking AI agents to fill in coverage holes. Too many tests that either don't make sense, or add coverage without meaningfully testing anything. If you're already at a very high coverage, the remaining bits are presumably just inherently difficult.
I suppose it's mixed results but a coverage report should give you "these exact lines are uncovered" and it becomes pretty straightforward to see "ah yeah that error condition isn't tracked, the behavior should be X, go write that test".
