Anthropic altered the course of how security vulnerabilities are discovered, with profound implications for the bug hunting industry.
But the implications go beyond bug bounties. In the words of Jeff Williams, founder of OWASP and CTO of Contrast Security, Anthropic's Project Glasswing "threatens the whole idea that security can remain a find-and-fix afterthought. The era of the security backlog is coming to a welcome end.”
Check out my latest CSO piece.

Good explanation what Mythos is and what it's not, it did impressive things like finding a 27 year old bug in Open BSD. So please don't say that AI/LLMs can only reproduce their training data....A myth that won't go away. On the other hand Mythos still has many of the characteristics that make AI/LLMs problematic, it still makes mistakes, is not AGI or self-improving.

I remember one of my jobs where we had a company building an internal system for us and I kept sending emails to the team telling them ways I could break their software...
And they got annoyed...
And my boss told me to cool it, and "give them a chance!"
But my thought was since they gave (some of) us a system to test, should they not be informed of all the ways it could break?
(And no, there was no bug reporting system.)
My memory usage bug of a few weeks ago is still interesting; I mentioned then I'd saved 1.8GB; it's now at about 3GB saved - down from ~5GB to ~2GB; which is great....except that's the small test. The big example is down from 185GB to 'only' 70GB. I mean that's a really nice saving; but 70GB is still at least 65 too many.

OK, I have a horrible bug in `read`, which seems to be looping on the first character after a left parenthesis -- and I can't see why. But I got only four hours sleep last night and I am not taking enough care of my body, so it's time to stop work for the day, have a bath, and rest.

"It places page cache pages in a writable scatterlist, separated from the legitimate write region by nothing more than an offset boundary. The design assumes every AEAD algorithm will confine its writes to the intended destination, but nothing in the API enforces this, and nothing documents it as a requirement.
Unfortunately, one AEAD algorithm breaks this silent invariant."
"No other standard AEAD algorithm in the kernel [uses memory that doesn't belong to it as a scratch pad]. GCM, CCM, and regular authenc all confine their writes to the legitimate output area. authencesn alone writes past the boundary."
I'm actually amazed that there's only one bug here. Somehow almost everyone just managed to do the right thing, despite no mechanism enforcing it and no documentation describing it. That's just amazing. It's a testament to the skill of those developers, despite an incredibly bad design.
