It seems like there is a genuine communication breakdown between management and engineering. Engineers know that there are vulnerabilities all over the place and that there have been for ages and that where the rubber hits the road every vulnerability does not represent a successful exploit by some nefarious actor.
Management can often treat cybersecurity like a black box that represents millions upon millions in liability. If Mythos represents an opportunity to bring management's understanding of the amount of "security vulnerability debt" everyone carries into the real world, it might be a good thing
I'm pretty impressed with regular Claude Code with Opus 4.7/4.8 in finding vulnerabilities in our code. Maybe 70% are false positives though. It's a lot of work to manually push back on the findings. Still worth it.
There's a lot of speculation that it is indeed a marketing plot and the model is just a step improvement over current capabilities... and the real reason they aren't releasing the model is they are compute constrained and cannot serve the model. To my knowledge there's no proof of this however, but given the fact that literally 60 days ago they made Mythos out to be the end of the world and last Friday they announced that they will release the model in a few weeks, I feel like it was indeed something along those lines (marketing ploy).
Or just control of supply and demand. If they can charge twice as much serving half as many customers, that leaves a lot of potential future customers leftover.
The week before they released Mythos to governments they had all their source code stolen. It's all about improving their image and creating propoganda.
Not so sure I would want a company that does not see any issues with mass surveillance of my country [1] to have access to critical infrastructure or its source code where I live.
That's someone who is confident enough to have an evidently successful enough career to be able to access Mythos in its currently-limited rollout and yet not take themselves terribly seriously online.
Realistically their opinion deserves to hold more weight than the median HN comment.

In other words it is equivalent to spending a million dollars on an audit by a software security consulting company

Is this just one giant marketing plot?

It wasn't "all their source code", it was the source code to Claude Code: not really any of their internal secret sauce, at least directly.

Got to say, Anthropic have hell of a marketing team.
I don't get how this is event front page of HN.
In the meantime, not everyone with actual access to the model are all that impressed.

“Cybersecurity weather person and award winning shitposter.” why are they someone we should pay attention to the opinion of?

I dunno, I trust the engineers working on Firefox or the Linux kernel more than some random pseudo-anonymous Mastodon account -
