I found out my employer doesn’t have access to Mythos.

Mythos is not great btw. Running it over a bunch of code, it’s similar findings to tools from a few years ago. It’s marketing, essentially. Viral marketing as people doing the marketing are companies and governments.
It’s really good at finding vulns in vibe coded stuff from Claude.. because apparently AI must be both the cause and solution to all life’s problems, like beer.
@GossiTheDog mythos has found at least one critical vulnerability: the infosec industry is utterly vulnerable to hype, and extremely unlikely to examine the origins or methodology behind vulnerability disclosures that authorities (regardless of their poor reputation) claim are earth-shatteringly critical

@GossiTheDog @david_chisnall Yes, but beer is good, proven, and doesn’t burn the planet.

@zzt @GossiTheDog I'm pretty sure this vulnerability has been known for many years, though.

@zzt @GossiTheDog If this provides the industry with its "drink bleach" moment, I'm more than happy to watch the show.

@Standard_Phil @GossiTheDog absolutely, no points to anthropic for originality but full points for weaponizing the vulnerability to its fullest

@zzt @GossiTheDog Very fair point, they do deserve some credit here.

@GossiTheDog the marketing was so obvious even at the moment they first announced mythos.
"We have a super AI, it's the best at everything but we're not gonna let you see"
It's just like a preteen saying
"I have a supermodel girlfriend, she loves me more than anything but you can't meet her because she goes to another school" -

"I have a supermodel girlfriend, she loves me more than anything but you can't meet her because she goes to another school"@Kiloku @GossiTheDog My girlfriend is so hot and smart and loves me more than anything in the world and we have amazing sex together and she’s rich but you can’t see pictures of her because she’s shy and you can’t hear her beautiful voice because she lives in a different timezone and you can’t meet her because she’s Canadian. But she’s the best girlfriend ever!!!1
Now please believe me because it’s true.

@GossiTheDog@cyberplace.social @Standard_Phil@infosec.exchange @zzt@mas.to Mythos did find that recent ActivityPub vulnerability which is interesting. I’m not trying to shill it or anything I just think it’s interesting

@GossiTheDog My first hot take to “We are not releasing Mythos because it’s too good” was that they were hiding something. Or they needed to convince large companies that it was sooooo good that they better pony up. “You’ve never had coke this pure, not sure it’s safe to sell it to you.”

@GossiTheDog Can you run it on my honeypots to see if it finds anything worthwhile?
(Basically, any repo there that has "honey" or "pot" in the name.)

@bplein @GossiTheDog CISOs suched it up like no tomorrow. Every day I have to listen my bosses how utterly powerful Mythos is and we need some AI tool to counter it.
On the other hand they're surprised that all sorts of low level shit walks through our perimeter. I have to keep repeating we need zero-trust but nothing gets done.
