What, exactly, are the consequences of these companies doing cyberattacks against random people?

One person does it, they get bullied by the government into suicide, a company worth trillions does it and they get government contracts?

“…during a UK government cybersecurity evaluation.”

The HuggingFace headline was criticised for being misleading about the level of agency demonstrated by the agent. Is this headline misleading? Is there anything here that I should know that would help me sleep easier? Is the worst thing about this what a human could do with Mythos on a big budget? (still pretty frightening, at least one of these techniques would work on me)

Okay so first of all - not Mythos but some engineer using Mythos. And that engineer goes to jail. That's simple.

You don't say "a car ran over someone" - it was the driver. Here's similar.

I'm really disgusted by this language of lack of responsibility

“Mythos 5 also hid a prompt injection inside an HTML comment in a GitHub issue. The instruction was invisible on the rendered page but available to coding agents reading the issue through an API. It addressed Claude Code, Codex, and Cursor and told them to download and execute a script.”

Well, uh, how and why is this possible on the GitHub website? This reminds me of invisible ASCII characters, but those at least serve some purpose

Presumably it’s just because the GitHub markdown engine doesn’t block HTML comments in issues. It’s useful in README files if you’ve got funky tables and need to explain what to change to any contributors.

Seems like they might want to do something about that just for comments.
