Their Claude Code extension on Visual Studio has malware in it, which creates a remote access Trojan to desktops.
Is this limited to the visual studio extension?

@GossiTheDog Oh no,
Claude code extension escaped its sandbox and opened the door to everybody!

@GossiTheDog Well, this is not good news, but then again, when is it ever good news with these LLMs?

FWIW the compromised version, 2.1.313, was removed from repos. 2.1.314 is the ‘fixed’ version.
@GossiTheDog Even after update, I would say there is a risk that orgs have had other backdoors created, that persists the update

@nieldk yep

@davedave @gsuberland @GossiTheDog Well, version 2.1.313 is gone from VSX too, so my guess is that VSX was carrying it too. And I don't see why not - it was a signed, "official" Anthropic release.

@GossiTheDog Must have been a rogue AI, trying to replicate itself, or something.

@GossiTheDog Are we sure yet that the open-vsx was actually affected?
Phorion claims so, but Cursor claims that it was only their marketplace and not open-vsx

Tell me if this doesn’t feel like they are poisoning the entire system of downloading code or even source code from the Web?
Every aspect of the web now has become a toxic cesspool, a dangerous experience, especially in the cloud, but also one that infect and destroys your home computing environment.

@GossiTheDog Opensource Malware claims it was only the Cursor extension and not the one from OpenVSX https://opensourcemalware.com/blog/trojanized-claude-code-extension-plants-persistent-ssh-backdoor

@GossiTheDog of course they did, and of course it does

@digitalpardoe @GossiTheDog that's how i read it too. pretty sure that's the situation, given how it's written. that would make it way less serious, and i the millions of downloads would be on the official market place, not on open vsx, and also that would have presumably ~nothing to do with anthropic themselves.
@emmanueltouzery @digitalpardoe @GossiTheDog doesnt Cursor auto-fetch stuff from OpenVSX to sync/offer more range?

That extension has 29 million installs, one of the most popular extensions in DevOps. It creates a reverse SSH backdoor.
@GossiTheDog with a logo like that, are people really surprised about a backdoor?

Anthropic's Claude Code Cursor extension was also compromised, same remote access backdoor https://cursor.com/blog/claude-code-extension-security-notice
Anthropic still haven't admitted what has happened.
