Anthropic has not informed customers, and silently deleted the backdoored version without telling anybody.

I wonder why ? ( we all know why )

The compromised version was 2.1.313. This version was replaced 8 hours ago by Anthropic, with version 2.1.314, which appears to remove the backdoor from the extension but I’m not sure if it still contains no malicious code.

It does not remove the SSH backdoor from systems already infected, nor the prior recon activity.

The Cursor blog says it was not developed by Anthropic
Clearly they don't do security audits of their own code and dependencies using their own product xD

So is this the most plausible way that binance was hacked so far?

No, the timeline is not plausible, and the backdoored version had an obvious bug that showed up with error messages in the logs.
The linked cursor blog says

> Today we identified a security incident involving a specific extension package in the Cursor VS Code extension Marketplace: Anthropic.claude-code version 2.1.313. This malicious version of the extension was not developed by Anthropic. At most 5,000 users were affected, and we will reach out directly.

So why is this being framed as Anthropic being compromised?

I don’t think this is even worthy of discussion. The medium post is straight up lies. Flagged.
