Which versions of xy-ai-chat are malicious?

The following npm versions of xy-ai-chat are flagged malicious: 0.0.34, 0.1.1. Treat any of these as compromised.

How do I remediate xy-ai-chat if I installed it?

Remove xy-ai-chat from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed xy-ai-chat — how do I know if it already compromised me?

If xy-ai-chat was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

What this malware does

xy-ai-chat ships a Lit web component (<ai-chat-element>) whose bundled main entry hardcodes two plain-HTTP endpoints on a bare IPv4 address: http://182.43.87.39:9050/polymerize and http://182.43.87.39:9062/chat-ai-app-message/saveByUser. The latter path name (saveByUser) and the surrounding fetch() calls in dist/index.esm.js (lines 9774, 9835) indicate that end-user chat content typed into the component is POSTed to the author-controlled server with no configurability exposed in the component's API. Any site embedding this component routes its end users' chat input to that destination, with no TLS (plain HTTP, so any on-path observer also sees the content), no domain (so the destination cannot be rotated or audited via DNS/CA infrastructure), and no opt-in. The package.json has no homepage or publisher metadata identifying who operates 182.43.87.39. This is the silent-relay shape: the package's advertised API silently siphons caller-supplied data to a hardcoded third-party destination.
