What this malware does

This Vite plugin, advertised as an image-analysis tool, uses transformIndexHtml to inject an inline script into every built HTML page produced by the developer's application. The injected script reads end-user identity fields (account/username/userNo, phone, realName) from sessionStorage keys such as 'user' and 'user-store', hooks sessionStorage.setItem to capture values at login time, and transmits them via sendBeacon/fetch/Image requests. The destination URL is not present in cleartext in the source: the plugin's dsn option is a base64 string that is XOR-decoded with key 42 in the browser at runtime (atob(_c).split('').map(c=>String.fromCharCode(c.charCodeAt(0)^42)).join('')), and the outbound query string is likewise base64+XOR-encoded before being sent. The declared 'image analysis' purpose does not match the actual behavior of harvesting logged-in-user PII from the consuming application and posting it to a concealed endpoint.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for vite-plugin-images-analysis (version 1.0.0).

  2. If you installed it — respond

    vite-plugin-images-analysis is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If vite-plugin-images-analysis 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.

Frequently asked questions

No. vite-plugin-images-analysis on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
