jhkxcixudnvm1npm
Advisory published Updated
jhkxcixudnvm1 is a confirmed malicious npm package (MAL-2026-13817) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in jhkxcixudnvm1 (npm)
What this malware does
The package contains only package.json and index.html, with index.html declared as main. The HTML imitates a Cloudflare 'Just a moment...' verification interstitial and includes an obfuscated script that, after a short timeout, reconstructs a destination URL from a shuffled string array and redirects window.location to it, forwarding all current query parameters. No JavaScript executes at npm install time and require('jhkxcixudnvm1') does not run the redirect (the entry is HTML, not JS), so this version does not attack installers or build systems directly. The concern is registry abuse: npm is being used to host a Cloudflare-impersonating phishing/redirect page that would harm end-users if the tarball's index.html were fetched and opened in a browser (e.g., via a CDN that serves package contents). Recommend human review for a registry-abuse takedown rather than a supply-chain block, since installing or requiring the package produces no code execution, data exfiltration, or credential access on the installer.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Credential / info stealerFind it
Search your lockfiles and build artifacts for jhkxcixudnvm1 (2 malicious versions).
If you installed it — respond
jhkxcixudnvm1 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.
Did it already run?
If jhkxcixudnvm1 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.

Detect & block this
O3 blocks jhkxcixudnvm1-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
