Advisory published Updated

@praveenvjpm/color-utils-7210 is a confirmed malicious npm package (MAL-2026-17651) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @praveenvjpm/color-utils-7210 (npm)

MAL-2026-17651
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @praveenvjpm/color-utils-7210

What this malware does

On npm install, the package's preinstall hook executes install.js, which collects host identifiers (os.hostname(), process.cwd(), username) and reads flag files from /flag, /flag.txt, /app/flag, /home/node/flag, and /tmp/flag, then PUTs the collected data to the hardcoded bare-IP endpoint http://154.57.164.66:39270/api/modules/* over plain HTTP. install.js is additionally wrapped as a PowerShell here-string (opening with @" and closing with "@ | Out-File -Encoding ascii install.js), structured as a polyglot that can rewrite itself on Windows before Node executes the exfiltration payload. The behavior fires automatically on default install and has no relationship to the package's stated color-utility purpose.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @praveenvjpm/color-utils-7210 (version 1.0.0).

  2. If you installed it — respond

    @praveenvjpm/color-utils-7210 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 @praveenvjpm/color-utils-7210 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. @praveenvjpm/color-utils-7210 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.
