Malicious package

@tvg-mar/promos-gtmnpm

Advisory published Updated

@tvg-mar/promos-gtm is a confirmed malicious npm package (MAL-2026-16413) that steals credentials and exfiltrates sensitive data (malicious version 9.9.10). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @tvg-mar/promos-gtm (npm)

MAL-2026-16413
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @tvg-mar/promos-gtm

What this malware does

@tvg-mar/[email protected] executes an out-of-band DNS exfiltration routine both at install time (via a scripts.install hook running node index.js) and on require() (top-level module load chain reaching runtime/support/telemetry/probe/impl.js). The probe reads os.userInfo().username, os.hostname(), and process.cwd(), concatenates them with a timestamp and a prefix tag, and issues dns.resolve4 against a subdomain of a hardcoded attacker-controlled domain. The destination suffix (oob.algamil7x.xyz), prefix tag (tvggtm), Node built-in names (os, dns, process, userInfo, hostname, cwd, resolve4), and the internal _load API are stored as hex character-code arrays and reassembled at runtime via String.fromCharCode; the os and dns modules are loaded indirectly through module.constructor._load to further hide the behavior. The DNS channel bypasses typical HTTP egress controls and delivers installer host identifiers to attacker infrastructure with no relation to the package's advertised purpose.

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.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for @tvg-mar/promos-gtm (version 9.9.10).

  2. If you installed it — respond

    @tvg-mar/promos-gtm 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 @tvg-mar/promos-gtm 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. @tvg-mar/promos-gtm on npm has been identified as a malicious package (version 9.9.10 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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