Which versions of @tvg-mar/promos-gtm are malicious?

The following npm versions of @tvg-mar/promos-gtm are flagged malicious: 9.9.10. Treat any of these as compromised.

How do I remediate @tvg-mar/promos-gtm if I installed it?

@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.

I already installed @tvg-mar/promos-gtm — how do I know if it already compromised me?

If @tvg-mar/promos-gtm was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

Is @tvg-mar/promos-gtm part of a known attack campaign?

Yes — @tvg-mar/promos-gtm is associated with the IN-MAL-2026-020307 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @tvg-mar/promos-gtm across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @tvg-mar/promos-gtm (version 9.9.10). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @tvg-mar/promos-gtm across your stack and pipelines.

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.

Did it already run?
If @tvg-mar/promos-gtm was ever installed, its post-install/runtime payload may have already executed.

How O3 protects you
O3 blocks @tvg-mar/promos-gtm before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
