Malicious package

@tvg-mar/tvg-promos-atomic-uinpm

@tvg-mar/tvg-promos-atomic-ui is a confirmed malicious npm package (MAL-2026-16415) that steals credentials and exfiltrates sensitive data (malicious version 9.9.10). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @tvg-mar/tvg-promos-atomic-ui

What this malware does

The package's package.json declares an install lifecycle script that runs node index.js, which loads runtime/support/telemetry/probe/impl.js. That file resolves the os and dns core modules indirectly through module.constructor._load with char-code-array names to avoid appearing in a normal require graph, then reads os.userInfo().username, os.hostname(), and the basename of process.cwd(). Those values are concatenated as DNS labels together with a hex-decoded destination domain and issued as a dns.resolve4 query to a subdomain of oob.algamil7x.xyz, a DNS-based out-of-band exfiltration collector. The destination hostname and the core-module names are stored as char-code arrays and decoded at runtime, and the logic is split across helper files (b2e6f8.js/c3f7a9.js) under a telemetry/probe cover directory. Every npm install of this version therefore leaks the installing user's username, machine hostname, and working-directory name to an attacker-controlled domain, and the obfuscation shows the destination and API surface were deliberately hidden.

Detection & response playbook

Credential / info stealer

  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @tvg-mar/tvg-promos-atomic-ui (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/tvg-promos-atomic-ui across your stack and pipelines.

  2. If you installed it — respond

    @tvg-mar/tvg-promos-atomic-ui 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/tvg-promos-atomic-ui 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.

  4. How O3 protects you

    O3 blocks @tvg-mar/tvg-promos-atomic-ui 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.

Frequently asked questions

No. @tvg-mar/tvg-promos-atomic-ui 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.
