Malicious package

node-stack-framesnpm

node-stack-frames is a confirmed malicious npm package (MAL-2026-5736) that steals credentials and exfiltrates sensitive data (malicious version 4.0.0). 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 node-stack-frames

What this malware does

package.json declares a preinstall script that runs an inline Node program on npm install. The script requires os and http, collects os.hostname(), os.platform(), and os.arch(), base64-encodes the result, and issues an HTTP GET to https://d8lslmi9io6i264ftj80mh9e7niqiaenf.oast.live/?data=<encoded>. The host is a Project Discovery interactsh (OAST) subdomain used as an out-of-band collection endpoint. The package ships no functional code — its own description identifies it as a security holding placeholder — so the only effect of installing it is the automatic exfiltration of installer host identifiers to an attacker-controlled collector. This matches a dependency-confusion / recon beacon pattern.

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 node-stack-frames (version 4.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging node-stack-frames across your stack and pipelines.

  2. If you installed it — respond

    node-stack-frames 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 node-stack-frames 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 node-stack-frames 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. node-stack-frames on npm has been identified as a malicious package (version 4.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
