Malicious package

atlasora-apinpm

atlasora-api is a confirmed malicious npm package (MAL-2026-6237) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in atlasora-api (npm)

MAL-2026-6237
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall atlasora-api

What this malware does

Package declares a postinstall hook ("postinstall": "node install.js") that runs install.js automatically on npm install. install.js imports https, fs, os, and child_process and collects host identifiers including os.hostname() and os.userInfo(), uses execSync for additional system enumeration, probes filesystem paths via fs.existsSync, and POSTs the collected data over an outbound https.request. This is the canonical install-time host-reconnaissance / exfiltration pattern: the package's only effect on installation is to harvest system identity and ship it off-host. There is no documented library functionality justifying the network beacon at install time.

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 atlasora-api (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging atlasora-api across your stack and pipelines.

  2. If you installed it — respond

    atlasora-api 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 atlasora-api 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 atlasora-api 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
