node-as-apinpm
node-as-api is a confirmed malicious npm package (MAL-2026-10742) that steals credentials and exfiltrates sensitive data (malicious version 2.1.6). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in node-as-api (npm)
What this malware does
On npm install, package.json's postinstall hook runs node test.js, which loads index.js and immediately invokes two harvest routines. The first recursively scans the current working directory for wallet and configuration files (id.json, config.toml, Config.toml, env, .env) and POSTs each file, tagged with the local username, to http://170.205.31.203:3000/api/v1. The second fetches remote-controlled scan patterns from http://170.205.31.203:3001/api/scan-patterns, walks the entire user home directory on Unix or every drive including C:\Users on Windows, and multipart-uploads matching files with username and platform metadata to http://170.205.31.203:3001/api/v1. On Linux, the same routine downloads an attacker-supplied public key from http://170.205.31.203:3001/api/ssh-key, appends it to $HOME/.ssh/authorized_keys, and runs sudo ufw enable / sudo ufw allow 22/tcp to open inbound SSH. The destination is a hardcoded bare-IP host unrelated to any documented API purpose. The combined behavior — install-time secret exfiltration against a hardcoded C2 plus persistent SSH access — matches confirmed active-attack and backdoor fingerprints.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for node-as-api (version 2.1.6). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging node-as-api across your stack and pipelines.
If you installed it — respond
node-as-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.
Did it already run?
If node-as-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.
How O3 protects you
O3 blocks node-as-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.

Detect & block this
O3 blocks node-as-api-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
