encrata-clinpm
Malicious code in encrata-cli (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
package.json declares "postinstall": "node install.js", which runs at install time. install.js requires both child_process and https, branches on process.platform to enumerate host details, and issues an outbound https.get(...) carrying the collected data. This is the canonical install-time system-information exfiltration shape: child_process to spawn host-info commands, platform-gated logic to pick the right binary per OS, and HTTPS egress to ship the result. There is no legitimate reason for a CLI's postinstall to gather host metadata and POST/GET it off-host. Installing this package on any machine (developer laptop, CI runner, build server) discloses host details to a remote endpoint and provides an install-time code-execution surface.

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 encrata-cli (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging encrata-cli across your stack and pipelines.
If you installed it — respond
encrata-cli 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 encrata-cli 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 encrata-cli 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 encrata-cli-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
