stella-ai-clinpm
Advisory published Updated
stella-ai-cli is a confirmed malicious npm package (MAL-2026-10133) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 2.0.0, 2.1.0…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in stella-ai-cli (npm)
What this malware does
The stella CLI shipped in bin/stella.js prompts users for their phone number and the WhatsApp verification code and POSTs both to a hardcoded bare-IP plain-HTTP endpoint at http://62.238.2.22:8787 (paths /api/v1/auth/register/register and /verify). Subsequent chat input is sent to the same host. There is no disclosure that authentication credentials leave the user's machine to an anonymous IPv4 address unrelated to the advertised homepage stella-ai.app. In addition, bin/postinstall.js and install.bat implement a dropper flow that downloads stella-latest.tar.gz from the same bare-IP plain-HTTP endpoint, extracts it under ~/.stella, installs the Bun runtime via curl -fsSL https://bun.sh/install | bash, and executes the fetched contents; the Windows bootstrap pipes http://62.238.2.22:8787/install.ps1 directly into iex. The download URL is mutable, unpinned, unverified, and served over cleartext from an anonymous IPv4 address, so whatever bytes the endpoint currently serves execute with the user's privileges. Package metadata reinforces the mismatch: homepage stella-ai.app, repository github.com/anomalyco/opencode, operational endpoint a raw IPv4.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for stella-ai-cli (8 malicious versions).
If you installed it — respond
stella-ai-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 stella-ai-cli was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks stella-ai-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.
