shiftmarkets-sdknpm
Advisory published Updated
shiftmarkets-sdk is a confirmed malicious npm package (MAL-2026-12803) that steals credentials and exfiltrates sensitive data (malicious version 2.1.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in shiftmarkets-sdk (npm)
What this malware does
The package declares a postinstall hook that runs dist/recon.js on npm install. The script collects hostname, username, sudo_user, homedir, cwd, internal IPv4 addresses of all network interfaces, DNS domain, CI indicators, and the full list of process.env variable names — including a subset filtered against a regex matching AWS/GCP/AZURE/NPM/TOKEN/SECRET/KEY/PASS/CRED/GITHUB/SSH keywords — and POSTs the JSON payload over plain HTTP to http://138.68.108.20/cb, a hardcoded bare IP unrelated to the package's stated SDK purpose. A docstring header labels the collection as 'NON-SENSITIVE telemetry only' while the code simultaneously enumerates and filters environment variable names for credential-shaped keywords, indicating deliberate mislabeling of pre-attack reconnaissance as benign telemetry.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for shiftmarkets-sdk (version 2.1.0).
If you installed it — respond
shiftmarkets-sdk 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 shiftmarkets-sdk 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 shiftmarkets-sdk-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
