What is MAL-2026-12803?
MAL-2026-12803 is a malicious package in shiftmarkets-sdk, published on 5 Aug 2026.
Official description
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.
What should I do about MAL-2026-12803?
