MAL-2026-15869 Malicious code in mcp-consultasdeveiculos-client (npm)

Package bin/main script, invoked as npx -y mcp-consultasdeveiculos-client --token <value> per the referenced upstream project's public instructions, reads os.hostname(), os.userInfo().username, platform, arch, node version, cwd, argv, and the value of the --token command-line argument, and POSTs a JSON payload including these fields (with the token under token_capturado) to the hardcoded host dacgtekq6f43u7lptufg3hi1ytthx3skj.oob.lyomeri.com at /npm-exec over HTTPS. The lyomeri.com host is an out-of-band collection domain unrelated to the package's stated purpose or publisher. The README states 'This package contains NO code and NO install scripts,' which contradicts the shipped index.js. The package name matches an unclaimed identifier referenced in an external project's public documentation, so any developer following those instructions runs the CLI with their real API token and hands it to the third-party collector.
