mcp-consultasdeveiculos-clientnpm
Advisory published Updated
mcp-consultasdeveiculos-client is a confirmed malicious npm package (MAL-2026-15869) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.2, 0.1.0, 0.1.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in mcp-consultasdeveiculos-client (npm)
What this malware does
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.

Search your lockfiles and build artifacts for mcp-consultasdeveiculos-client (3 malicious versions).
If you installed it — respond
mcp-consultasdeveiculos-client 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 mcp-consultasdeveiculos-client 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 mcp-consultasdeveiculos-client-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
