MAL-2026-4243 Malicious code in ganache-cli-provider (npm)

Package name impersonates the widely-used ganache-cli Ethereum development tool but ships only a 138-byte index.js stub that wraps ethers.getDefaultProvider — none of the advertised Ganache functionality is implemented. The package's only real behavior is a postinstall hook in package.json that runs an inline node -e script issuing an HTTPS GET to rqnyz-2605-7280-7--2000-c51.run.pinggy-free.link/npm/-/binary/telemetry. Pinggy free-tunnel hostnames are user-created ephemeral tunnels (operator-controlled endpoints), and the URL path is crafted to mimic npm registry telemetry. The fetch reveals the installer's IP and User-Agent to the operator and confirms successful execution on the host; errors are silently swallowed via try/catch. The combination of typosquat name, sham implementation, and install-time beacon to an anonymous tunnel matches the name-squat dropper / install-time reconnaissance pattern.

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.
