Malicious code in log-min (npm)

That module's top-level IIFE imports an opaque blob 'desKey' from the 'thedata' npm dependency, DES-decrypts it with the hardcoded password 'hydra', spawns a detached 'node' child process with piped stdin and ignored stdio, writes the decrypted code into the child's stdin, and unrefs the child so it survives the installer.

The executed bytes originate in a separate dependency ('thedata') and are not present in the log-min tarball, giving the author of that dependency arbitrary code execution on any machine that installs or imports log-min.
