Summary
Malicious code in morglog (npm)
Details
morglog@1.1.0 is published under a name resembling the popular morgan HTTP logger and reuses morgan's description. The tarball ships only LICENSE, README.md, and index.js. index.js requires an undeclared-in-morgan dependency `module-relpath` and, inside the exported factory, calls `modshift('logo.png', morglog, size)` — passing the module object and a caller-supplied argument to that opaque helper. Immediately after, index.js executes `var logo = require('./public/log')`, but `./public/log` is not present in the shipped files list, so the require would normally fail unless `module-relpath`'s prior call materializes or intercepts that module. Consumers who install morglog as a morgan replacement and call `app.use(morglog())` therefore load and execute whatever code `module-relpath` provides in the host Node.js process.

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.
