Malicious code in cspell-esm (npm)
Details
--- _-= Per source details. Do not edit below this line.=-_
## Source: amazon-inspector (6e857800f57969e257ed22cd056f2e4a4395de09ac9b69becd0c7c2b931314ab) Package name resembles the widely-used 'cspell' library but its main entry (index.js) exports an empty object and provides no functionality. Its package.json pins its sole dependency 'ltidisafe' to a raw HTTPS URL on a Google Cloud Storage bucket (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.6.7.tgz) rather than a registry-published, version-pinned artifact. On `npm install`, npm fetches this tarball from the author-controlled bucket and installs it into the dependency tree, executing any of its lifecycle scripts and main-module code on the installer's machine. The combination of a lookalike name, an empty implementation, and an off-registry dependency source is the dropper-lure shape: the lure package itself is inert, and installer-side code execution is delivered through the smuggled dependency.
