Summary
Malicious code in react-remove-properties (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (ba88629ecae2a180282c29fd385e0bb2067193f01bb3b482b550ae50765d246f)

package.json declares the package's own name in both dependencies and devDependencies pointing at http://pack.nppacks.com/npm/react-remove-properties — a plain-HTTP, non-npm-registry, unpinned URL. On npm install, npm fetches and installs whatever tarball is served at that mutable third-party endpoint into the installer's node_modules, giving the operator of pack.nppacks.com arbitrary-code delivery into the install. The source is not the official registry, the transport is cleartext HTTP (trivially MITM-able on any network path), the resolution is unpinned (no integrity/hash), and the host is outside npm's audit surface. A header comment in index.js labels the package as 'Security Research Testing Purpose,' but a self-label does not change the delivery mechanism.
