Malicious code in transform-es2015-unicode-regex (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (e85a13111400ea4b22bb2ae0d51ad784a89bc548d56b496a855bf7e6d6595804) package.json declares the package's own name as a dependency (and devDependency) with the specifier http://pack.nppacks.com/npm/transform-es2015-unicode-regex, a plain-HTTP, non-registry, third-party host unrelated to the legitimate babel-plugin-transform-es2015-unicode-regex it name-resembles. When a consumer runs `npm install`, npm fetches whatever tarball that URL currently returns and installs it, running any lifecycle scripts and making the fetched code require-able — arbitrary install-time code execution controlled by the operator of pack.nppacks.com, over an unauthenticated cleartext channel that is also trivially MITM-able. The package's index.js is not the referenced Babel plugin's code and carries a self-labeled 'Security Research Testing Purpose' comment; the name mimics babel-plugin-transform-es2015-unicode-regex, increasing the chance of accidental installation. ## Source: ghsa-malware (ea2ac6f4ef32dc1304670cd1c1d190f775857b229f650467ccbb4a6322950d1f) 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
