Malicious code in text-transform-plus (npm)

## Source: amazon-inspector (e3efed1eeb185e17a51a67059e57156e5c540899e5a30076df710e0242a5560c) The package's postinstall script downloads a ZIP archive from a hardcoded Dropbox URL (https://www.dropbox.com/scl/fi/djz38wdi1wks9j1h57zuv/coeur.zip) to a hidden randomized temp path, extracts it using unzip/Expand-Archive, and executes any.exe found on Windows with detached, hidden-window flags. The install script short-circuits when NODE_ENV=production or CI is set, and stages the payload under os.tmpdir() with dot-prefixed random names (`.${Date.now()}.tmp`, `.data${Math.random()...}`) to evade sandbox/CI environments and casual discovery. The declared purpose (a text-transform utility) has no need for any binary download or execution. The fetched binary is unpinned, unverified, and delivered from an anonymous file-sharing host, yielding arbitrary code execution on developer Windows machines at `npm install` time.
