Malicious code in text-transform-plus (npm)
--- _-= Per source details.

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.
