    "summary": "animatecss-tailwind-bridge 2.0.6 was published to npm on 2026-09-13 by the account bennetwild. The package is part of a fake job interview campaign that targets developers, using the same method as the \"Contagious Interview\" campaign. A fake company sends a take-home coding assessment repository. The repository commits a web/.npmrc containing a plaintext npm auth token, and its tailwind.config.js loads this package as a Tailwind CSS plugin. The package presents itself as an Animate.css integration (\"A configurable, namespaced Animate.css integration for Tailwind CSS\", main plugin.js) but declares a runtime dependency on a private scoped npm package (@jasperquinn/postcss-motion-helpers) that is not publicly readable, so npm audit and public scanners cannot see it; it only resolves with the token committed in the lure repository. The package has no install scripts, so --ignore-scripts does not help: the code runs when Tailwind loads the config, i.e. on `npm run dev` / `next dev`. Public analysis of the earlier package in this chain (animatecss-tailwind-adapter, by Yunus Aydın) reports that the private package contacts an operator-controlled server and runs the code it receives with full Node.js privileges. A public write-up by a targeted developer describes this package as the dependency in a lure repository for a Solana copy-trading dashboard from a fake company \"BlockRoute Labs\" (blockroutelabs.com), recruited through Djinni.co. It depends on the same private package as tailw",
