## From the sources

identity-two-factor@999.0.0 is a dependency-confusion package aimed at Coinbase (its README and postinstall.js say so, and the beacon path is `cbhq-canary`) with no functional code. Its postinstall script runs `node postinstall.js` on npm install, which writes a marker file to the temp directory and POSTs the hostname, username, working-directory name, CI flag and Node version to `https://webhook.site/e0981a8e-081e-49a0-8b4a-235109e13045/cbhq-canary`. It was published by the npm account hologrammmm0x, which has no other packages.
