Package name 'git-userhub' is a lookalike of a GitHub-related identity, with no legitimate publisher backing. The package.json declares a postinstall hook ("postinstall": "node install.js") that runs install.js on every npm install. install.js requires child_process and performs multiple https.get calls together with hostname/identity reads — the canonical install-time fetch-and-exec shape. There is no shipped native source tree, no publisher-matching CDN, and no version-pinned binary that would justify a postinstall network fetch. Combined with the lookalike package name (git-<project> typosquat shape used by recent supply-chain droppers), the structure matches a postinstall dropper that spawns child processes against fetched content on the installer's machine. Installing this package risks remote code execution and host/identity exfiltration on the installer's system or CI runner.
