First, `openDemo()` platform-branches via `execSync` to open https://github.com/X3r0Day/BunnyHijack in the installer's default browser and to spawn the OS calculator (`calc` on Windows, `open -a Calculator` on macOS, `gnome-calculator`/`kcalc` on Linux) — the canonical `calc.exe` proof of unauthenticated code execution on the installer's host. Second, `cleanup()` walks every ancestor directory of `INIT_CWD`, `process.cwd()`, and the user's home directory, calling `fs.rmSync(..., {recursive:true, force:true})` against paths inside each ancestor's `node_modules`, `node_modules/.pnpm`, `node_modules/.bin/node*` shims, `~/.npm/_npx`, `~/.bun/install/cache`, and tmpdir entries; `cleanupPackageJson()` then reads each ancestor `package.json` and rewrites it via `fs.writeFileSync` after deleting matching entries from `dependencies`, `devDependencies`, `optionalDependencies`, and `peerDependencies`. The destructive recursive-force-rm operates well outside the package's own directory and reaches the user's home tree, and the spawned-process primitive can be retargeted to any binary in a future release.\n\n## Source: ghsa-malware (42ab043183eddea4feeeba6b04397cdda6189b7d4c4bfdb11197a88646a1deca)\nAny computer that has this package installed or running should be considered fully compromised.
