Summary
Malicious code in @mohamed_nowisar/depconf-canary-test (npm)
Details

On npm install, the package's preinstall hook runs node beacon.js, which collects host identity (os.hostname(), os.userInfo().username, process.cwd(), platform, arch, Node version) and CI-detection environment variables (GITLABCI, GITHUBACTIONS, YANDEX_CI, and others) and POSTs them as JSON to the hardcoded endpoint https://webhook.site/3687e44a-4e97-43c4-84c9-e6c93d4b2fbc. The package name and self-description frame this as a dependency-confusion canary, but the beacon fires automatically on install without opt-in and sends installer-side data to an author-controlled webhook.site collector.
