The empty runtime entrypoint does not mitigate install-time exfiltration. - **Trigger:** npm package installation - **Impact:** Leaks installing user's username, hostname, current directory, and package name to a third-party callback service. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-13T20:34:49.344Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** lifecycle-based host metadata exfiltration via HTTPS and DNS - **Attack narrative:** On npm installation, both preinstall and install construct a base64 value from whoami, hostname, pwd, and the package name. The script places that value in an HTTPS callback path and also emits a DNS lookup to the same callback domain. This happens without an explicit user command and is unrelated to the package's empty runtime export. - **Rationale:** Source inspection confirms unconsented install-time collection and transmission of local environment metadata to a callback domain. This is concrete data exfiltration behavior. - **Files touched:** package.json - **Network endpoints:** https://$pkgsub.callback.m0chan.co.uk/$b64, $pkgdns.$pkgsub.callback.m0chan.co.uk ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Preinstall collects username, hostname, working directory, and package name., The hook exfiltrates encoded host data through HTTPS and DNS., Install repeats the same automatic collection and network callbacks. - **Evidence against:** index.js only exports an empty object; no runtime behavior found., No additional package files contain execution or network logic. ## Public findings ### 1.
