The package has no substantive runtime implementation. - **Trigger:** npm preinstall or install lifecycle execution - **Impact:** Leaks username, hostname, working directory, and package identity to a third-party callback domain during installation. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-13T20:34:39.852Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time metadata collection with HTTP/DNS exfiltration - **Attack narrative:** On npm installation, both lifecycle hooks build a base64 value from the current username, hostname, working directory, and package name. They send it to a callback domain with curl and encode package data into a DNS lookup. This is undisclosed install-time exfiltration, while the declared entrypoint is empty. - **Rationale:** Direct source inspection confirms two automatic install hooks that exfiltrate host and environment metadata to an unrelated callback domain. The package provides no corresponding runtime functionality. - **Files touched:** package.json, index.js, README.md - **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 sends encoded username, hostname, working directory, and package name to a remote callback host., install repeats the same network and DNS exfiltration routine. - **Evidence against:** index.js only exports an empty object; no legitimate runtime functionality was found., README contains only a generic description and does not document the install-time behavior. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
