The package has no functional runtime implementation to justify this behavior. - **Trigger:** npm preinstall or install lifecycle execution - **Impact:** Leaks installing user's account name, hostname, working directory, and package identity to a third party during installation. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-13T20:34:38.220Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** encoded host metadata exfiltration via curl and DNS lookup - **Attack narrative:** On installation, preinstall and install build a base64 value from whoami, hostname, pwd, and the package name. They transmit it in an HTTPS path to a callback domain and also encode the package name into a DNS lookup. This is unconsented installation-time environment reconnaissance and external exfiltration. - **Rationale:** Direct manifest inspection confirms duplicated install-time collection and outbound callback requests. The empty entrypoint and generic README provide no package-aligned purpose for the behavior. - **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 collects username, hostname, working directory, and package name, then sends encoded data to a callback domain., install repeats the same HTTP and DNS exfiltration behavior during npm installation. - **Evidence against:** index.js only exports an empty object; no additional runtime behavior was found., README contains only a generic package description. ## 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.
