It sends the encoded result to a third-party endpoint. - **Trigger:** npm installation, via the preinstall lifecycle hook - **Impact:** Exposure of system account records, host configuration, user identity, and readable shadow credentials. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T00:51:21.776Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** shell-based local file and identity exfiltration over curl POST - **Attack narrative:** During npm installation, the preinstall hook runs index.js. It executes curl through a shell, reads local account and host files plus identity information, base64-encodes the collected output, and transmits it in an HTTP request header to an external Beeceptor endpoint. - **Rationale:** This is concrete, unconsented install-time collection and external exfiltration of sensitive host data. The package contains no legitimate implementation that would justify this behavior. - **Files touched:** package.json, index.js, /etc/passwd, /etc/hosts, /etc/shadow - **Network endpoints:** https://youjoex.free.beeceptor.com/$(whoami)/$(hostname)/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** preinstall runs index.js during npm installation., index.js shells out through child\_process.exec., Install-time curl POST exfiltrates passwd, hosts, identity, and readable shadow data to an external host. - **Evidence against:** Only package.json and index.js are present; no legitimate package functionality is implemented. ## Public findings ### 1.
