It harvests host and consuming-project identity data, then transmits it through DNS plus HTTP(S). - **Trigger:** npm preinstall; importing index.js also runs its top-level collection logic. - **Impact:** Discloses identifying workstation, network, and consuming-project metadata to an external callback. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T22:38:24.899Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host/project reconnaissance and multi-channel exfiltration - **Attack narrative:** At npm preinstall, index.js reads metadata from the consuming project and gathers user, host, local-network, public-IP, resolver, subnet, and installation-path data. It hex-encodes the JSON into DNS queries to an external callback and sends duplicate HTTP and HTTPS POST requests to the same host. The source deliberately supports multiple egress channels, so the data can leave even where some outbound traffic is filtered. - **Rationale:** This is concrete, unconsented install-time reconnaissance and exfiltration from the consuming environment. Research-oriented labels do not remove the external data-transfer attack surface. - **Files touched:** index.js, package.json, $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 executes index.js during npm installation., Reads the consuming project's package.json via INIT\_CWD/process.cwd., Collects username, home path, hostname, local/public IPs, DNS subnet, and project metadata., Encodes the collected JSON into DNS queries to an external callback., Also POSTs the same data over HTTP and HTTPS to the callback. - **Evidence against:** No child-process execution, payload download, or persistence is present., Source does not read environment-variable values, credentials, or arbitrary file contents. ## Public findings ### 1.
