It exfiltrates the data through DNS plus HTTP and HTTPS callbacks. - **Trigger:** npm preinstall - **Impact:** Unconsented disclosure of developer/CI and project-identifying metadata. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T10:57:47.587Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host reconnaissance and multi-channel data exfiltration - **Attack narrative:** On npm installation, the preinstall hook runs index.js. It reads the consuming project's manifest and gathers user, home, hostname, local/public/resolver network data, working directory, and project metadata. The package hex-encodes the JSON into DNS queries and also POSTs it over HTTP and HTTPS to a fixed external callback, allowing reporting even through restricted egress paths. - **Rationale:** This is concrete, unconsented preinstall-time host and project metadata exfiltration to a fixed third-party callback. A stated research purpose does not remove the install-time disclosure. - **Files touched:** 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 executes index.js without user action., Reads consuming project metadata from INIT\_CWD/package.json., Collects username, home directory, hostname, IPs, and working directory., Encodes the collected JSON into DNS queries and POSTs it to a fixed callback. - **Evidence against:** No credential, environment-variable, or arbitrary file-content harvesting found., No shell execution, payload download, persistence, or destructive action found. ## Public findings ### 1.
