The package exfiltrates that data by DNS plus HTTP/HTTPS callbacks. - **Trigger:** npm preinstall runs node index.js - **Impact:** Unconsented disclosure of identifying workstation, network, and consuming-project metadata. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T00:06:02.557Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host and project reconnaissance with DNS/HTTP exfiltration - **Attack narrative:** On installation, the preinstall hook executes index.js. It reads the consuming project's package.json, gathers local and public network details plus hostname, username, home directory, and working directory, then serializes the data. The package sends that payload as hex-labelled DNS queries to its callback domain and as HTTP and HTTPS POST requests. Its stated research purpose does not establish consent for this automatic collection and external transmission. - **Rationale:** Direct source inspection confirms a reachable preinstall reconnaissance and data-exfiltration chain. This is concrete unconsented install-time behavior, independent of the package's stated research intent. - **Files touched:** package.json, index.js, \/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 during npm installation., Source reads consuming project's manifest and host/user/home/network identifiers., It queries public-IP services and a DNS resolver to expand collected network data., It hex-encodes the collected JSON into DNS requests and also POSTs it to an external callback. - **Evidence against:** No code writes files, downloads payloads, or invokes shell commands., README describes the behavior as security research, but source confirms unconsented install-time collection and transmission. ## Public findings ### 1.
