It exfiltrates that data through DNS plus HTTP and HTTPS callbacks. - **Trigger:** Installing the dependency runs \`node index.js\` via \`preinstall\`. - **Impact:** An unconsented package install discloses machine identity, network identifiers, filesystem location, and consuming-project ownership metadata to a fixed external host. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-23T10:57:38.395Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time host and project metadata exfiltration via DNS and web callbacks. - **Attack narrative:** On installation, the preinstall hook runs automatically. It reads host and project metadata, resolves public and DNS-network identifiers, encodes the resulting JSON into DNS labels, and sends duplicate HTTP/HTTPS POST callbacks to a fixed external host. This is concrete unconsented installation-time data exfiltration, regardless of the stated research purpose. - **Rationale:** Direct source inspection confirms automatic preinstall execution and multiple outbound channels carrying collected host and consumer-project metadata. The declared dependency-confusion PoC intent does not remove the concrete privacy and exfiltration behavior. - **Files touched:** 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\` executes \`index.js\` automatically during dependency installation., The install script collects host, username, home directory, working directory, local/public IPs, DNS subnet, and consuming-project metadata., It hex-encodes the collected payload into DNS queries and also posts it over HTTP and HTTPS to a fixed callback host., The source reads the consuming project's \`package.json\` via \`INIT\_CWD\` to collect owner and repository metadata. - **Evidence against:** No credential, token, environment-variable, source-file, persistence, downloader, or command-execution logic was found., The package self-identifies as dependency-confusion research, but that does not make unconsented install-time telemetry benign. ## Public findings ### 1.
