This is a concrete install-time data-exfiltration callback. - **Trigger:** npm installation, via postinstall - **Impact:** Exposes host identity, username, working directory, runtime/platform details, CI state, and npm client metadata. - **Evidence paths:** package.json, dc.js, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-21T18:50:39.883Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall host-metadata collection and HTTPS webhook exfiltration - **Attack narrative:** On installation, npm runs dc.js. It gathers the hostname, current username, current working directory, platform, Node version, CI indicator, and npm user-agent, serializes them into a query string, and issues an HTTPS request to a webhook.site endpoint. Errors are suppressed, so the callback does not visibly disrupt the installation. The empty DNS listener does not execute a DNS callback. - **Rationale:** The package performs unconsented install-time collection and transmission of local installation metadata to an external endpoint. Its claimed research purpose does not remove the concrete exfiltration behavior. - **Files touched:** package.json, dc.js - **Network endpoints:** https://webhook.site/b00492c6-27ba-4ea0-a9cb-dd50b3770250/dc? ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes dc.js automatically during npm installation., dc.js collects hostname, local username, working directory, platform, Node version, CI flag, and npm user-agent., The collected installation metadata is sent to a third-party webhook over HTTPS., The callback is wrapped in a silent catch, avoiding install failure or visible errors. - **Evidence against:** No file writes, shell execution, dynamic code loading, or payload download were found., The optional DNS callback is inert because DNS\_LISTENER is an empty string. ## Public findings ### 1.
