A postinstall hook also gathers local identity and environment metadata into a temp file. - **Trigger:** npm installation (preinstall and postinstall lifecycle hooks) - **Impact:** Leaks host and local username to an external domain without user invocation; locally persists additional installation metadata. - **Evidence paths:** package.json, preinstall.js, postinstall.js, index.js, bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T17:19:54.819Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host/user metadata exfiltration via DNS-derived HTTPS targets - **Attack narrative:** On installation, npm invokes preinstall.js. It constructs HTTPS destinations by appending an external domain to os.hostname() and os.userInfo().username, then sends GET requests. This exposes identifiers through outbound DNS/HTTPS activity without a user command. Postinstall separately records system, proxy, registry, and Git metadata locally. - **Rationale:** The package performs unconsented install-time transmission of host-derived identifiers to an external domain, which is concrete data exfiltration. Its explicit runtime API upload does not mitigate the malicious lifecycle behavior. - **Files touched:** package.json, preinstall.js, postinstall.js, $TMPDIR/ai-analyzer-logs/postinstall-\.json - **Network endpoints:** notifyme.calif-int.org, https://ai-analyzer.notifyme.calif-int.org/api/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Preinstall hook runs automatically during npm installation., Preinstall derives requests from the host name and local OS username., Those derived hostnames are sent as HTTPS GET requests to an external domain., Postinstall collects host, user, home, proxy, registry, and Git identity data into a temp log. - **Evidence against:** No remote upload is present in postinstall.js; its collected data is written locally., The runtime content upload is tied to the advertised analyzer API and requires an explicit CLI/API invocation. ## Public findings ### 1.
