Its public checkBan API transmits a supplied phone number to an unrelated third-party endpoint. - **Trigger:** Importing lib/index.js; invoking socket.checkBan(number). - **Impact:** Consumer IP/usage metadata is disclosed on import; supplied WhatsApp phone numbers are disclosed to the third-party host. - **Evidence paths:** lib/index.js, lib/Socket/socket.js, package.json, engine-requirements.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T19:21:22.014Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time beacon and third-party phone-number transmission. - **Attack narrative:** At module import, the package contacts a maintainer-controlled remote URL solely to display update information. Separately, its exported checkBan helper places the caller's phone number in a request URL to xzc-corporation.biz.id, an endpoint unrelated to WhatsApp, with a suspicious nonstandard header. This is concrete disclosure of user-supplied personal data to an undisclosed third party. - **Rationale:** Source inspection confirms unsolicited import-time networking and a public helper that exfiltrates caller-supplied phone numbers to an unrelated host. The install hook itself is benign, but it does not mitigate the runtime disclosure. - **Files touched:** lib/index.js, lib/Socket/socket.js, package.json, engine-requirements.js - **Network endpoints:** https://raw.githubusercontent.com/alannzxd/xclient/refs/heads/main/information.json, https://xzc-corporation.biz.id/lrp?number= ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing the public entrypoint immediately fetches a maintainer-controlled GitHub URL., Public checkBan sends its caller-supplied phone number to unrelated xzc-corporation.biz.id with a nonstandard offensive header., checkBan is returned on the socket API, making that disclosure callable by package consumers. - **Evidence against:** The preinstall hook only rejects Node versions below 20; it does not modify files or network state., No source evidence of credential harvesting, remote code execution, or agent-control-surface mutation was found. ## Public findings ### 1.
