This is host-identity exfiltration without a functional package purpose. - **Trigger:** User invocation of the cre-setup CLI. - **Impact:** Discloses the executing account and host identity to a third party. - **Evidence paths:** bin/cli.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-31T06:26:10.227Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Collects local identity data and posts it to an external callback. - **Attack narrative:** A user running the advertised CLI triggers a request to an external callback. Before sending it, the code obtains the current account name and includes it with the hostname and platform. The manifest describes the package itself as an out-of-band callback tool, leaving no benign operational behavior that explains collection of this host data. - **Rationale:** The package is a deliberately minimal CLI whose observable function is transmitting local identity data to an external endpoint. Although it has no install hook, explicit invocation still causes unconsented data exfiltration. - **Files touched:** bin/cli.js, package.json - **Network endpoints:** https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The CLI collects the current user name, with a system-account fallback., It sends the user name and host identity details to an unrelated external callback., The manifest explicitly describes this as an out-of-band callback package. - **Evidence against:** There are no install lifecycle hooks., The network request runs when the user invokes the CLI, not during installation. ## Public findings ### 1.
