AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package implements undisclosed host-identity exfiltration to an unrelated endpoint on command execution. Although it has no install hook, this is concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-31T06:28:27.074Z - **Finished:** 2026-08-31T06:29:00.663Z - **Download time:** 502 ms - **Static scan time:** 12 ms - **AI review time:** 33074 ms - **Total time:** 33589 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Invoking the CLI collects local user and host identity information and transmits it to an external callback. No automatic install-time trigger exists. - **Trigger:** Running cre-setup, including through npx. - **Impact:** Discloses the local account name, host name, operating system platform, and package identity to a third party. - **Evidence paths:** bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T06:29:00.663Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Host identity collection followed by an outbound POST request. - **Attack narrative:** When the user runs the CLI, it runs whoami or reads the OS account name, obtains the host name and platform, then POSTs those values to an external callback. The package catches network errors so the collection can remain unobtrusive. - **Rationale:** The package implements undisclosed host-identity exfiltration to an unrelated endpoint on command execution. Although it has no install hook, this is concrete malicious behavior. - **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 block:** The command collects the current account name by running whoami, with an OS-account fallback., It sends the account name, host name, and platform to an unrelated external callback., The network request runs whenever the package CLI is invoked and suppresses failures. - **Evidence against:** There is no preinstall, install, or postinstall lifecycle hook., The observed behavior is limited to the user-invoked CLI; no persistence or file modification is present. ## Affected versions and remediation This report applies to cre-setup@1.0.0. - Avoid installing cre-setup@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
