This is unconsented host-information exfiltration. - **Trigger:** A user runs the fuels-core CLI, including through npx. - **Impact:** The external operator receives the local username, hostname, platform, and package identity. - **Evidence paths:** bin/cli.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-31T06:20:26.186Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Collect local identity data and POST it to a remote callback. - **Attack narrative:** The executable CLI runs whoami or reads the operating-system username, then posts that value along with hostname and platform to an external workers.dev endpoint. It suppresses network errors, making the collection silent to the caller. Although it has no install hook, execution of its advertised command causes the exfiltration. - **Rationale:** The package has no apparent functional purpose beyond sending local host identity data to an out-of-band endpoint. The explicit collection and transmission are concrete malicious behavior when the CLI is invoked. - **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 obtains the local account name by running whoami, with an operating-system fallback., When the CLI runs, it sends the account name, hostname, and platform details to an unrelated external callback., The package metadata explicitly describes an out-of-band callback that receives package and user identity data. - **Evidence against:** There is no npm install lifecycle hook, so the behavior does not run automatically during installation., The inspected source does not show file theft, persistence, or destructive actions. ## Public findings ### 1.
