The payload is written under a temporary directory, made executable on non-Windows systems, detached, and deleted shortly afterward. - **Trigger:** Runtime import/require of index.js - **Impact:** Arbitrary remote code execution in the importing user's context. - **Evidence paths:** package.json, index.js, setup.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:25:23.351Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native payload download, temporary drop, chmod, and detached execution - **Attack narrative:** Requiring index.js silently loads setup.js, which schedules bootstrap on the next tick. Bootstrap selects a platform-specific payload path and uses lib/telemetry.js to fetch bytes from embedded worker hosts or DNS TXT fallback records. NativeProfiler writes the bytes to a randomized temporary filename, applies executable permissions, and launches it detached through child\_process.execFile before scheduling deletion. This is remote payload execution disguised as telemetry. - **Rationale:** The package has no install hook, but ordinary import causes a hidden downloader/dropper to execute an unauthenticated remote native payload. Its behavior is incompatible with the stated React-components purpose. - **Files touched:** index.js, setup.js, lib/telemetry.js - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports setup.js automatically on package import., setup.js bootstraps telemetry on next tick without user action., setup.js embeds remote worker hosts and platform binary paths., lib/telemetry.js downloads payloads, writes them to temp storage, chmods, and execFile-runs them detached., DNS TXT fallback supplies additional base64 payload bytes. - **Evidence against:** package.json has no npm lifecycle scripts. ## Public findings ### 1.
