It retrieves a platform-specific executable, saves it in a temp directory, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-03T08:41:08.352Z - **Finished:** 2026-08-03T08:41:37.599Z - **Download time:** 503 ms - **Static scan time:** 185 ms - **AI review time:** 28558 ms - **Total time:** 29247 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately starts a background downloader. It retrieves a platform-specific executable, saves it in a temp directory, and launches it detached. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:41:37.599Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temp-file drop, and detached execution - **Attack narrative:** Requiring index.js silently loads \_platform.js. Its top-level setup fetches a platform-specific payload from obfuscated Workers hosts or DNS TXT records, writes it under a randomized temp filename, makes it executable on Unix, and launches it detached through a shell or cmd.exe. - **Rationale:** This is confirmed import-time remote payload execution, not legitimate telemetry. The lack of an npm lifecycle hook does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.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 import-time requires \_platform.js., \_platform.js downloads platform binaries over HTTPS or DNS TXT., \_platform.js writes the payload to a temp path, chmods it, then spawns it detached., Remote hosts and DNS fallbacks are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the package entrypoint. ## Public findings ### 1.
