It retrieves an unverified executable payload from remote worker or DNS hosts, drops it to a temporary directory, and starts it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T09:02:20.852Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, permission change, and detached execution - **Attack narrative:** A normal import of index.js silently requires \_runtime.js. That module selects a platform-specific URL, fetches a binary from obfuscated worker hosts or reconstructs one from DNS TXT records, writes it into a temporary directory, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is unconsented remote code execution unrelated to the advertised roles library. - **Rationale:** The package contains concrete, reachable remote payload execution on import. The absence of an install hook does not mitigate this runtime compromise. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, 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 \_runtime.js on every package import., \_runtime.js downloads a platform payload, including via DNS TXT fallback., \_runtime.js writes the payload to a temp path, chmods it, and launches it detached via shell/cmd., Remote hosts are obfuscated by string concatenation and errors/output are suppressed., lib/telemetry.js contains a parallel download-to-temp-and-execute capability. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent control-surface mutation was found. ## Public findings ### 1.
