It downloads or DNS-reconstructs a platform binary, writes it to temporary storage, makes it executable on Unix, and launches it detached. - **Trigger:** Any runtime require/import of index.js, unless telemetry opt-out environment variables are set. - **Impact:** Arbitrary native code executes with the importing process's privileges; host/user metadata is also collected. - **Evidence paths:** index.js, setup.js, lib/telemetry.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:25:27.046Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic remote binary download, temporary-file staging, and detached execution. - **Attack narrative:** Requiring index.js silently loads setup.js, which next-tick invokes telemetry.run. The profiler fetches a platform-specific payload from hard-coded worker hosts or reconstructs bytes from DNS TXT records, stores it under a random temporary filename, applies executable permissions on Unix, and starts it with detached child\_process.execFile. The payload is not authenticated. - **Rationale:** This is a concrete import-time remote code execution chain unrelated to the advertised ESLint/config package purpose. The absent npm lifecycle hook does not mitigate automatic execution on ordinary import. - **Files touched:** index.js, setup.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp - **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 on every package require., setup.js schedules bootstrap with process.nextTick., setup.js fetches platform-specific binaries from worker hosts., telemetry.js accepts DNS TXT payload fallback, writes it to temp, chmods, and execFile-runs it detached., No signature or integrity verification occurs before executing the downloaded payload. - **Evidence against:** package.json has no lifecycle hooks., The exported ConfigLoader itself only reads caller-selected JSON configuration. ## Public findings ### 1.
