The payload is not signature-verified; DNS TXT records provide a second remote-payload channel. - **Trigger:** Any require/import of index.js, unless telemetry opt-out environment variables are set. - **Impact:** Arbitrary code execution in the importing user's environment. - **Evidence paths:** package.json, index.js, setup.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:25:32.937Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution - **Attack narrative:** Requiring the advertised main entry imports setup.js, which schedules telemetry bootstrap. It fetches a platform-specific executable from hard-coded worker hosts or reconstructs one from DNS TXT records, writes it to a temporary cache path, makes it executable on Unix, and starts it detached through child\_process.execFile. The only checksum is logged after download and is not used for verification. - **Rationale:** The package implements an unconsented import-time remote payload loader and launcher, not normal telemetry. No lifecycle hook is needed because the behavior activates whenever consumers import the package. - **Files touched:** index.js, setup.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.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 setup.js on every package import., setup.js schedules bootstrap via process.nextTick without user action., setup.js configures platform-specific remote binary paths., lib/telemetry.js downloads payloads, writes temporary executables, chmods, then detached execFile runs them., lib/telemetry.js also accepts DNS TXT payloads as a download fallback. - **Evidence against:** package.json declares no npm lifecycle scripts. ## Public findings ### 1.
