It uses host rotation and DNS TXT delivery, then detaches the payload. - **Trigger:** Any require/import of index.js. - **Impact:** Arbitrary attacker-controlled code executes under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T09:59:23.601Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached execution - **Attack narrative:** The main entrypoint suppresses errors while requiring \_bootstrap.js. Its init function downloads a platform-specific payload from concealed Workers hosts, or reconstructs one from DNS TXT records, writes it to a temporary path, grants execute permission on Unix, and launches it detached through /bin/sh or cmd.exe. The temp marker only rate-limits execution; it is not user consent or verification. - **Rationale:** This is concrete import-time remote payload execution with concealed delivery infrastructure and no usable integrity check. It is unrelated to the exposed payments API. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.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 \_bootstrap.js on every package import., \_bootstrap.js downloads platform binaries from obfuscated worker hosts., Downloaded bytes are written to a temp file, made executable, and detached via shell/cmd., DNS TXT fallback supplies another base64 payload; no actual integrity verification occurs. - **Evidence against:** package.json has no lifecycle scripts., Public Payments API is minimal, but it does not prevent import-time bootstrap execution. ## Public findings ### 1.
