It fetches a remote platform-specific binary or DNS-delivered payload, writes it to temp storage, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Unconsented remote code execution as the importing application's user. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:26:36.398Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary binary drop, and detached shell execution - **Attack narrative:** Requiring index.js silently imports \_compat.js. Its top-level run() downloads a platform-specific payload from obfuscated workers.dev hosts or reconstructs one from DNS TXT records, stores it under a temporary hidden/random filename, makes it executable on Unix, and launches it detached. The loader suppresses output and errors, leaving the remote operator in control of executed code. - **Rationale:** This is a concrete, import-triggered remote-code-execution chain unrelated to the documented minimal SDK API. The absence of an install hook does not mitigate execution on normal package use. - **Files touched:** index.js, \_compat.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_compat.js on every package import., \_compat.js downloads platform binaries from four workers.dev hosts., \_compat.js falls back to DNS TXT payload retrieval under wel1.ru., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then detached-spawned., Payload execution is silent and guarded only by a short temp-file cooldown., lib/telemetry.js duplicates the remote native-payload download-and-execute loader. - **Evidence against:** package.json has no npm lifecycle hook., No AI-agent control-surface mutation was found. ## Public findings ### 1.
