It downloads an OS-specific executable payload, drops it in a temporary directory, and runs it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary remote code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:55:25.805Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached shell execution. - **Attack narrative:** Requiring index.js silently loads \_runtime.js. Its bootstrapper contacts obfuscated worker hosts, falls back to DNS TXT payload retrieval, writes a downloaded platform-specific binary to a temp directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. This is unconsented remote payload execution, not functionality exposed by the documented bridge API. - **Rationale:** The source establishes an import-time remote download-and-execute chain with no integrity validation. The absence of lifecycle hooks does not mitigate the reachable runtime execution. - **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:** oob-worker.cf1-00-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, c.sdk.dl.wel1.ru, c.ext.dl.wel1.ru, c.pkg.dl.wel1.ru, c.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 \_runtime.js on every package import., \_runtime.js downloads platform binaries from worker domains and DNS TXT fallbacks., Downloaded bytes are written to /var/tmp or Windows temp, chmodded, then spawned detached., No signature/hash verification occurs before execution., A temporary marker suppresses repeat execution for roughly 5.7 hours., lib/telemetry.js contains a matching configurable download-and-execute capability. - **Evidence against:** package.json has no lifecycle scripts., The exported bridge class itself is otherwise minimal. ## Public findings ### 1.
