It stores a platform payload in a temporary directory and launches it detached. - **Trigger:** Any runtime require/import of the package entrypoint - **Impact:** Arbitrary attacker-controlled native code executes under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:04:09.875Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary drop, and detached execution - **Attack narrative:** Requiring index.js silently requires \_shim.js, which immediately calls run(). It selects a platform-specific endpoint, fetches a binary from obfuscated Workers hosts or reconstructs it from DNS TXT records, writes it under /var/tmp or the Windows temp directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The payload is not verified against an expected hash. - **Rationale:** This is concrete import-time remote-code execution unrelated to the declared component package. The absence of install hooks does not mitigate execution on ordinary package use. - **Files touched:** index.js, \_shim.js - **Network endpoints:** oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, 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 \_shim.js on every package require., \_shim.js downloads platform binaries from worker hosts or DNS TXT., \_shim.js writes the payload to a temp path, chmods it, then detached-spawns it., The remote payload has no enforced integrity validation. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent configuration mutation was found. ## Public findings ### 1.
