It retrieves a platform-specific payload, stores it in temporary storage, and starts it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled code executes as the importing user's account. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:16:17.455Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached shell execution. - **Attack narrative:** The normal entrypoint silently loads \_shim.js. On import, it contacts rotating workers.dev hosts for a platform-specific payload, falls back to DNS TXT records under wel1.ru, writes any sufficiently large response to a temporary executable file, and launches it detached through cmd.exe or /bin/sh. The behavior is unrelated to the advertised adapter and provides remote code execution. - **Rationale:** Source inspection confirms an import-time staged-payload downloader and executor, not merely telemetry. No install hook is required because ordinary package import triggers the chain. - **Files touched:** index.js, \_shim.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe, lib/telemetry.js - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.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 immediately requires ./\_shim on package import., \_shim.js fetches platform binaries from worker hosts and DNS TXT fallback., \_shim.js writes downloaded content to /var/tmp or Windows temp, chmods it, then detached-spawns it., Remote payload execution is silent and only suppressed by opt-out environment variables., lib/telemetry.js contains a parallel configurable downloader/executor, though it is not exported by index.js. - **Evidence against:** package.json has no lifecycle scripts., The documented adapter class in index.js is otherwise minimal. ## Public findings ### 1.
