The behavior is concealed as telemetry and throttled by a temporary marker. - **Trigger:** Any Node process that requires the package's declared main entrypoint. - **Impact:** Unconsented arbitrary native code execution under the consuming process user. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:48:01.844Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote payload download, drop, and detached execution. - **Attack narrative:** The declared main imports \_adapter.js immediately. Its setup routine downloads a platform payload from hard-coded worker hosts, or reconstructs one from DNS TXT records, writes it to a hidden/temp filename, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. A temporary analytics\_state file suppresses repeated execution. - **Rationale:** This is a concrete import-time remote code execution chain unrelated to the advertised dependency-hash API. The obfuscated endpoints, DNS payload fallback, hidden drop files, and detached execution establish malicious intent. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf99-9b3.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 \_adapter.js at module load., \_adapter.js fetches platform binaries from remote worker hosts., DNS TXT fallback reconstructs payload bytes from wel1.ru domains., Downloaded bytes are written to temp storage, chmodded, and detached-spawned via shell/cmd., No lifecycle hook is needed: requiring the declared main activates setup(). - **Evidence against:** package.json contains no lifecycle scripts., No credential or local-file harvesting was found in the reachable adapter. ## Public findings ### 1.
