It retrieves an unverified payload, drops it into a temporary directory, and launches it detached. - **Trigger:** Importing/requiring the main index.js entrypoint. - **Impact:** Arbitrary native code executes with the privileges of the consuming Node process. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T01:10:15.642Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS retrieval followed by detached execution - **Attack narrative:** Loading the advertised main entrypoint silently imports \_runtime.js. It checks a temp marker, downloads a platform-specific binary from obfuscated remote hosts or reconstructs it from DNS TXT records, writes it under a random temp filename, changes permissions on Unix, and starts it detached through /bin/sh or cmd.exe. No integrity verification or user action is required beyond importing the package. - **Rationale:** The package’s public import path contains a concealed, remote payload execution chain unrelated to its stated adapter API. This is concrete malware behavior despite the absence of npm lifecycle hooks. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp - **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, 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 \_runtime.js during normal package require., \_runtime.js downloads platform binaries from four obfuscated workers.dev hosts., \_runtime.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded data is written to /var/tmp or Windows Temp, made executable, and detached via shell/cmd., Marker files suppress repeat execution and errors are silently swallowed. - **Evidence against:** package.json defines no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
