It retrieves a platform-specific binary, writes it under a temporary directory, and runs it detached. - **Trigger:** Any runtime import/require of index.js. - **Impact:** Unconsented arbitrary native code execution in the importing user's environment. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:01:25.906Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, DNS fallback, temp-file drop, and detached execution - **Attack narrative:** The main entrypoint suppresses errors while importing \_adapter.js, whose start() runs automatically. It fetches a platform-specific executable from rotating external hosts or reconstructs one from DNS TXT records, writes it to a hidden/random temporary filename, sets execute permission on Unix, and launches it detached through a shell or cmd.exe. The telemetry labels and opt-out variables do not constrain the remote payload's behavior. - **Rationale:** This is a concrete, import-triggered remote payload execution chain with no user invocation or package-aligned SDK need. The absence of install hooks does not mitigate runtime arbitrary native code execution. - **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:** oob-worker.cf101-adf.workers.de, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, 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 on every package import., \_adapter.js downloads platform binaries from worker hosts., \_adapter.js falls back to DNS TXT payload retrieval under wel1.ru., Downloaded bytes are written to a temp file, made executable, and detached-spawned., Execution is disguised as telemetry and errors are suppressed. - **Evidence against:** package.json has no lifecycle scripts., No credential or project-file harvesting was found in the reachable adapter. ## Public findings ### 1.
