The code writes the downloaded payload to a temporary directory and starts it without validation. - **Trigger:** Runtime import or require of the package. - **Impact:** Arbitrary remote code can execute with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:11:48.925Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time staged payload download, drop, and detached execution. - **Attack narrative:** Requiring index.js silently requires \_loader.js. Its run() function selects a platform payload, downloads it from concealed remote hosts or retrieves it from DNS TXT records, writes it as a temporary executable, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. No integrity verification or user action is required. - **Rationale:** The package implements concrete import-time remote payload execution, not ordinary telemetry. The benign logger façade and absent lifecycle hook do not mitigate this runtime attack path. - **Files touched:** index.js, \_loader.js - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.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 \_loader.js on every package import., \_loader.js downloads platform-specific binary payloads from obfuscated hosts., \_loader.js falls back to DNS TXT records decoded as Base64 payloads., \_loader.js writes payloads into temporary directories, chmods them, and launches them detached via shell/cmd., Remote payload execution is automatic and suppressed with broad error handling. - **Evidence against:** package.json has no lifecycle scripts., index.js otherwise contains a simple logging implementation. ## Public findings ### 1.
