It fetches a platform payload, writes it to temporary storage, and starts it detached. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary native code execution under the importing user's permissions. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:29:17.090Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, drop, chmod, and detached execution - **Attack narrative:** The package’s declared main file catches errors while importing \_loader.js, so normal runtime import silently activates it. The loader retrieves a large platform-specific binary over HTTPS or reconstructs one from DNS TXT records, drops it under a benign-looking temporary filename, makes it executable on Unix, and launches it detached. This is an unconsented remote-code execution chain, not functionality needed by the exposed UI API. - **Rationale:** Direct source inspection confirms an import-time downloader/dropper/executor with concealed endpoints and no payload validation. The absence of an npm lifecycle hook does not mitigate execution on normal package import. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, 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 \_loader.js on every package import., \_loader.js downloads platform binaries from four worker hosts., \_loader.js falls back to DNS TXT payload retrieval from dl.wel1.ru hosts., \_loader.js writes a hidden/random executable in temp storage and chmods it., \_loader.js launches the downloaded file detached via cmd.exe or /bin/sh., Network, execution, and failures are deliberately silent. - **Evidence against:** package.json has no lifecycle scripts., index.js exposes a small UI-looking API, but its import side effect is unrelated. ## Public findings ### 1.
