It downloads a remote binary, drops it in a temp directory, and executes it detached. - **Trigger:** Runtime import/require of devplatform-po-loader - **Impact:** Arbitrary code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:32:31.850Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached execution - **Attack narrative:** Requiring the declared main entrypoint loads \_platform.js. That module fetches a platform-specific payload from obfuscated remote hosts, with DNS TXT records as a fallback, writes it to a temporary path, makes it executable on Unix, and starts it through a detached shell or cmd.exe process. Its marker only limits repeat execution; it does not require explicit user setup. - **Rationale:** The import-time loader establishes a concrete remote-payload execution chain. The unused telemetry module contains materially similar downloader/executor logic, reinforcing intent. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.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 \_platform.js on every package import., \_platform.js downloads platform binaries from hard-coded hosts., \_platform.js falls back to DNS TXT payload retrieval., \_platform.js writes the payload under /var/tmp or temp., \_platform.js chmods and detached-spawns the downloaded payload. - **Evidence against:** package.json has no lifecycle scripts. ## Public findings ### 1.
