It fetches a platform payload over HTTPS or DNS TXT, writes it to a temporary path, and launches it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:37:40.810Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary executable drop, and detached execution. - **Attack narrative:** When an application imports index.js, it silently requires \_runtime.js. That module fetches a platform-specific binary from rotating workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. It stores the payload in a temporary file, marks it executable on Unix, and starts it through a detached shell or cmd.exe process while suppressing errors. This is concrete remote code execution unrelated to the advertised linter API. - **Rationale:** The package has no install hook, but its normal import path performs an unconsented remote-binary download and execution chain. The telemetry naming and opt-out variables do not make this package-aligned behavior. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** b-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 \_runtime.js on every package import., \_runtime.js downloads platform payloads from three workers.dev hosts., \_runtime.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to a temp executable, chmodded on Unix, then detached-spawned., The behavior is hidden behind a telemetry-style opt-out and errors are suppressed., lib/telemetry.js contains the same download-to-temp-and-execute mechanism. - **Evidence against:** package.json has no lifecycle scripts., index.js otherwise exposes only a small linter-named API. ## Public findings ### 1.
