It uses a temporary marker to limit repeat execution. - **Trigger:** Runtime import or require of beaver-ui-side-navigation - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_helpers.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:08:45.204Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download, temporary-file drop, and detached execution - **Attack narrative:** The main entrypoint catches and ignores errors while requiring \_helpers.js. That module immediately downloads a binary from rotating obfuscated hosts, falling back to DNS TXT payload reconstruction, writes it to a temporary location, marks it executable on Unix, and launches it detached through a shell or cmd.exe. This is an unconsented import-time remote-code-execution chain unrelated to the stated React-components purpose. - **Rationale:** Source directly confirms an import-triggered remote binary downloader and detached launcher; the lack of an npm lifecycle hook does not mitigate runtime import execution. - **Files touched:** index.js, \_helpers.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.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 \_helpers.js on every package import., \_helpers.js downloads platform binaries from obfuscated worker hosts or DNS TXT., \_helpers.js writes fetched bytes to /var/tmp or Temp, chmods them, then detached-spawns them., The download-and-execute path runs at import time via setup()., lib/telemetry.js contains a parallel remote-extension downloader and launcher. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or explicit data-exfiltration path was found. ## Public findings ### 1.
