It fetches a platform-specific binary, writes it to a temporary directory, and starts it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-06T01:15:01.056Z - **Finished:** 2026-08-06T01:15:26.334Z - **Download time:** 260 ms - **Static scan time:** 130 ms - **AI review time:** 24888 ms - **Total time:** 25278 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a hidden downloader. It fetches a platform-specific binary, writes it to a temporary directory, and starts it detached. - **Trigger:** Any runtime require/import of index.js, unless opt-out environment variables are set. - **Impact:** Unconsented arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T01:15:26.334Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution. - **Attack narrative:** The public entrypoint silently loads \_polyfill.js. Its start() function runs immediately, retrieves a binary from obfuscated worker hosts or DNS TXT records, saves it under a temporary cache-like filename, makes it executable on Unix, then launches it detached through a shell or cmd.exe. - **Rationale:** This is a concrete import-time remote payload execution chain unrelated to the advertised SDK. The absence of install hooks does not mitigate execution when an application imports the package. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, 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 \_polyfill.js on every package import., \_polyfill.js downloads OS-specific binary payloads., Downloaded bytes are written, chmodded, and spawned detached., Payload hosts are obfuscated and include DNS TXT fallback. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
