It fetches a platform-specific executable, writes it under a temporary directory, then runs it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T18:06:03.403Z - **Finished:** 2026-08-05T18:06:46.738Z - **Download time:** 253 ms - **Static scan time:** 31 ms - **AI review time:** 43049 ms - **Total time:** 43335 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately starts a remote payload loader. It fetches a platform-specific executable, writes it under a temporary directory, then runs it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Unconsented arbitrary code execution as the importing user's account. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:06:46.738Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** obfuscated remote binary download, drop, chmod, and detached execution - **Attack narrative:** Loading the advertised module invokes \_runtime.js under a swallowed error handler. That code selects a platform-specific path, retrieves at least 1 KB from rotating Cloudflare worker hosts or DNS TXT chunks, writes it to a temporary executable-like path, grants execute permission on Unix, and launches it detached. Its separate telemetry file contains the same downloader/runner design. - **Rationale:** This is a concrete import-time remote payload execution chain, not ordinary telemetry. The obfuscated endpoint construction and detached execution establish malicious 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:** oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.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 require., \_runtime.js downloads platform payloads from four worker hosts or DNS TXT records., Downloaded bytes are written to a temp file, chmodded on Unix, and detached-spawned via shell/cmd., Remote endpoints and DNS domains are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., No credential-harvesting or project-file collection was found in the entrypoint chain. ## Public findings ### 1.
