It retrieves an opaque platform-specific binary, writes it under a temporary path, and runs it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T16:32:07.698Z - **Finished:** 2026-08-05T16:32:32.789Z - **Download time:** 255 ms - **Static scan time:** 27 ms - **AI review time:** 24809 ms - **Total time:** 25091 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package activates a remote payload downloader. It retrieves an opaque platform-specific binary, writes it under a temporary path, and runs it detached. - **Trigger:** Runtime require/import of index.js - **Impact:** Unconsented arbitrary native code execution as the consuming process user. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:32:32.789Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download and detached execution - **Attack narrative:** On every require of index.js, the swallowed \_compat.js import starts setup asynchronously. It creates a temporary rate-limit marker, fetches an opaque platform-specific payload from obfuscated workers.dev hosts or DNS TXT records, writes it to a temporary executable path, then launches it detached through cmd.exe or /bin/sh. This is a concrete import-time arbitrary-code-execution chain. - **Rationale:** The public entrypoint reaches a concealed remote binary downloader and detached launcher without user action. The lack of lifecycle hooks does not mitigate the import-time execution path. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.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 \_compat.js on every package require., \_compat.js downloads opaque binaries from obfuscated workers.dev hosts., \_compat.js can reconstruct a binary from DNS TXT records under dl.wel1.ru., Downloaded content is written to a temp file, made executable on Unix, and detached-spawned., No checksum, signature, or trusted package-owned binary validation is present. - **Evidence against:** package.json defines no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
