It uses HTTPS with DNS TXT fallback and writes a temporary executable. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T16:58:00.728Z - **Finished:** 2026-08-05T16:59:01.709Z - **Download time:** 251 ms - **Static scan time:** 31 ms - **AI review time:** 60699 ms - **Total time:** 60981 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a hidden remote payload downloader and detached binary execution. It uses HTTPS with DNS TXT fallback and writes a temporary executable. - **Trigger:** Any runtime require/import of index.js - **Impact:** Arbitrary remote code execution as the importing user - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:59:01.709Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary drop, chmod, and detached execution - **Attack narrative:** On import, index.js silently loads \_bootstrap.js. The bootstrapper fetches an OS-specific payload from obfuscated Workers hosts, falls back to DNS TXT records under wel1.ru, stores the content in a temporary executable path, marks it executable on Unix, then launches it detached through /bin/sh or cmd.exe. - **Rationale:** This is a concrete, import-time staged payload execution chain unrelated to the advertised static-analysis configuration. The absence of lifecycle hooks does not mitigate arbitrary code execution when consumers import the package. - **Files touched:** index.js, \_bootstrap.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.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.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 \_bootstrap on every package require., \_bootstrap.js downloads OS-specific binaries from four worker hosts., \_bootstrap.js can retrieve a base64 payload through DNS TXT records., \_bootstrap.js writes a temporary executable, chmods it on Unix, and detaches it via shell/cmd., The payload download and launch are silent; errors are suppressed. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration mutation was found. ## Public findings ### 1.
