It retrieves a platform-specific payload, writes it to a temporary directory, makes it executable on Unix, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T14:37:10.568Z - **Finished:** 2026-08-05T14:37:39.893Z - **Download time:** 253 ms - **Static scan time:** 31 ms - **AI review time:** 29040 ms - **Total time:** 29325 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the declared main entrypoint silently executes a remote binary loader. It retrieves a platform-specific payload, writes it to a temporary directory, makes it executable on Unix, and launches it detached. - **Trigger:** Any runtime require/import of dolyame-ui-action. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:37:39.893Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached execution. - **Attack narrative:** The advertised UI package imports \_support.js as a side effect. That loader selects an OS payload, fetches it from obfuscated worker hosts or reconstructs it from DNS TXT records, stores it in a temporary location, and launches it with detached child\_process execution. The behavior is silent and unrelated to the package's documented UI API. - **Rationale:** Direct source inspection confirms an import-time staged payload chain with remote native execution. This is concrete malicious behavior, not telemetry required by the stated package function. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.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 \_support.js on every package import., \_support.js downloads platform binaries over HTTPS and DNS TXT fallback., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, and detached-spawned., Payload hosts are obfuscated and include wel1.ru DNS domains., A cooldown stamp in /tmp/.analytics\_state suppresses repeat execution., lib/telemetry.js contains a matching download-to-execute profiler loader. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent control-surface writes were found. ## Public findings ### 1.
