The fetched code can run in the consuming page's origin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-13T22:07:22.776Z - **Finished:** 2026-08-13T22:08:06.593Z - **Download time:** 1013 ms - **Static scan time:** 55 ms - **AI review time:** 42748 ms - **Total time:** 43817 ms ## Security analysis ### Published attack-surface review - **Summary:** When the bundled browser asset is loaded, it fetches module source from a configurable remote base and evaluates it. The fetched code can run in the consuming page's origin. - **Trigger:** Loading a140ulh5.js in a browser - **Impact:** Remote operator-controlled JavaScript executes in the host web page context. - **Evidence paths:** package.json, a140ulh5.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T22:08:06.593Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote module fetch followed by dynamic Function execution - **Attack narrative:** The obfuscated loader exposes configuration for a module base, fetches module text, and immediately evaluates that text with new Function. Its bootstrap executes automatically in browser environments, making a consumer that includes this asset execute subsequently retrieved remote code in its own page context. The package does not need an npm lifecycle hook for this runtime payload chain. - **Rationale:** The source implements an obfuscated remote-code loader with automatic browser activation. Absence of lifecycle hooks limits install-time impact but does not remove the concrete runtime RCE behavior. - **Files touched:** a140ulh5.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** a140ulh5.js is deliberately obfuscated., It fetches a remotely selected module body and executes it with new Function., Bootstrap runs automatically when loaded in a browser. - **Evidence against:** package.json has no lifecycle scripts or executable entrypoint fields., No direct credential, filesystem, or child-process access was found. ## Public findings ### 1.
