This gives the remote host arbitrary JavaScript execution in the embedding page. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-08-13T20:42:14.752Z - **Finished:** 2026-08-13T20:42:58.747Z - **Download time:** 777 ms - **Static scan time:** 48 ms - **AI review time:** 43168 ms - **Total time:** 43995 ms ## Security analysis ### Published attack-surface review - **Summary:** The obfuscated browser loader fetches module source from a hidden configured base and executes it dynamically. This gives the remote host arbitrary JavaScript execution in the embedding page. - **Trigger:** A consumer loads and evaluates a15tmjvr.js in a browser. - **Impact:** Remote-controlled code executes in the browser context of any page that includes the asset. - **Evidence paths:** package.json, a15tmjvr.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T20:42:58.747Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote module fetch followed by new Function execution - **Attack narrative:** When the asset is loaded in a browser, it bootstraps itself, fetches JavaScript module text from an obfuscated base URL, and passes that text to new Function(). The package omits normal npm entrypoints and presents only this opaque loader, preventing consumers from assessing the remotely supplied behavior. - **Rationale:** The package contains a concealed remote code loader whose downloaded response is directly executed. Although it has no install hook, this is a concrete arbitrary-code execution surface for users who load the supplied asset. - **Files touched:** a15tmjvr.js ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** a15tmjvr.js is deliberately obfuscated., Browser bootstrap fetches remote module text., Fetched text is executed with new Function()., No package entrypoint or lifecycle hook declares this loader. - **Evidence against:** No install lifecycle scripts are declared in package.json., No local credential or filesystem access is visible. ## Public findings ### 1.
