Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. When the bundled browser script is loaded on a matching theme page, it blocks the page with a deceptive overlay and prevents normal interaction. No network or local-system access was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-07T08:17:49.515Z - **Finished:** 2026-09-07T08:18:45.356Z - **Download time:** 509 ms - **Static scan time:** 25 ms - **AI review time:** 55306 ms - **Total time:** 55841 ms The recorded confidence comes from the underlying analysis.

No network or local-system access was identified. - **Trigger:** Loading the JavaScript as a browser theme chunk. - **Impact:** Denial of normal website use and concealed page-content replacement. - **Evidence paths:** chunk-original.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T08:18:45.356Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated DOM overlay and input suppression. - **Attack narrative:** The payload runs immediately in a browser context. It creates a fixed full-screen overlay, modifies a selected theme banner, disables scrolling and page pointer events, and captures keyboard input to cancel it. It keeps the overlay reachable through a random protected window property, then removes its own script tag. The package has no installation hook or exfiltration code, but the included browser payload is intentionally obfuscated and directly disrupts a host website. - **Rationale:** This is an intentionally obscured browser denial-of-service payload that alters and locks a host page when deployed. The absence of installation hooks limits the trigger but does not neutralize the concrete malicious behavior. - **Files touched:** chunk-original.js, dist/theme-bundle.chunk.7.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The browser payload creates a full-screen, highest-layer overlay and replaces content in a targeted page banner., It disables page scrolling and pointer input, while cancelling all keyboard events., It stores the overlay under a random, non-configurable window property and removes its own script element., Strings and identifiers are deliberately obscured in the distributed payload. - **Evidence against:** package.json has no install lifecycle hook., No network, credential, environment, or local-file access was found., The declared main file is absent, so ordinary package import does not load the browser payload. ## Affected versions and remediation This report applies to theme-bundle.chunk.7.js@1.0.6. - Avoid installing theme-bundle.chunk.7.js@1.0.6. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
