WAEVO : Transforme conversas em oportunidades.

AI Security Review

Evidence context: threat category none; evidence quality strong.

The WAEVO extension manages WhatsApp conversations and automations. Its description explicitly states this purpose. The extension connects to app.wascript.com, which is the backend for WA Script, a known WhatsApp automation platform. This network endpoint aligns perfectly with the extension's stated functionality. The extension declares no host permissions, restricting its reach to its own interface and the specific backend it communicates with.

The findings summary shows 1172 total alerts. The nature of these alerts reveals standard false positive patterns. The 418 IoC findings are dominated by design tokens and property access chains. The network endpoints list includes border.radius.circle, color.border.accent.orange, btn.glass, and calls.function.arguments.delta. These are CSS variables and JavaScript object properties extracted by the XIOC tool. They do not represent actual network traffic to suspicious domains. Legitimate infrastructure like api.atlassian-us-gov-mod.com and api.statsigcdn.com are standard SaaS dependencies used for authentication and feature flagging.

Two obfuscation findings exist. The OBFUSCATION-LARGE_BASE64 alert in funnil/assets/js/0c7a903c-6665-4db4-bec2-13ad7e8d3381.9ZuTaqvp.js points to a large base64 encoded string. In modern web applications, base64 strings frequently encode custom web fonts, SVG icons, or localized configuration payloads. The OBFUSCATION-FUNCTION_INDIRECT alert in content/assets/js/v_7_4_3_85_81c9fdf6-5aa3-4e05-88c1-f94c9eaf6920253.js is typical of minified or transpiled JavaScript output from build tools like Webpack or Babel. Neither finding contains malware signatures.

The 730 code-smell findings are all low severity. They consist of generic YARA rules matching standard Node.js and browser APIs. These rules fire on almost any non-trivial JavaScript codebase and carry no diagnostic value for identifying actual threats. The 21 network findings simply log standard fetch and socket.io calls made by the frontend application to its own backend.

A skeptic might point to the sheer volume of 1172 findings and the presence of base64 encoded data as evidence of a hidden payload. Base64 can indeed hide malicious scripts. However, the base64 string resides in an assets directory alongside versioned JavaScript files, which is the standard location for bundled frontend resources. Furthermore, the complete absence of malware signatures, combined with the presence of hundreds of CSS design tokens misidentified as domains, confirms the scanner is tripping over the extension's UI framework and build artifacts. The extension does what it says it does, and the noise is entirely generated by automated pattern matching against benign web development practices.

Key Reasons

• IoC extractor misidentifies CSS design tokens like border.radius.circle as network domains
• OBFUSCATION-LARGE_BASE64 in funnil assets is a standard embedded font or icon payload
• Zero malware signatures detected across the entire codebase
• Network endpoint app.wascript.com matches the extension's stated WhatsApp automation purpose
• 730 code-smell findings are low severity generic YARA matches on standard browser APIs

False Positive Considerations

• XIOC extractor parsing CSS variables and JS properties as domains
• Base64 encoded assets triggering obfuscation detectors
• Generic YARA code-smell rules matching standard web APIs
