Resku is a browser extension (Chrome, Edge, Brave, Arc) that evaluates web pages with a scoring system from 0 to 100 to detect phishing and fraudulent sites before users enter sensitive information like passwords or payment details. It performs local DOM analysis and sends limited signals (URL, domain, technical indicators) to an API for scoring refinement. The extension uses over 120 rules and approximately 190 checks, including detection of typosquatting and malicious scripts such as keyloggers and obfuscated code. The developer is seeking French testers to provide feedback on false positives/negatives, alert clarity, performance, and privacy. The project is personal, free, and does not require account creation or payment details.

No direct security threat or vulnerability is described. The content relates to a security tool aimed at phishing detection, not an exploit or malicious campaign. There is no indication of active exploitation or harm. The impact is positive in terms of potential phishing protection if the tool is effective.

No mitigation actions are required as this is not a vulnerability or threat but a security tool in beta seeking testers. Users interested in phishing protection may consider evaluating the extension but should exercise caution with beta software and verify trustworthiness independently.
