Matrix Push C2: Browser Notification Exploits Drive Fileless, Cross-Platform Phishing

Threat actors are increasingly leveraging browser notifications to facilitate phishing attacks through a new command-and-control (C2) platform, Matrix Push C2. This fileless, browser-native framework employs push notifications, deceptive alerts, and link redirects to deliver malicious payloads across multiple operating systems. Security researchers emphasize the cross-platform risk and the importance of robust browser security policies to mitigate these advanced attack vectors.
