Matrix Push C2 Uses Browser Notifications for Fileless, Cross-Platform Phishing Attacks
Bad actors are deploying Matrix Push C2, a fileless command-and-control (C2) framework, to distribute phishing links via browser notifications. The tool leverages trusted branding and fake alerts to trick users into clicking malicious links, bypassing traditional security measures.
Why This Matters
Browser notifications, designed for legitimate purposes like real-time updates, are being weaponized to bypass endpoint defenses. Unlike traditional malware requiring file downloads, Matrix Push C2 operates entirely in memory, evading detection by antivirus software. The attack’s cross-platform nature—working on any browser that supports web push notifications—amplifies its reach, with threat actors selling access via Telegram for as little as $150/month. The cost of containment and reputational damage from such attacks could exceed $1 million per incident, according to industry estimates.
