Matrix Push: How Browser Notifications Became a C2 Weapon in 2024
In early 2024, cybersecurity researchers reported that a threat actor group leveraged a new Command and Control tool—dubbed 'Matrix Push'—to hijack web browser notifications as an innovative phishing and persistence mechanism. Attackers delivered malicious payloads through deceptive websites, tricking users into allowing browser notifications. These notifications were abused to send phishing lures and exfiltrate user information, evading traditional network monitoring tools by using trusted browser channels. The campaign allowed remote control and persistent access to compromised endpoints, highlighting a shift toward social engineering at the browser level. Organizations targeted included enterprises in technology, finance, and professional services sectors, resulting in elevated risks of credential theft and lateral movement. This incident is especially notable for exploiting a trusted browser feature in new ways, bypassing established email and endpoint filtering controls. As browser notification-based attacks surge, security teams face increased pressure to adapt controls. The tactics highlight the urgent need for enhanced user awareness and modern segmentation/visibility solutions that can identify and mitigate covert browser-based C2 channels.
