QR Codes Used by Attackers to Bypass Browser Isolation
/ 1 min read
📲 Cyberattackers exploit QR codes to bypass browser isolation security. Researchers from Mandiant have demonstrated a proof-of-concept that allows cybercriminals to circumvent three types of browser isolation by using machine-readable QR codes. This technique enables attackers to send commands from a command-and-control server to a victim’s device, despite browser isolation’s protective measures against phishing and browser-delivered attacks. The method involves rendering a webpage that displays a QR code, which the compromised device can read to execute commands. While this approach shows potential vulnerabilities, Mandiant still advocates for browser isolation as a critical defense mechanism, emphasizing the need for a comprehensive cybersecurity strategy that includes monitoring for unusual network activity.
