Attackers Use QR Codes to Bypass Browser Isolation for Malicious Communication

by Justin Erickson

Cybersecurity researchers have discovered that attackers are leveraging QR codes to bypass browser isolation security tools, enabling malicious command-and-control (C2) communications. By embedding malicious links in QR codes, threat actors trick users into scanning them with mobile devices, which bypasses browser isolation. Moral of the story: Don’t scan any suspicious QR codes, and implement additional security controls for your mobile devices to detect and block malicious activity. This emerging attack method highlights the need to keep up with updated cybersecurity measures, as threat actors continue to adapt.
