Barracuda reveals phishing gangs using new QR code evasion tactics
Phishing attacks have become increasingly sophisticated, with cybercriminals constantly finding new ways to evade detection and trick victims into divulging sensitive information. In a recent threat report, Barracuda threat analysts have uncovered two innovative techniques being used by phishing gangs to help malicious QR codes evade detection in phishing attacks.
The report, which highlights the growing concern of QR code-based phishing attacks, reveals that attackers are using two new evasion tactics to bypass traditional QR code scanning systems. These techniques are designed to confuse and deceive even the most vigilant users, making it essential for individuals and organizations to stay informed about these emerging threats.
Technique 1: Splitting Malicious QR Codes
The first technique involves splitting a malicious QR code into two separate codes. This is done to confuse traditional QR code scanning systems, which are designed to read a single QR code at a time. By splitting the code, attackers can create a sequence of QR codes that are triggered in a specific order, allowing them to bypass detection by scanning systems.
In this technique, the attacker creates two QR codes, one containing the malicious payload and the other containing a decoy or a legitimate URL. The victim scans the first QR code, which appears to be legitimate, and is then redirected to the second QR code, which contains the malicious payload. This allows the attacker to evade detection by traditional scanning systems, which may flag the first QR code as suspicious but not the second.
Technique 2: Nesting Malicious QR Codes
The second technique involves nesting a malicious QR code within or around a second, legitimate QR code. This is done to mask the malicious QR code within a legitimate one, making it difficult for scanning systems to detect the malicious payload.
In this technique, the attacker creates a QR code that contains both the malicious payload and the legitimate QR code. The legitimate QR code may be a real URL or a decoy, designed to distract the victim from the malicious payload. When the victim scans the QR code, they are presented with a legitimate-looking URL or page, while the malicious payload is triggered in the background.
Consequences of QR Code Evasion Techniques
The consequences of these QR code evasion techniques can be severe, with victims potentially losing sensitive information, financial data, or even their entire identity. Phishing attacks that use these techniques can be particularly effective, as they often combine social engineering tactics with technical trickery to deceive victims.
The rise of QR code-based phishing attacks is also driven by the increasing use of QR codes in everyday life, from restaurant menus to event tickets. As QR codes become more ubiquitous, attackers are finding new ways to exploit them, making it essential for individuals and organizations to stay informed about these emerging threats.
Mitigating QR Code Evasion Techniques
To mitigate the risk of QR code evasion techniques, it is essential to implement robust security measures, including:
- Regularly update your QR code scanning app to ensure you have the latest security patches and features.
- Always scan QR codes from reputable sources, and be cautious of QR codes from unknown or suspicious sources.
- Verify the URL or destination of the QR code before scanning it.
- Use a QR code scanner that has built-in threat detection and alerts you to potential threats.
- Educate yourself and others about the risks of QR code-based phishing attacks and how to avoid them.
Conclusion
The use of QR code evasion techniques by phishing gangs is a growing concern, and it is essential for individuals and organizations to stay informed about these emerging threats. By understanding these techniques and implementing robust security measures, you can significantly reduce the risk of falling victim to QR code-based phishing attacks.
