Threat Intel FAQ

How can my organization detect if our payment pages are being targeted by these kits?

Continuous monitoring of web application integrity is essential. By using advanced attack surface management and source code review, you can detect unauthorized scripts or modifications that indicate an attacker is attempting to inject phishing components into your legitimate payment flows.

Does 3DS provide enough protection against these new toolkits?

While 3DS is a standard security measure, modern toolkits are designed to bypass or manipulate these processes. It is critical to supplement standard compliance protocols with proactive security testing to ensure that your specific implementation remains resilient against sophisticated automated attacks.
