    Phishing Attack on 2FA

    Understanding the Attack

    Phishing attacks are a type of social engineering attack where an attacker attempts to trick a victim into divulging sensitive information such as login credentials or 2FA codes. In the context of 2FA, phishing attacks aim to bypass the second factor of authentication by exploiting the victim’s trust in a legitimate-looking login page.

    How the Attack Works

    When a victim clicks on a phishing link or receives a phishing email, they are redirected to a fake login page that mimics the real one. The fake page may appear identical to the legitimate one, making it difficult for the victim to distinguish between the two. The attacker’s goal is to capture the session cookie that is created when the victim enters their credentials, including the 2FA code.

    Capturing the Session Cookie

    The session cookie is a small piece of data that is stored on the victim’s device and is used to authenticate the user. When the victim enters their 2FA code correctly, a session cookie is created and stored on the device. The attacker captures this cookie and stores it for later use, allowing them to bypass the 2FA requirement in the future.

    Types of Phishing Attacks

    There are several types of phishing attacks that can be used to bypass 2FA, including:

  • Spear phishing: Targeted phishing attacks that focus on specific individuals or groups. Whaling: Phishing attacks that target high-level executives or decision-makers. Smishing: Phishing attacks that use SMS or text messages to trick victims into divulging sensitive information.
