What Is Card Cracking

Card cracking is a type of automated threat identified by the OWASP organization that has become increasingly prevalent in the financial industry. Card cracking involves the use of automated tools and techniques to obtain access to people’s financial accounts and steal money. In this blog post, we will explore what card cracking is, how it works, and the measures that can be taken to prevent it.

About Card Cracking

Card cracking is typically carried out by fraudsters who lure victims into providing their bank account details or debit card information. They may use social media, email, or text messages to offer fake job opportunities or easy ways to make money. Once the victim provides their banking information, the fraudsters use automated tools to test the account credentials and gain access to the victim’s account.

Once the fraudsters have access to the victim’s account, they can carry out a variety of fraudulent activities, such as transferring funds to other accounts, making unauthorized purchases, or withdrawing cash. These activities can result in significant financial losses for the victim.

Steps to mitigate Card Cracking threats

Steps to mitigate card cracking threats

To prevent card cracking, web application developers can take several measures, such as the following –

Implement multi-factor authentication (MFA):

MFA is one of the most effective ways to prevent card cracking. It involves requiring users to provide more than one form of identification to access their account, such as a password and a fingerprint or facial recognition. This makes it much more difficult for fraudsters to gain access to a user’s account.

Educate users:

Users should be educated on the risks of card cracking and how to protect themselves. They should be advised to never provide their banking information to anyone they do not know, and to never respond to unsolicited emails or messages.

Monitor user behavior:

Fraud monitoring involves monitoring user behavior and flagging suspicious activity for further investigation. This can be done using automated tools that detect unusual account activity and notify the user and the financial institution.

Implement fraud detection tools:

Financial institutions can use fraud detection tools to identify and prevent card cracking attempts. These tools use machine learning algorithms to analyze user behavior and detect fraudulent activity.


Card cracking is a significant threat to people’s financial security. It is essential for web application developers and financial institutions to take appropriate measures to prevent card cracking by implementing security measures, educating users, and working with law enforcement agencies to identify and prosecute fraudsters. By taking these steps, businesses and individuals can protect their investments and ensure that their financial accounts are secure.
