How do hackers crack bank cards and passwords?

Hackers crack bank cards and passwords through constant collisions and guesses.

1, through the loopholes in the website, use a self-made program to capture the personal identity information of citizens, and then import this information into the batch login program written by yourself, and the account information with the same withdrawal password as the online banking login password and email password will collide.

2. Visit the internal website of the bank and the electronic documents of depositors' related information: depositor's ID number, bank card number, mobile phone number and other related information. According to the digital elements such as the depositor's ID number and mobile phone number, through the online banking system, the depositor's password is cracked through constant collision and speculation.

Therefore, when setting the bank card password, don't use telephone number, mobile phone number, ID number, birthday, QQ number, email number and other information that can be easily obtained by others to set the password.
