Blind SQL Injection Attack
A Blind SQL Injection Attack is a type of attack that hackers use to access a database by taking advantage of a vulnerability in a website’s code.
When a website allows users to input information, such as search queries or login credentials, hackers can use that input to inject malicious code into the website’s database. This code can then be used to extract sensitive information, such as usernames and passwords, from the database.
The term “blind” refers to the fact that the attacker typically does not have direct access to the contents of the database. Instead, they must infer the contents of the database through the responses they receive from the website to their input queries.
For example, if a hacker were trying to use a blind SQL injection attack to retrieve a user’s password, they might input a value that they suspect is part of the password (such as the first letter), and then observe whether the website’s response is different depending on whether or not the guess was correct. Based on this feedback, the attacker can iteratively refine their guess until they are able to retrieve the full password.
To prevent blind SQL injection attacks, website developers should ensure that their code is properly validated and sanitized to prevent malicious user input from accessing the underlying database.
