What is a difference between out-of-band SQL injection attacks and bind SQL injection attacks?

The correct answer is A. Out-of-band SQL injection attacks use an application to dump retrieved data, and blind SQL. Out-of-band SQL injection retrieves data through an external channel, such as DNS or HTTP callbacks, which allows the attacker to extract information even when the primary application channel does not return results directly. Blind SQL injection cannot return data directly…

Explanation

Out-of-band SQL injection retrieves data through an external channel, such as DNS or HTTP callbacks, which allows the attacker to extract information even when the primary application channel does not return results directly. Blind SQL injection cannot return data directly; instead, an attacker infers database structure and content by observing how the application behaves in response to crafted inputs.
