What happens during a SQLi attack?

A. A malicious actor uses SQL to get the database to reveal its contents. B. Nothing happens as this is an old form of attack and no longer relevant because of newer cybersecurity protocols. C. Malicious SQL statements are placed somewhere within a web page or application’s input or URL. D. Hackers can gain access to sensitive data, such as PII, credit card information, and login credentials. E. This is considered a low-level attack and not destructive on a large scale so typically the most an attacker can do is render web pages differently to an end user.

• All options are correct.

• B only

• D only

• A, C, and D
