Practical Cyber Hacking Skills for Beginners - Web Attack - SQL Injection

The video tutorial explains SQL injection attacks, a common threat to databases, and demonstrates how they can extract sensitive information, delete data, or inject malicious code. It provides examples using a banking login page and a weather station app, highlighting the vulnerabilities in poorly written SQL code. The tutorial also covers methods to prevent such attacks, including parameterized statements, escaping inputs, and sanitizing inputs, ensuring database security.

What is one of the main targets of SQL injection attacks?

• Web servers

• SQL databases

• User interfaces

• Network routers

Which of the following is a potential consequence of an SQL injection attack?

• Enhanced data encryption

• Improved website performance

• Extraction of sensitive information

• Increased user traffic

In the banking login page example, what caused the syntax error?

• An invalid username

• A single quote in the password

• A missing semicolon

• Incorrect email format

What does the 'dash dash' (--) in an SQL injection attack do?

• Encrypts the SQL query

• Adds a comment to the SQL code

• Ignores the rest of the SQL statement

• Executes a loop in the SQL code

In the weather station app example, what does '1=1' signify in SQL?

• A false condition

• A true condition

• A null value

• A syntax error

How can SQL injection attacks be executed without direct input fields?

• By selecting from a range of options

• By using a different database

• By using SQL comments

• By encrypting the SQL query

Which method involves ensuring inputs are treated safely by the database?

• Data encryption

• User authentication

• Parameterized statements

• SQL comments

What is the purpose of escaping inputs in SQL?

• To improve query performance

• To prevent SQL injection

• To ignore invalid inputs

• To enhance data encryption

What does sanitizing inputs help prevent?

• SQL injection attacks

• Data redundancy

• User authentication errors

• Network congestion

Which of the following is NOT a method to prevent SQL injection?

• Escaping inputs

• Parameterized statements

• Using SQL comments

• Sanitizing inputs
