Injection

The video tutorial discusses the risks of injection attacks, particularly SQL injections, in web applications. It explains how attackers can manipulate data to execute unintended commands, potentially gaining control over the backend. Examples of SQL injection attacks are provided, demonstrating how malicious queries can alter or delete database information. The tutorial concludes with strategies to prevent such attacks, emphasizing the importance of input sanitization, using safe APIs, and running commands with minimal privileges.

What is a common method attackers use to manipulate web applications?

• By changing the website's layout

• By modifying the user's browser settings

• By injecting data to trick the interpreter

• By altering the server's hardware

In an SQL injection attack, what can an attacker achieve by injecting '1=1' into a query?

• Delete all records in the database

• Retrieve all records from a table

• Crash the database server

• Change the database schema

What is the result of executing the SQL query 'DROP TABLE learners'?

• It selects all records from the learners table

• It updates the learners table

• It deletes the learners table

• It creates a new table called learners

Which of the following is a recommended practice to prevent SQL injection attacks?

• Using safe APIs and input sanitization

• Running all commands with admin privileges

• Storing passwords in plain text

• Allowing all user inputs without validation

Why is it important to run commands with minimal privileges?

• To ensure faster execution of commands

• To allow users to access all database features

• To reduce the cost of database operations

• To prevent unauthorized actions like 'DROP TABLE'
