I have seen a lot of YouTuber making refer bypass and tasks bypass script of any application. Actually they are getting our database details and Queries from application. Is there any way to prevent it?

There are several steps you can take to secure MySQL data of an application from hackers:

  1. Use Strong Passwords: Use strong passwords for all user accounts that access the database. The password should be at least 8 characters long and should contain a mix of uppercase and lowercase letters, numbers, and symbols.
  2. Limit Access: Limit access to the MySQL database by only allowing connections from trusted sources. For example, you can limit access to the database to only a specific IP address or range of IP addresses.
  3. Use SSL Encryption: Use SSL encryption to encrypt data in transit between the application and the MySQL server. This will prevent hackers from intercepting the data as it travels over the network.
  4. Use Firewall: Use a firewall to block unauthorized access to the MySQL server. A firewall can prevent attackers from accessing the server by blocking incoming traffic from unknown IP addresses.
  5. Keep MySQL Updated: Keep the MySQL server and any associated software up-to-date with the latest security patches and updates. This will ensure that any known security vulnerabilities are patched and will prevent hackers from exploiting them.
  6. Use Least Privilege: Use the principle of least privilege when assigning privileges to database users. This means giving users only the privileges they need to perform their job and nothing more. This will limit the damage that a hacker can do if they manage to gain access to a user account.
  7. Regular Backup: Regularly backup the MySQL database to ensure that data can be restored in the event of a security breach or data loss.

In addition to the steps outlined in the previous answer, optimizing your PHP scripts can also help to improve the security of your MySQL database. Here are some best practices for optimizing PHP scripts for security:

  1. Use Prepared Statements: Use prepared statements to prevent SQL injection attacks. Prepared statements ensure that user input is properly sanitized and prevent malicious code from being injected into your MySQL database.
  2. Validate User Input: Validate user input to ensure that only valid data is entered into your MySQL database. This can help to prevent malicious code from being inserted into your database.
  3. Use PDO: Use PHP Data Objects (PDO) to access your MySQL database. PDO provides a more secure and efficient way to access MySQL databases than the traditional MySQL extension.
  4. Disable Display Errors: Disable the display of errors in your PHP scripts to prevent sensitive information from being displayed to users or hackers.
  5. Use Error Logging: Use error logging to capture and log errors that occur in your PHP scripts. This can help you to identify and fix security vulnerabilities in your code.
  6. Use Cryptography: Use cryptography to encrypt sensitive data before storing it in your MySQL database. This can help to protect your data from hackers who may gain access to your database.
  7. Use HTTPS: Use HTTPS to encrypt data in transit between your PHP scripts and the MySQL database. This can help to prevent hackers from intercepting and stealing sensitive data as it travels over the network.

By following these best practices for optimizing your PHP scripts for security, you can help to ensure that your MySQL database remains secure and protected from hackers.

I know where you can purchase a ready made rewarding app with tons of features and fully secured in very affordable price, but I’m not giving this information for free.

Right :smile: You can use it too, it even knows app inventor

I’d refrain from using ChatGPT for serious work like this. Although it does know a lot, deep down, you find that it does not know a lot. It confuses blocks and builders together, even mixing Java with AppInventor or making up components.

This is also kind of plagiarism as you cited information without mentioning the source.
