Why is it important to change default passwords to prevent Backdoor attacks?

Changing default passwords is crucial in preventing backdoor attacks primarily because default passwords are typically easily guessed or known by many individuals. Manufacturers often set standard passwords for devices and applications, which are generally listed in user manuals or online forums. Cyber attackers frequently exploit this common vulnerability by attempting to gain unauthorized access using these known default credentials.

When organizations or individuals neglect to change these default settings, they leave their systems open to attacks since anyone could potentially access the system and exploit it. Therefore, altering default passwords to unique, strong passwords is an essential security practice that helps safeguard systems against unauthorized access and potential data breaches.

The other options either do not reflect the reality of default passwords or do not directly address their security implications.
