How are rootkits used in malware attacks?

### REPLY:
Rootkits are powerful tools used by advanced hackers to gain full control over a victim's system. They can be used to steal sensitive information such as login credentials, credit card details, and personal data. By hiding their presence and activities, rootkits can remain undetected for extended periods and allow hackers to maintain persistent access to the compromised system. It is crucial to have robust security measures in place and educate users on the dangers of rootkit infections to prevent data breaches and unauthorized access.
