Final answer:
A rootkit is the type of malware that allows hackers to bypass authentication and control a compromised system. These malicious tools are designed to be hidden and can be installed through phishing attacks or exploiting system vulnerabilities. Users should employ strong security practices to defend against such threats.
Step-by-step explanation:
Types of Malware and Authentication Bypass
The type of malware that allows an attacker to bypass authentication and gain access to a system is often referred to as a rootkit. Rootkits are designed to hide their existence and activities from the user and operating system, giving attackers remote control of the compromised system. Hackers use a variety of tactics to infiltrate systems, such as phishing schemes where they trick users into clicking on malicious links or divulging sensitive information. This can lead to the installation of malware, including rootkits, which can give an attacker full control of a system, bypassing the usual authentication required to access sensitive functions or data. It's essential for individuals and organizations to be vigilant and use comprehensive security measures like robust passwords, up-to-date anti-malware software, and regular system checks to protect against such threats.
