A rootkit will contain malicious tools, including banking credential stealers, password stealers, keyloggers, antivirus disablers and bots for distributed denial-of-service attacks. OS developers and security researchers continue to improve operating systems and endpoint defenses to protect users from all types of malware, and their efforts have been especially effective against rootkits. Rootkit installation can be automated, or an attacker can install it after having obtained root or Administrator access. They install themselves as part of some other download, backdoor, or worm. The rootkits highlighted below are both significant in their development or impact.
