What are some advanced types of spyware that are utilized by intelligence companies?

There are many advanced types of spyware used by intelligence companies.  https://zerogov.net/?p=1525 A few of these include keyloggers, which record every keystroke made by a user; remote access tools, which permit an attacker to acquire control of a victim's maker; and malware that is created to steal delicate information or passwords.

One especially sophisticated type of spyware is referred to as a rootkit. Rootkits are created to conceal themselves from detection, and can be very tough to eliminate once they have been installed on a system. They are typically used to give an assaulter complete control of a victim's maker, allowing them to spy on the user, or perhaps take control of the device remotely.

Another sophisticated type of spyware is called a botnet. A botnet is a network of contaminated computer systems that can be managed remotely by an attacker. Botnets can be utilized to launch dispersed denial of service (DDoS) attacks, or to send spam and phishing e-mails. They can also be utilized to spy on users, or to take delicate data.

Spyware is becoming increasingly advanced, and intelligence companies are constantly evolving their tools and techniques to stay up to date with the most current dangers.
