Types of Malware Threats (Continued)
Adware
Although not as destructive as other types of malware, adware bombards users with unwanted advertisements. The effects could be decreased system performance and potential security risks. In some cases, adware collects user data to target ads more effectively, infringing on privacy.
Rootkits
Rootkits are stealthy malware designed to hide their presence on the system. They give attackers persistent control over the device, often evading detection by antivirus software. Rootkits are used to steal sensitive information or facilitate further attacks.
Keyloggers
Keyloggers record keystrokes to capture sensitive information like passwords, credit card numbers, or private messages. The data is then sent to the attacker for exploitation. This is one of the reasons why you should always make online purchases from trustworthy websites. Visiting unscrupulous websites may unknowingly download a keylogger software into your computer or smartphone.
Botnets
A botnet is a network of compromised devices (bots) controlled by an attacker. Botnets can be used to launch distributed denial-of-service (DDoS) attacks or send spam. DDoS is one of the common methods used by cyber attackers to disrupt the operations of websites or computer systems.
Fileless Malware
Unlike traditional malware that is stored on disk, fileless malware operates in a system’s memory, making it extremely difficult to detect. It exploits legitimate software and vulnerabilities to carry out its attacks, often leaving no trace once it exits memory.
