Types of Malware
Generally, malware is a form of destructive software designed to interfere with the normal functioning of a computer. It seeks to damage, disable or steal information. It may be delivered through malicious websites, emails or downloads.
There are many types of malware, but they all share some common traits. These include the ability to encrypt user data and steal personal information. They can also spread through file-sharing and network connections.
Infecting a computer with a Trojan horse is one of the most dangerous types of malware. The Trojan will usually appear as a legitimate software program and will take control of the user’s computer. It may also hide in games, software patches and phishing emails.
Another common type of malware is a worm. A worm is a self-replicating computer program that spreads without the user’s involvement. It can infect a whole network or simply copy itself from one system to the next.
Malware has become more complex in recent years. It can use social engineering to trick users into installing it. It can be delivered through malicious emails, USB drives or popular collaboration tools. Malvertising, a form of online advertising, can also be used to spread malware. Malvertising involves injecting malicious code into legitimate websites.
Another common form of malware is cryptojacking. This malicious cryptomining involves using computing power to confirm transaction. It can be delivered through spam emails and social media.
Another common type of malware is spyware. This type of malware secretly tracks user activity and reports back to its creator.
