In this article, we will talk about the most common types of cyberattacks.
We call cyberattack any offensive maneuver employed by individuals or whole organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices. These attacks try to hack into a system using one or several digital acts, usually from an anonymous source, to steal, alter, or destroy a specified target.Among the common types of cyber attacks we find the following:
Malware
Malware is any software that intentionally performs malicious actions in a system without the user’s knowledge. Viruses, worms, and trojan horses are different kinds of malware.
Virus
A computer virus is a small script of code that, when executed, replicates itself by modifying other computer programs called hosts and inserting its code to alter how a computer operates. Of course, since this is a type of malware, it is all done without the permission or knowledge of the user.
Worm
A computer worm is a standalone malware program that replicates itself to spread to other computers. This differs from a virus because the virus needs a host program, but the worm does not. A worm often uses a computer network to spread itself, relying on security failures on the target computer to access it. Once there, it will try to scan and infect other computers.
Trojan Horse
A Trojan Horse Virus is malware that downloads onto a computer disguised as a legitimate program. It typically gets hidden as an email or free-to-download file attachment and then transfers onto the user’s device. Once downloaded, the malicious code will execute the task the attacker designed it for, such as spying on users’ online activity or stealing sensitive data.
