What does malware do? What is its purpose? Here’s a short introduction to the menace of the internet.
‘Malware’ is a combination of two words – malicious and software. Viruses, ransomware and spyware are examples of malware, and the name covers any software written with intent to damage devices or steal data.
Even if we don’t know how it works, we all know that software is the information that makes programs run on our computers and mobile devices. And most software is built with good intentions. But not all.
Malware is malicious software. It sneaks, uninvited, onto your computer or device and does bad things. And there are different kinds with different purposes. There’s mostly annoying malware, like pop-up ads. But there’s also more dangerous kinds, like programs that lock up a device until ransom is paid, or others that steal sensitive information like passwords or credit card numbers.
Types of Malware
Automatically displays unwanted ads, sometimes luring users to malicious websites.
Remote Access Trojan (RAT) Opens a back door to a computer so it can be controlled remotely, giving an external administrator access to all the computer’s functions and data.
Locks up users’ computers until ransom is paid.
Spies on users’ activity and reports sites you visit and other sensitive information to outsiders.
Invades a network of computers and takes directions from a central server. They may steal information from compromised computers or collectively launch Denial-of-Service (DoS) attacks.
