In 2019, over 811 million malware infections were reported, according to the Cyber Security Report. Cybercrime has increased up to 620% during the COVID-19 pandemic, with phishing emails being the most popular way to deliver malware infections.
Another report by the Internet Security Threat unveiled that more than 244 million new variants of malware infections have emerged.
As malware infections continue to rise, it’s critical to understand the basics of malware, as well as the things that can be done to protect users, networks, and crucial business data. But first, what is malware?
Malware 101: The Basic Definition
Malware or ‘malicious’ software is typically curated with the intent to exploit, disable, or damage systems, devices, and networks. It’s widely used to bypass access controls, steal data, compromise device functions, cause harm to devices and networks they’re connected to.
Understanding Some Common Types Of Malware
#1- Viruses
Viruses are specifically designed to damage the target device by reformatting the hard disk, corrupting data, or causing the system to shut down.
They’re also often used to harm networks and devices, steal information, render advertisements, steal money, create botnets, and more. Viruses in computers require human interaction, but viruses in other smart devices can quickly spread through internet downloads and email attachments.
#2 Worms
Worms are one of the most common types of malware infections. They spread over the networks to exploit the operating system’s vulnerabilities. It’s a standalone program that can replicate itself to infect other devices, requiring no particular actions from anyone.
They spread fast and are used to execute a payload, a code created specifically to damage a system. Payloads can easily encrypt data for ransomware, delete files on host systems, delete files, create botnets, and steal information.
#3 Trojan Horse
Trojan horses can enter a system disguised as a harmless program or file. It’s designed to trick people into downloading or installing the malware.
The minute you install the Trojan, cybercriminals gain access to the system. They can install additional malware, steal or destroy data, modify files, steal financial information, conduct DoS (Denial of Service) attacks on targeted web addresses,monitor user activity, and more.
