Malware is malicious software that cybercriminals install on devices to exploit the victim’s personal or business network, device, and data. Malware impacts every kind of computer or mobile device. Some users think that they don’t have to worry about malware because they use a Mac, or they only install apps from official app stores. However, as you’ll learn, there are many kinds of malware that are becoming stealthier and harder to detect.
There are different types of malware that go beyond common computer viruses.
- Viruses are malicious programs that spread from device to device, usually by an attachment or file. Once on your computer, your device gets infected and the virus may control some of your computer’s functionality.
- Worms are malicious programs that don’t need user interaction to activate themselves. This malware is not attached to files. A security weakness often opens up the network or device to vulnerability for a worm to enter.
- Trojan Horses are applications that pose as legitimate software, but actually contain malware. This is often the gateway for cyber-attacks. Once malware is on your device, it can tamper with your security systems to invite more malware.
- Cybercriminals install Spyware to track your browsing habits, keystrokes, and other actions. It is very difficult to detect, so it can sit and collect data from your device for a long time.
- Adware is software that creates pop-up advertisements on your device. In some cases, it can also change your browser preferences. Adware will collect your browsing data to serve you more “targeted” ads but ends up flooding you with pop-up ads.
- Ransomware is malicious software that encrypts their victim’s data. It locks them out of their system, data, and files. Cybercriminals then ask for money in exchange for the release of data.
What are known as “Advanced Persistent Threats” are designed to stay active in a system for long periods of time so the bad actor can either gather data or use the computer for crypto mining, sending malicious emails or botnet activities. Most users will never know they are infected because the malware is designed to cover its tracks until it’s triggered.
Cybercriminals use malware for identity fraud, mining cryptocurrency, stealing credit card information, and more. The bottom line is that cybercriminals use malware for financial gain. If you don’t take proper steps to protect yourself against malware, you are vulnerable to attacks
Understanding malware is the first step in protecting yourself against this cyber-attack.
How Do I Know if I Have Malware?
In the current threat landscape, no personal computer should be used without endpoint protection. There are a few signs of malware that you can look out for to determine whether your computer has malware or not. Your computer will likely be acting “strange”. It could be slow computer performance or the browser redirects that give it away. You also might experience random pop-up ads, difficulties powering on your computer, or a lack of storage.
At the end of the day, it’s best to get an anti-malware software that detects and eradicates malware on your device.
How Do You Get Malware?
Cybercriminals look at any holes in your security and rely on you falling for one of their tricks. Generally, cybercriminals target you from two sources – internet and email. According to the Government of Canada’s Get Cyber Safe program, 94% of malware is received by email. However, there are many places that malware can hide. This includes downloaded movies, hacked websites that appear legitimate, email attachments and links, unofficial software, infected USB drives, and more.
Once you click on a compromised link or attachment, the virus gets triggered and activated. Most viruses copy themselves and spread through your files. They try to infect as much of the computer as possible.
How Do You Protect Yourself Against Malware?
In the current threat landscape, no personal computer should be used without endpoint protection. Get Cyber Safe reports that every 2 in 5 Canadians experience malware on their computers. However, the best way to deal with malware is to never get infected. Once it’s in a system it’s virtually impossible to say for 100% it has been eradicated. If you’re not using endpoint protection software stop reading now and turn it on.
Get endpoint protection for your device and follow these tips to protect yourself against malware.
