Cybersecurity attack using malware is already rising since a couple of years back. But that surged since the pandemic happened.
But what are some of the types of malware you need to look out for? Let us get to know them in this article.
Types of Cybersecurity Attack Using Malware
Viruses
Of course, you may have already heard about viruses. This is the most known type of malware. Some even call all types of malware a virus.
But that is not the case. Viruses change a legitimate host file without you knowing. Once clicked, you will also open the virus. Then, your other files will get infected.
Once that happens, it can be very hard to clean up. Even the best antivirus out there will have a hard time. The good thing is, pure viruses are now becoming rare.
Worms
Worms, unlike viruses, can self-replicate. It can latch to an email attachment. Once clicked, it can spread on your system within a short period.
Thus, harming your system. Further, it can even exploit your other files and make them do all the dirty work.
Trojans
Trojans can pretend to be a legitimate program, email, or website. But attached to it is a malicious program.
Once clicked, your computer gets attacked. But it is hard to defend against this one because it:
- is easy to write
- tricks you, which your firewalls and other defenses cannot stop
Adware
Adware is a malicious ad you see on some websites. Most of us have already encountered this.
Once clicked, it drives you to a fraudulent website. Then, these websites feature product promotions or will ask for sensitive data. But this is easy to remove.
Malvertising
Not to be confused with adware. But their similarity lies in the fact that it also is attached to an ad. Once clicked, two things can happen. This is where they differ.
One, it directs you to a malicious website. Or two, it delivers malware to your system. The most tricky part is that some malvertising does not even need to be clicked to be launched.
Spyware
Hackers use spyware to track the online activities of a well-known person, enemy, or loved one. So, the drive is the person.
But like adware, spyware is also easy to remove. Because it does not cause any damage, unlike viruses.
Ransomware
If spyware is about people, ransomware all about money. First, it will come as social engineering and trick you into clicking.
Once it enters your system, it encrypts all your data and keeps it hostage. Then, hackers will ask you for a ransom. Most of the time, they will ask for cryptocurrency. This can be hard to counter.
How to Keep Out of a Cybersecurity Attack Using Malware
So, how do you remove malware? Well, it is hard to remove them totally unless you are trained in malware removal and forensics.
Thus, the best thing you can do is take precautions before attacks happen. Like backing up your data. Once an attack does happen, you can format your drive and reinstall your programs.
