What Are the Different Kinds of Malware? Find All Details Here!


If available data and numerous detailed studies are to be believed, no business is immune to cyberattacks. Small businesses are probably more vulnerable than big companies and brands, because they don’t spend on cybersecurity as much as they should. Malware is one of the common cybersecurity concerns, and there are varied kinds of malware that hackers use for infecting systems, to gather data, or encrypt resources. In this post on cybersecurity, we are discussing more on the different kinds of malware. 

  • Trojan. Also called Trojan horse, Trojan looks like genuine software but often is malware in disguise. Trojan are used for stealing data, installing backdoor entries, or often to just infect systems. The worst part is Trojan malware often seems very legitimate, like a simple free OS update, or music app. 
  • Virus. Virus is another common form of malware that will insert its code and infect numerous folders within a system. The purpose of virus is to typically steal information, but some computer viruses are designed to bring systems down. 
  • Worm. In many ways, worms are similar to viruses, but don’t spread from one folder or program to others. Worms do infect systems and damage devices, and no user action is required, once the worm has been installed. 
  • Ransomware. True to the name, ransomware is about getting a ransom. Once ransomware is installed, hackers will hold data and systems captive through encryption, and they will block access to these resources, unless a ransom is paid. Typically, hackers ask for ransom payments through bitcoin. Ransomware is often installed through suspicious attachments and email links. 
  • Spyware. Spyware is designed to spy on the user. Once installed, Spyware will check actions, gather data, including personal and financial information, which hackers then use for various purposes. 
  • Adware. If a user ends up installing adware on their system, they will start seeing unusual ads and promotions. Compared to other malware, adware doesn’t steal data, but can impact system and device performance. 

Preventing malware attacks

Malware is often installed by employees, who don’t follow safe browsing practices, or are unaware of their actions. If your company is particularly concerned about malware attacks, consider hiring cybersecurity experts to train employees and executives. Make them aware of suspicious emails, aspects like social engineering, and how malware can be detected. A proactive stance and scanning networks and devices regularly can help in preventing malware attacks. Also, keep an eye on all networked devices, including IP cameras and video surveillance systems, which are often on the radar of hackers.
