Malicious software—or malware—is used by threat actors to access and infect a computer or network while avoiding being detected. Certain terms such as viruses, adware, spyware, ransomware, worms or Trojan horses; are all different types of malware that can cause severe damage your computers. Cybersecurity vendors are constantly on the lookout to locate these dangerous codes and put an end to them before they cause significant damage.

All forms of malware are extremely treacherous once they infiltrate a device, but the way malware functions differ is dependent on the type of malware. As you look to better safeguard your most critical business assets, we have provided a list of several types of malware and short definitions for how they work that will help inform your planning for stronger defense-in-depth. Of course, Cyber1 Security is happy to further discuss your specific security needs and explore services that will help best protect your business. Let’s review:
