Malware Types and How to Protect Your Organization against Them

| Updated on March 27, 2024

Malware is multiplying very rapidly. According to DataProt, 560,000 new malware are discovered in the world daily. Some are crude, while others are quiet in their implementation. Cybercriminals sometimes use Malware to play a light-hearted practical joke or extort money from a company. The use cases are endless. The malware issue is so pertinent that every business will likely be the target of a malware attack within the next ten years. So let’s dive deep into what are Malware exactly and how to prevent them from causing danger. 

What Exactly is Malware?

Malware is any software that has the intention of causing harm to a system or device. The term encompasses computer worms, trojans, and bots.

Firewalls are an effective method of protection against Malware. Most firewalls rely on a list of periodically updated Malware to reflect new malware detections. You can then report this Malware to the FBI, CISA, or Secret Service in the United States.

Malware types

Even though there are thousands of Malware out there, we will describe the most common malware types:


Computer infrastructure and systems are “infected” by viruses. As their name goes, they replicate and spread to other digital devices they come into contact with. For example, a virus can be acquired by downloading a file from a malicious website. They can also be spread via malicious email attachments. Alternately, viruses can also be transmitted physically. For example, a cybercriminal may leave an unlabeled USB drive in or near a targeted business. Consequently, an unsuspecting employee may end up plugging it into their computer to determine who owns it.


Worms are very similar to viruses, but one key distinction is that their damage is caused by repeated replication. This eventually exhausts a system’s resources. When all resources have been allocated, the system fails. While viruses infect new systems, worms replicate to render a system inoperable. Some worms are even carried to new systems by viruses. Others have their virus-like method of propagation. In essence, a worm can be categorized as a virus.


They are Malware that disguises themselves to gain access to a computer system. The assumption here is that the carrier is a reliable file or piece of software. Administrators will execute this file with the expectation that it is virus-free. An excellent example is a free software that performs a utility such as recompiling a file into a different format. The software may contain a trojan that becomes active once installed. The trojan may also be added to the file by an online compiler.


The malware that attempts to extort money from a target is known as ransomware. The majority function by encrypting computer files or systems essential to the operation of a business. There isn’t any guarantee that cybercriminals will unlock your files. These hackers utilize cryptocurrencies as a form of payment. Because it typically conceals the recipient.

Ransomware poses a grave threat. These attacks can result in significant collateral and monetary damage. Numerous complex examples of infectious ransomware, including those that propagate through supply chains using vendors as the entry point. 

Bots and Botnets

Bots are frequently encountered during internet searches. For example, a bot can be used to “web-scrape” websites. On the darker side, cyber criminals employ bots and botnets to engage in online stalking. Cybercriminals can also employ bots and botnets to bring a website down by bombarding it with repeated queries. When an IP address is attacked, it is typically prevented from submitting a query for a few seconds. This allows the server to continue processing legitimate requests. 

How to Defend Yourself Against Malware

Different types of Malware will necessitate distinct defensive strategies. To save time, you should ensure that every machine has a firewall and antivirus software. In addition, consider options with ad-blocking, anti-malware, and anti-spyware capabilities. You should also compare malware lists between solutions to determine which catches more Malware. The more extensive the list, the better. Consequently, the following are factors to consider when defending against Malware.

Implement a Malware Protection System

As part of the firewall, an anti-malware solution must be able to inspect or sniff individual packets. The majority of firewalls are implementing this feature to aid in malware detection.

Assess Your Safety

Bring in penetration specialists or use your own to determine if they can gain access to your network if your organization is large enough. They can identify which attack surfaces require additional attention. As your business grows, add or remove attack surfaces regularly.

Add Additional Security and Permissions Layers

MFA (multi-factor authentication) is essential. Additionally, you should apply it to every application you employ. This can aid in preventing numerous attacks, as Malware will be unable to circumvent it in most cases, except injection attacks.

Ensure you also implement a spam filter to ensure that you don’t click on malicious links.
