With the increased use of technology, there come increased security risks. Hence, it is likely common that you experience some type of malware in your system. Without any security measures, the malware can damage your system.
In this article, you will get to know about what malware is, some of its common types, how it can affect your system, and what security practices you should follow to prevent different malware attacks.
What is Malware?
Malware is a name for any malicious software or file. Malware is specifically designed with the intent to steal, damage, or disrupt any kind of data or activity on a system. A Malware can be a file or fileless link, software, app, etc.
There are now several types of Malware, each with a different method of attacking a system.
Types of Common Malware
The following are some of the common types of malware.
It is one of the most common types of malware. A virus usually requires action from the user for activation. Viruses usually spread from one system to another system through email, messaging, web downloads, USB, and network connections.
As the name depicts, the keylogger logs a user’s keystrokes and sends data to the cybercriminal. They are very quiet and users are typically unaware that their system has a keylogger. They can steal passwords or sensitive data from a system. In addition to that, they are used against banks and big businesses.
A worm is quite similar to a virus. Just as virus, it can also self-replicate. A worm can be spread in full copies and segments through network connections, emails, and messages. An infected system can quickly spread worms over network connections.
Disguised as legitimate software, Trojan horse programs are another common type of malware. It hides in your system until it’s called upon. Trojans malware is indeed used to spy on you, steal your data, and can gain backdoor access to your system. It can spread through emails, web downloads, and messages.
Ransomware / Crypto-Malware
Specially designed to lock users out of their system or deny access to data. As the name suggests, it is designed with the intent to get a ransom for recovering access.
As blockchain is getting more common, there are high chances of facing Crypto-Malware. It is a sub-type of ransomware that encrypts user files and requires payment within a time frame. Furthermore, Bitcoin or other cryptocurrencies are the payment options as a ransom for such malware.
Only active when triggered, logic bombs is another common type of malware. Some viruses and worms often contain logic bombs to spread their payload at a set time or when a preset condition is met. To detect the most common types of logic bombs, some Antivirus software are available.
Adware & Spyware
Within a web browser, Adware is designed to serve advertisements on screens. When downloading a program, they get into the system in the background, without letting you know or your permission. They are, however, not that harmful as compared to viruses and worms but can be annoying for the user.
On the other hand, spyware is a type of malware that hackers are using to gain access and damage your computer. On the other hand, Spyware collects user’s information such as habits, browsing history, and personal identification information. It can spread from a software bundle or from file-sharing sites.
How Malware Can Be Deadly For Your Systems?
Getting malware on your system can be confusing. It can enter your system with any downloading of mp3, video, or any other software from unauthorized sites without your knowledge.
Meanwhile, to design and spread malware, hackers and cybercriminals are using modern tools and they can really infect your system.
An internet user can be a victim of different malware attacks. If malware, specifical spyware, enters your system, it can possibly steal your sensitive data or information. To a third party or to do identity theft sometimes, hackers are using that information.
A worm can be deadly for your system and once infected with a worm, it can slow down the performance of your system greatly and also can damage the system. And, it becomes very hard to find our viruses and worms as they run in the background unless you use a good antivirus or software removal. IT companies are the most affected by malware attacks so they need to equip effective security measures to protect their systems.
How Can You Protect Your System From Malware?
Malware attacks will continue to rise with the increased use of technology. It became very important to protect your system and your business from threat actors by using multiple layers of security. This method is called the “Layered Approach”.
The layered approach includes firewall, end-user training, patch and update management, anti-virus software, email, and web filtering software, network monitoring, and managed detection and response services, etc. It is important to use a layered approach as it ensures all the potential entry points for malware are protected.
First of all, there are many security practices that you can do and some are extremely important. However, keeping all your software up to date and removing software that you don’t use can protect your system from malware attacks. For example, most hackers send malware in the form of software updates. So make sure to update your software and system regularly.
It is worth noting that no system in the world is 100% secure and protected. In fact, hackers and cybercriminals always find a way to breach security. Nevertheless, the following are some of the best and equally important practices that you can do to make your system secure against major malware attacks.
- Evolving New Security Policies
- Performing Security Awareness Practices
- Always Using Multi-Factor Authentication For App-Based Softwares
- Installation of Best Anti-Virus and Spam Filters
- Implementing Regular Vulnerability Assessments
Summing Up For You!
Today, hackers and malware attackers have many different methods to spread malware in your system. Therefore, it’s extremely important to pay heed to the above-mentioned security practices otherwise your system will face damages and you will be going to lose many things.
