Is it the latest buzzword in the world of malware or is it really worth the hype? You’re in good luck if you haven’t read much about this latest threat in the computing world. This is because we have summarized all you need to know about the threat itself and what you should do to safeguard your interests.

The growing implications and the hype around ransomware lead us all to one question in general— what is ransomware? By definition, ransomware is a complicated malware that blocks the victim’s access to all the files that they had previously stored in their system. After the attack takes place, the said victim has no access to their files anymore. In addition, the only plausible way left for them to get their priceless data back is by paying a specified amount of money to the attacking party.

This malware has spread like wildfire, and it is a common tool for hackers to manipulate users and organizations into paying money. A malware containing ransomware could be unfolding anywhere across the world right now—near you, in your neighborhood, your office building and what not. Someone might be clicking open a link that contains a malicious email without being aware of what consequences it can have. Once they do, they will immediately be contacted by the hackers through a message displayed on their screen. This will be asking for money—usually in the form of cryptocurrencies.

Types and Attributes of Ransomware

Ransomware is usually grouped into two distinctive types. These types are self-explanatory and form the basis of almost all ransomware attacks.


Such a type locks the user files, making it impossible to access data. The victims of such ransomware attacks are unable to access their files because the files are locked away and can’t be seen.


These ransomware attacks tend to encrypt all the data and files present on your system. They achieve this encryption through the use of advanced encryption algorithms and methods. Once the files are encrypted, they are almost inaccessible. The key for decryption will only be provided if you pay the specified amount asked for by the attackers.

Besides these two distinctive types, ransomware also carries several distinctive attributes. These attributes make them different from other malware tools. Understanding these attributes will further help in the categorization of ransomware as different from other malware.

Ransomware comes with the ability to encrypt almost all kinds of files online. This gives these attacks an edge that other malware does not possess. Due to its unique attacking method, ransomware can encrypt almost all kinds of files within your computer in one go. This includes videos, audios, pictures, and all other formats. Their ability to encrypt such a variety of files and formats makes ransomware even more threatening and dangerous than other malware.

The encryption is often too hard for you to break on your own. No matter how hard you try, you will either require expert help or a ransomware removal software to generate an idea of what is going on.

Once your system(s) gets attacked by a ransomware attack, your screen will display a message or an image on it. The message will notify you of the attack, and the money you’d be required to pay for the proper restoration of all data.

All computers connected to the same local network are susceptible to a ransomware attack, even if one of them gets the malware. Ransomware spreads like fire in computers connected to the same local network and locks data across all these systems.

More often than not, there is a time limit on the on-screen notification. The time limit is meant to threaten you and spur you into action. If the money isn’t paid within the time limit, attackers either increase the ransom amount or scrape off the data that is encrypted.

How to Prevent a Ransomware Attack?
