The Dangers of Ransomware Attacks and How to Prevent Them

Ransomware is a type of malware that prevents victims from accessing their data by encrypting specific files or even entire computer systems and then demanding a ransom, usually in the form of a cryptocurrency, such as Bitcoin, to decrypt it.

How Ransomware Works

After successfully infecting the system, the ransomware will immediately encrypt the data. A message will appear on the victim’s screen explaining that their data has been encrypted and will provide instructions on how to pay the ransom to obtain the decryption key.

Danger of Ransomware Attacks

Behind the ransom demand, there is a much more significant impact that can affect a company or individual. This attack not only involves financial losses but also other long-term impacts.

Types of Ransomware and How to Recognize Them

Ransomware has become one of the most disturbing cyber threats for technology users today. As a type of malware, ransomware can hijack and lock user data, demanding ransom so that the data can be reassessed. To understand more deeply, here are several types of ransomware that you need to know:

1.Screen Lockers

Screen Lockers, as the name suggests, work by locking the home screen of the infected device. When a device is infected, the screen will display a message or image that covers the entire screen so that the user cannot access anything on the device.

2.Web Server Encrypting Ransomware 

This type of ransomware attacks web servers, especially those that have a CMS (Content Management System) with low security. This attack focuses on encrypting the essential data of a website, thereby causing damage to files and stopping access to the site.

3.Master Boot Record (MBR)

This attack is more in-depth because it targets the Master Boot Record of the computer’s hard drive. By encrypting the MBR, the computer cannot boot because the process is interrupted.

4.Encrypting Ransomware 

This type is the most common type of ransomware. Encrypting ransomware will encrypt essential files on the victim’s device, ranging from documents, photos, and videos to various other essential data.

5.Ransomware for Mobile Devices

As the name suggests, this type of ransomware attacks explicitly on mobile devices such as Android smartphones. Typically, infections occur because users access unsafe websites or download applications from unofficial sources.

Impact of Ransomware Attacks

Financial Loss

Apart from having to pay the ransom, victims may also experience other losses, such as data recovery costs, security consultation fees, and others.

Reputational Damage

Reputational damage can impact the trust of customers and business partners, who may be hesitant to do business again in the future.

Data Loss

Even if the ransom is paid, there is no guarantee that the data will be returned. Some victims even still lose their data after paying.

Operational Disruption

In the case of companies, business operations can be disrupted for days or even weeks while IT teams work to restore systems.

How to Prevent Ransomware Attacks

Adequate Cybersecurity Implementation

Make sure your antivirus and firewall software are continuously updated. Also, use more specific security solutions to prevent ransomware.

Educate Employees About Cybersecurity

Employees should be educated on how to identify phishing emails and the importance of not clicking on suspicious links or downloading suspicious attachments.

Perform regular data backups

Do data Backup regularly and store it in a safe place. In the event of an attack, you still have a recoverable copy of your data.


In today’s digital era, ransomware has become one of the most disturbing cyber threats. The impact of this attack is not only limited to financial losses but also reputational damage, loss of essential data, and operational disruptions that can hamper productivity. Facing this reality, individuals and companies must increase cyber awareness and protection. Preventive steps such as employee education, data backup, and implementing adequate cybersecurity are the primary keys to avoiding the negative impacts of ransomware attacks. In the midst of increasing threats, preparedness and prevention are our best weapons.

Make sure to always be careful when surfing the internet, downloading applications, and opening emails from unknown sources. Always protect your devices with reliable security solutions like those offered by Vidia Cloud.
