What Is Ransomware and How Can It Be Prevented?

Cloudmatika / March 23, 2026

The global COVID-19 pandemic has led many companies to implement work-from-home policies, resulting in increased use of technology while working. While this increased use of technology makes it much easier for employees to work as if they were in the office, cybersecurity attacks—such as malware, ransomware, and others—are inevitable.

What Is Ransomware? One of the most dangerous cybersecurity threats is “ransomware.” A ransomware attack involves a virus that encrypts files on a PC, rendering the data unreadable to the owner.

Ransomware attackers typically extort victims, often targeting companies with these attacks. They demand a ransom from the victim. If the victim pays the ransom, the attackers will decrypt the files and restore them to their original state.

Currently, there are many types of ransomware, one of which is WannaCry, which emerged around 2017. In 2020, a new type of ransomware called MAZE emerged and became a global epidemic.

Challenges in Ransomware Prevention

There are several challenges in preventing ransomware in today’s world

One issue with ransomware prevention is that attackers have become so sophisticated that it is difficult to prevent ransomware infections, and once infected, the likelihood of regaining access to the data is low.

Ransomware is currently the most popular method “chosen” by attackers, and its techniques and methods are evolving daily. Although the primary transmission route is through links and attachments in spam emails, it is often difficult to prevent attacks because the emails appear completely normal—for example, identical to emails from trusted business partners.

Furthermore, once infected with ransomware, it is extremely difficult to recover files that have been encrypted. Even if you pay the “ransom” demanded by the attackers, there is no guarantee that your data will be restored.

Unfortunately, there have been many cases resulting from ransomware attacks where the ransom was paid in full, yet the encryption was not reversed. Ultimately, victims have no choice but to accept the loss of their data.
