Understanding and Protecting Against Ransomware

Ransomware is malicious software that blocks access to a computer system until money is paid. It is a form of cyberattack which is becoming increasingly common. The following explains what ransomware is, how it works and how people can protect against it.

What Is Ransomware?

Ransomware is a type of malicious software that is designed to deny access to a computer system or its files until a ransom is paid. It can be spread through malicious email attachments, downloads, or open networks. Once it has been installed, the ransomware will usually encrypt files, videos, images and documents.

How Does Ransomware Work?

Ransomware usually begins with a user receiving an email containing a malicious link or file. Once the user clicks on the link or downloads the file, the ransomware is installed on their computer. The ransomware will then start to encrypt files, or lock the user out of their computer completely, blocking access to their data. The cybercriminals behind the attack will then demand a ransom, usually in Bitcoin or other cryptocurrency, in exchange for releasing the locked files.

How Can You Protect Against Ransomware?

Protecting against ransomware attacks is possible if people take the necessary steps:

• Be cautious when opening emails and attachments - Emails from unknown senders should be avoided and attachments should not be opened unless they are from a trusted source.
• Back up your files regularly - Regular backups will ensure that you are able to restore your files in the event of a ransomware attack. These backups should be stored on a separate device, preferably offline.
• Keep your operating system and other software up to date - Outdated software is more vulnerable to attack, so it is important to ensure that your operating system, web browser and other software is kept up to date.
• Install antivirus software - Antivirus software can help to detect and remove ransomware before it takes hold.

Ransomware is becoming an increasingly common form of cyberattack, but understanding how it works and taking the necessary steps to protect against it can help to make people and companies less vulnerable.
