How does ransomware work?

Ransomware is a type of malware that encrypts a victim’s files and demands a ransom in exchange for the decryption key. The key is typically unique to each victim, making it impossible to decrypt the files without paying the ransom. Ransomware is typically spread through phishing emails or by infecting websites with malicious code. Once a victim’s computer is infected, the ransomware will start encrypting files and display a ransom note with instructions on how to pay the ransom. Ransomware is a growing threat because it is relatively easy to deploy and can be very profitable for attackers.

Most ransomware attacks follow a similar pattern:

A victim receives a phishing email or visits a website that has been infected with malicious code.

The email might contain a malicious attachment or link that, when opened, downloads and executes the ransomware on the victim’s computer.

Once executed, the ransomware will start encrypting the victim’s files using a strong encryption algorithm. The encryption key is unique to each victim and is typically stored on a remote server controlled by the attacker.

Once the files have been encrypted, the ransomware will display a ransom note with instructions on how to pay the ransom. The ransom is typically demanded in Bitcoins or another cryptocurrency.

If the victim pays the ransom, the attacker will send them the encryption key that can be used to decrypt the files. However, there is no guarantee that the attacker will actually provide the key and it is not uncommon for victims to not get their files back even after paying the ransom.

Ransomware is a growing threat because it is relatively easy to deploy and can be very profitable for attackers. In 2019, there were over 4,000 ransomware attacks per day, with attackers demanding an average ransom of $84,000. The amount of ransom demanded has been increasing over the years as attackers become more sophisticated and better at deploying ransomware.

There are several steps that you can take to protect yourself from ransomware:

Keep your software up to date: Install security updates for your operating system and other software as soon as they are available.

Install anti-malware software: Anti-malware software can detect and remove ransomware before it encrypts your files.

Back up your data: Regularly back up your data to an external hard drive or cloud storage service. This will allow you to restore your files if you are infected with ransomware.

Be careful when opening emails and visiting websites: Do not open email attachments from unknown senders and be careful when clicking on links in emails or visiting websites.

How can ransomware be prevented?

There are a few things that can be done in order to prevent ransomware:

1. Keep your software up to date: One of the most important things you can do to protect your computer from ransomware is to keep your software up to date. Software updates often include security patches that can help protect your computer from the latest threats.

2. Use a reputable antivirus program: A good antivirus program can detect and block many types of malware, including ransomware. It’s important to keep your antivirus program up to date, as new ransomware variants are constantly being released.

3. Don’t open email attachments from unknown senders: One of the most common ways that ransomware is spread is through email attachments. If you receive an email from an unknown sender, do not open any attachments.

4. Be cautious when downloading files from the internet: Another common way that ransomware is spread is through malicious files that are downloaded from the internet. Before downloading any files from the internet, make sure that you trust the source.

5. Back up your files: One of the best ways to protect your files from ransomware is to back them up regularly. This way, if your computer is infected with ransomware, you can restore your files from the backup.

Following these simple tips can help protect your computer from ransomware.
