The attacker then demands a ransom from the victim to regain access to the data upon payment in a virtual currency such as Bitcoin.

You are presented with instructions on how to pay a fee to obtain the decryption key. Costs can range from a few hundred dollars to thousands, and you pay cybercriminals in Bitcoin.


What are the types of ransomware?

Depending on the result of the attack, ransomware can be classified into the following categories:

Locker Ransomware: ransomware that shuts down your system and demands a ransom is classified to give you access to locker ransomware.

Crypto-Ransomware: This type of ransomware encrypts your files and forces you to pay a specified amount of money to decrypt your files.

The victim is required to pay for the anti-virus program that removes this virus.

Ransomware Android Mobile Device: This type of ransomware either permanently close your mobile phone or steals its sensitive data, and requires a ransom to unlock it or to return the data.

IoT Ransomware: This category of ransomware is designed to gain access to your IoT device, and at the same time, it prevents you from accessing your device.



What are the forms of ransomware virus?

Ransomware dates back to 1989. The worst thing about being infected with ransomware is that it doesn't show any symptoms early enough to prevent disaster from occurring. Moreover, with the advancement of technology and the introduction of Bitcoin - an anonymous payment method - it became easier for attackers to flee because these digital transactions could not be tracked. As a result of this, cybercriminals, as well as various forms of ransomware, are increasing in the internet world.


How does ransomware work?

Several ransomware antivirus programs can take to gain access to a computer. One of the most common delivery systems is unwanted spam - attachments that come to the victim in an email, masquerading as a file that you should trust. Some of the other, more aggressive forms of ransomware, like NotPetya, exploit vulnerabilities to infect computers without having to trick users.


How does the ransomware take control of your system?

- Ransomware can enter your system by browsing untrusted websites

- It can spread into your system by opening or downloading email attachments from an untrusted source

- Installing programs, games, etc. from untrusted sources may result It also means that your computer is infected with the ransomware virus

- the ransomware can reach your system if it is connected to a network that has other machines infected with this virus.


What are the symptoms of a ransomware attack on your computer?

- You are unable to open files on your device

- Disturbing messages appear on your desktop

- You find programs creating a warning message via the countdown

- A popup window appears indicating instructions on how to pay to unlock your files

- Receive errors related to corrupt data, wrong file extensions, etc.

- A message displayed on the screen asking for a ransom and cannot be closed

- Some of the file extensions have been changed or lost.


How to prevent ransomware from reaching your device?

There are several defensive steps you can take to prevent getting infected with ransomware. Of course, these steps are generally good security practices, so following them improves your defenses against all kinds of attacks:

- Keep your operating system up-to-date to make sure you have fewer vulnerabilities to exploit.

Do not install programs or give them administrative privileges unless you know exactly what it is and what it does.

 Install total security, antivirus software, which detects malware like ransomware when it arrives, and that prevents unauthorized applications from running and installing in the first place.

- Back up files frequently and automatically! This won't stop the ransomware attack, but it can lead to fewer losses.


How to respond to a ransomware virus if you catch it?

1- Immediately disconnect from any network and the Internet. Disconnecting the connection in this way isolates your computer and reduces the chances of the ransomware spreading to other computers.

2- Do not pay any ransom demanded by the cybercriminals who carry out the ransom attack, as, like the hostage situation in real life, it is better not to negotiate with the cybercriminals. Paying the ransom won't guarantee your data being returned - all these individuals have already tampered with your trust. Where yielding to push encourages this type of crime. The more people pay the ransom, the more popular ransomware attacks become.


How to remove ransomware from your device?

If your computer has been infected with ransomware, you will need to take back control of your device.

- Disconnect from the Internet

- Restart Windows to Safe Mode

- Install anti-malware program especially anti-ransomware like Malwarebytes

- Perform a full and in-depth scan of your system to find Ransomware

- Restore files from Backup Restore previous versions

- Programs Recover deleted files will also help you recover files that have been encrypted or damaged by the ransomware virus.

But this is the important thing to consider: As you go through these steps, you can remove the ransomware from your computer and regain control of it because these steps will not be able to decrypt your files. Unfortunately, it has already been turned into unreadable files, and if the ransomware is so powerful and intelligent, it would be mathematically impossible for anyone to decrypt it without accessing the key the attacker carried. In fact, by removing malware, rule out the possibility of your files being restored by the attackers paying the ransom they requested.

As we said, the necessary solutions to recover your important files are either by restoring the system to a previous state, and this tool is integrated with Windows, or by using programs to restore the removed files.
