What is ransomware?

Ransomware is malicious software that encrypts the victim's files then asks him/her to pay for the decryption key, the affected files are usually media (images, video, ...), documents and database files. The ransom is paid in digital currency, such as BitCoin, because it can not be traced.

The virus usually spreads in the form of Trojan via email as an attached file that affects the victim's computer when he/she executes the file, but this is not always the case where the famous ransomware known as WannaCry spreads via an exploit without user intervention.

GandCrab ransomware virus

The damage caused by GrandCrab is estimated at hundreds of millions of dollars according to the statement made by the BitDefender team. At the time of writing, there are 5 versions of the virus which indicate an active team behind the virus. According to the statement, with the release of this version of the tool, it is expected that a new version of the virus will emerge soon.

BitDefender was and still is at the forefront of the war against ransomware viruses and in particular GandCrap, they released the first version of the decryptor with the first version of GandCrap (v1.0 and v1.1). The first decryptor helped more than 2,000 individuals, users, businesses and non-profit organizations recover their files without ransom.

In the same week, the first decryptor was released, the criminals behind GandCrab released a second version of the GandCrab 2.0 virus. It started the game of cat and mouse between Bitdefender and GandCrab up to version 5.1 at the time of writing.

BitDefender estimated that a total of 20,000 people and organizations recovered their files using the decryptor, saving $ 18 million, which had to be paid in ransom.
