How To Decrypt Ransomware

The ransomware virus is a common type of computer virus that has been there for many years. It comprises numerous variations. Famous ransomware viruses are MRCR, Merry Christmas, Umbrecrypt, Hydracrypt, Cryptolocker, GandCrab, and Teslacrypt.

A lot of ransomware viruses can now be decrypted with a specific decryption program. Security developers are continually coming up with new decryption techniques. Myspybot.com offers a list of currently available decryption tools

On their turn, the ransomware creators are also always evolving. For this reason, it is difficult for an average computer user to know how to fight back if their files get encrypted with this malicious virus. Fortunately, there are som methods anyone can use to decrypt files infected by the ransomware virus.

How Ransomware Encrypts Files

Encryption can be defined as the process of encoding data in a way that makes it only accessible to authorized parties. The ransomware virus encrypts computer files with a key that is only known to the cyber crook who sent the virus. Once the infection is deployed, it runs a set of processes on the infected computer creating encrypted copies of original files.

The virus then deletes the original files leaving the copy file appearing as though it is corrupt. Once the encryption process completes, the virus will generate a decryption key, which is always private and know only to the attacker.

Once a ransomware virus encrypts your files, the user cannot access the data or the system. The main goal of the ransomware developers is to demand a ransom from infected users for getting back a decryption key. In the 1980s, ransoms were required to be paid using snail mail. Today, payment is demanded using cryptocurrencies like Bitcoin or a very private one called Monero.

How Does One Get Infected With Ransomware?

Malicious spam email messages are the most common method used by hackers to deliver the virus. The virus is encoded in an attachment, such as a PDF file or a Word document. Weblinks are also used to redirect the user to a malicious site. Malspam makes use of social-engineering methods to lure unsuspecting victims into clicking on the links or downloading the attachments.

Online scammers can impersonate the FBI or a security unit to scare the recipient into paying a large sum of money as ransom. They can also pretend to be a bank worker or even your boss. The good news is, you do not always have to pay the ransom to cybercriminals. There are steps you can follow trying to recover your files.
