As the name “Ransomware” implies it is somewhere connected to ransom asked by the hacker or social engineer to the victim against the stolen data. Ransomware is a kind of malware that encodes your files and data. Then, the phishers/ hackers ask for the money or any payment to restore the access of the data from the victim.
The victims are provided with the instructions by following that they can pay a fee to avail of the decryption key. The ransom or the amount for the encrypted data completely depends on the confidentiality and the importance for any person or organization. The entire process is used to blackmail a person. This is one of the heinous crimes one can be trapped for.
Several instances show that victims often pay hundreds of dollars to lakhs to save their data which are stolen and encrypted.
How does ransomware work?

In the world of hacking, it is said that the mode of payment can happen to an untraceable Bitcoin account. Until the victim pays the hooping amount the files remain inaccessible and sending of these files to other systems can cause the crash and corruption in the chain. There are some of the types of ransomware which are infectious to the systems and can spread automatically across the internet in no time.
