Ransomware is a type of cyber attack, which take control over a computer and prevents the user to access data until ransom is paid. The attacker encrypts the data and stops other software and apps from running. Such malware is causing millions of dollars financial loss [1]. Users are given instructions for how to pay ransom to get the decryption key. The costs can range a few hundred dollars to thousand payable to cybercriminals in Bitcoin. Cryptojacking is emerging as a more cost-effective and efficient alternative to ransomware, in ransomware attack there is no guarantee that the attacker will get ransom. On the other hand Cryptojacking empowers hackers to make use of infected computers and assures financial gain. Cryptojacking is the illegal practice of accessing and using the resources of a target computer, mobile device, or server to mine cryptocurrencies [2].
