   Cryptojacking has transformed into a famous route for criminals and bad actors to extract money in the form of cryptocurrency. Cryptojacking is a sort of cyber attack in which a programmer illegally seize a target's computational power with a goal to mine cryptocurrency for the programmer’s benefit. Cryptojacking adopts an alternative strategy, misusing the victim's devices to mine, making new tokens and creating fee and charges at the same time. These new tokens and fees are kept to wallets owned by the hacker, while the expenses of mining – power, wear and tear due to the overuse of computer etc. – are borne by the victim.


HOW IS CRYPTOJACKING DONE?

    Cryptojacking is an illegal use of another person's computer to mine cryptocurrency. Cryptojacking does not require any program to be installed for crypto mining. Hackers use JavaScript code to mine cryptocurrencies in light of the fact that JavaScript is the world’s most ubiquitous computing runtime also you don't have to download much else besides the website pages with JavaScript. It keeps running on each site you visit. You continue loading the pages and the mining code keeps running along. Cryptojacking code doesn't make any harm to the victim's data. Everything it does is stealing the CPU processing power for mining the cryptocurrencies. The victim witness with either the slower performance or delay in execution. This makes the victim clueless about the procedure occurring out of sight. Cryptojacking is becoming popular because it doesn’t require specialized skill, it is less expensive and more productive for a hacker. The crypto mining code runs secretly and the source cannot be easily traced


    Zcash and Monero happen to be few forms of cryptocurrencies that permit mining with CPU as they are privacy-focused, anonymous and difficult to track the illegal movement.
