Cryptojacking is an advanced version of hacking in which computer’s processing power is hacked to mine cryptocurrency in the background without the knowledge of the system owner. In these cases, the hackers are not interested in the user’s data. For users, it is very difficult to know whether their system has been hacked or not as there are no visible changes in the system performance except sudden slow down of the system.
Hackers use cryptojacking technique to mine those cryptocurrencies which are ASIC resistant or can be mined using CPU’s power, unlike Bitcoin which uses ASIC for mining. In most cases of cryptojacking, Monero was found to be mined.
