By employing cryptojacking, cryptominers, or coinminers, are able to mine for more transactions faster. However, the cryptojacked system will increase its power consumption, and the cryptomining activities will slow the device’s processing capabilities—sometimes causing the system to fail.

Cryptocurrency is a peer-to-peer system that allows anyone, anywhere in the world, to send and receive payments. In other words, it is a digital payment system that doesn’t rely on banks to verify transactions.

Once mined, blockchain technology keeps a record of the cryptocurrency to track when and where the currency is sent.

At the very least, it will also disable your antivirus and open up some of your secured ports in order to communicate with its command and control infrastructure.
