Cryptojacking

Cryptojacking"" Cryptojacking occurs when a computer is used to mine cryptocurrency (such as Bitcoin) without the permission of the user. This type of attack uses the resources of the host machine to mine cryptocurrency without the users’ knowledge. It can cause a spike in energy costs and a significant decrease in the performance of a computer. Sophos research shows that cybercriminals are using the same cryptojacking tactics they use against businesses and employees as they do on consumers at home. This tells us just how opportunistic cybercriminals really are, and reminds us that security can’t stop when we leave the office.
