If your computer is being used for cryptojacking, the only sign you might notice is slower performance or lag in execution.

In most cryptojacking cases that got reported, neither the owners of the compromised website nor its users were aware that they were the victims.
 5. What type of websites are usually targeted for cryptojacking?
Attackers mostly target unprotected websites that receive massive traffic (has a lot of visitors) on a daily basis and compromise them with crypto mining codes. These websites could include government or news portals and even those that provide some kind of online service. And when individual users access these compromised websites, the crypto mining code hijacks their web browsers and begins the mining activity.

Cryptojacking consumes your computer’s processing power and slows down the system to an extent where you might not be able to carry out any task. This can significantly impact you if you are a working professional, tester, gamer, etc. Furthermore, if your computer is mining cryptocurrency, it will unnecessarily increase your electricity bill.
In some cases, cryptojacking has also been reported to crash the infected computer and even cause physical harm to Android devices by overheating their batteries.
