Cryptojacking might sound like an exciting term in the crypto space but trust me it’s something you will always want to prevent from happening to you. Cyber crimes are continuously evolving and becoming more complex and creative in a variety of fields. Crypto space is no different. It is, therefore, not a wonder that users have reported and are concerned whenever their cryptos are hijacked or compromised. This act is referred to as crypto-jacking, and in most cases, the user is usually unaware. So, what exactly does this act involve, and how can you detect, prevent and recover from it?
What is Crypto Jacking?
This is the act of hijacking a computer system and having it mine crypto coins without the knowledge or will of the user. The unauthorized criminal utilizes the user’s computer, tablet, smartphone, or any other device or server, and uses the resources within to mine the cryptocurrency. He can introduce cryptojacking software in the device or server which will in turn aid in mining the crypto. Additionally, the hackers conduct it in a way that keeps the victim totally in the dark, unaware of what is happening in their crypto.
Remember, the goal of such criminals is to get the profits of crypto mining without undergoing the hassle or being responsible for paying the hardware used, the fees charged, or the electricity bill. As a user, you need to protect yourself against this type of threat especially since most cryptocurrency buying and selling sites are virtual. However, how about detecting them first?

How Do You Detect Crypto Jacking?
As a user who has incurred the huge costs of mining crypto, you wouldn’t want a second party to reap the profits. Unfortunately, detecting cryptojacking can be a hassle. This is because you will typically not experience the actions taking place in your system. The following are some of the things you can look out for to detect cryptojacking;
- Your Device Performing Slower Than Usual
If you have been using the same computing device or server to mine cryptocurrency for a while, no doubt you know its performance level.

Chances are that a cryptojacker may have already installed hacking software on your device.
- Overheating of Your Computing Device
If you notice that your computing system overheats more than normal, it could be a sign that a hacker is mining your crypto.

As a user, you probably know the battery performance of your computer or device. Therefore, if there are changes and it begins performing poorly, it could be a symptom that a hacker is trying to reap the profits of your crypto mining.
