Cryptojacking is using someone else PC’s memory and processor power for mining and generates money out of it. It has emerged as a shortcoming of the rising popularity of bitcoin.

Creation of new units of cryptocurrencies involves complex mathematical calculations for attaining secured transactions. It also offers an objective record of the orders in which the transactions are performed. A user who successfully performs these calculations is rewarded with a small amount of that cryptocurrency. Over the time, enterprising cryptocurrency enthusiasts created a way to earn profit out of other’s processing and electrical powers.

There are two types of Cryptojacking:

  1. It tricks a user into downloading a mining application into their PC. It is an easy way to attract people to certain website page and embed a mining script into their PC.
  2. Another way is to insert cryptomining scripts into ad networks that legitimate websites then indirectly serve to their visitors.

The mining script can be just some lines of text that download a small program from a web server, start itself on an individual’s browser and state the program to where to credit any mined cryptocurrency. The user’s computer and electricity will be the host whereas the person who coded the cryptocurrency gets all the profits without taking it to the user’s knowledge.

What are the damages caused by Cryptojacking?

Mining is a very processor-intensive procedure, extracts more power. So, while processing mining, the laptop’s battery will drain faster.

Likewise, a desktop computer will extract more power to provide power to the processor and to run fans to avoid overheating of the machine. And even if the system is properly cooling, the elevated temperature may cause problems in long-term, harming hardware and slowing down the speed of the computer.

This affects not only an individual’s system whose computer has been hijacked for cryptocurrency mining but also institutions, companies, and other large organizations. A large number of cryptojacked systems of an institution can eat-up a considerable amount of electricity and harm large numbers of computers.

How to prevent Cryptojacking?

Cryptojacking may be recognized by the user on his own as it involves heating up of the system, increased processor activity. The computer fan may start or run more quickly to cool the system.

If a person finds out or doubts whether his/her computer has been cryptojacked, it is advisable to run an antivirus program. It will not only identify the cryptojacking scripts but also check for other types of malicious software. This includes recognizing and obstructing mining malware and even browser-based mining scripts.

Installing antivirus software updates may also aid users to block the interface that attempts to download cryptojacking software or other harmful programs to their systems. Additionally, browser add-ons that block mining scripts can decrease the possibility of being cryptojacked by code embedded in the websites.

Surely, cryptocurrency mining can be a legit source of income; but there should not be any attempt to secretly hijacking others’ computers to do the beneficiary’s work and having them pay the subsequent financial costs.
