Definition of Cryptojacking
What is Cryptojacking?
You may not have known it, but some sites mine cryptocurrencies without your knowledge with your computer while you consult them! This is called cryptojacking! This is not a joke. There are short scripts that, in less than 10 seconds, can be integrated into a website’s source code and that allow the webmaster to mine cryptocurrencies through your machine. These scripts run without your knowledge on your browser, and exploit your computer’s performance!
Cryptojacking in action!
Here is the system set up to perform cryptojacking:
The webmaster simply has to register on the coinhive site, then generate a short script to integrate it onto his website, install it in the code of all his site’s pages, then visitors are cryptojacked without knowing it. And he gets free mined cryptocurrencies using your machine.
Visitors who are cryptojacked do not necessarily realize it, but their machine is taking a hit!
- high processor (CPU) utilization
- reduced battery life
- increase in the machine’s energy consumption
as well as material wear and tear, consulting the site is even more expensive for the web user.
Is cryptojacking allowed?
There is no official answer to this question, but it seems obvious that this is not honest!
The general regulations for protection of data relating to cryptojacking are very good but there are still measures which lag behind!
