Some days ago information about cryptocurrencies is circulating on the network, where we can find those that They argue that the end of them is yet to come, some others argue that they are in their prime and so on.
Something that has called my attention personally to this information and it is not something that is barely being talked about on the net is the following.
From a few months ago there have been some problems about cryptocurrency mining without the consent of the users.
Some of you already know what I am talking about, for those who do not know yet I will inform you a little. Well some time ago some of the most popular torrent web had within its source code a script with which it used your visitor's resources to mine cryptocurrencies.
This task It was done in a hidden way without the user noticing itIn a few days this was discovered by some of its users as they noticed that their computers were beginning to use resources in an absurd way by just using their browser.
This being the boom of a series of problems that have been arising, because more than one web master decided to do the same either in order to monitor their website or simply in order to abuse it and obtain profits at the expense of others.
With this a war has been started to make life easier without further complicationsBecause hackers are always in the lead.
Time passes and even solutions are obtained, such as by browsers blocking these scripts or by users implementing measures for this.
While On the Linux side, several distributions focused on mining have been presented of cryptocurrencies.
Offering as a solution for mining, I personally think in the future this type of distribution will be a target of hackers, to be able to get renumbered.
The hackers every day come up with a new method to continue mining cryptocurrencies using other people's equipment.
And what is the relationship of cryptocurrencies with graphics cards?
At this point is where the relationship begins, in the first instance for a few years cryptocurrency mining was quite profitable with the use of the best graphics cards.
With this factor involved, the manufacturers of these raised the cost of these in a huge way, because finding a graphics card with a value of more than $ 10,000 USD, for the simple fact that it can be used for mining is totally absurd .
When before this happened (just speaking randomly) the price of these was around $ 7500 or $ 8000 USD.
Today graphics card miner is simply not profitable anymore just by the simple difficulty of obtaining these it rises more and more.
In this way have started to see an improvement in graphics card costsWell, in the USA manufacturers started to lower costs and this will happen all over the world, we will see this in the course of this year.
But now a big problem also comes in through the back doorBecause hackers never stop making money at the expense of others.
Given that, now they seek to make a profit using the equipment of others in a rather peculiar way.
For a few months ago a way was detected in which many of them operate, in which infected computers use them to mine, this process can be done now without the need to have an open browser.
In this way they they are monetized in two ways:
1.- Using the equipment together as a botnet for the mining company and at the end of the work of each mined block, the hacker receives his reward directly to his wallet.
2.- The infected computers, the hacker makes them available to others. In short, it puts them up for rent so that others can use them as they please.
Though in Linux there is the belief that it is a system that does not have viruses, this is incorrect, because at least the top super computers as well as web servers use Linux and at least As far as the web is concerned, new vulnerabilities are discovered every day, so Linux is not 100 safe.
As a simple personal comment, I think that a great war is coming in a matter of obtaining cryptocurrencies at the expense of the use of external resources, so new and more sophisticated methods will be created.
