Today we are going to talk to those of you who use Bitcoin digital currency to pay for a variety of goods and services – along with a warning about yet another source of Bitcoin miners – the sharing services. You may think that if you avoid cracks and keygens while browsing the web you will be safe. Well, we would recommend that you reconsider that position. Recently we found that on the uloz.to file sharing service someone uploaded a lot of fake files containing Bitcoin miners!
Bitcoin Mining service
First a little background for the uninitiated: Bitcoins can be obtained by trading real currency, goods, or services with people who have them or alternatively, through mining. The mining process involves running software that performs complex math problems for which you’re rewarded a share of the income. There are a finite amount of Bitcoins to be had, and mining for them can be compared to extracting gold or diamonds from the earth. The more you get, the fewer there are to be had, so it becomes increasingly harder and more expensive. Here’s a descriptive article about mining.
Bitcoin mining services such as bitminter.com use shared computer resources of their users to mine new Bitcoins. In order to participate, the mining users have to create an account and then register their computers (workers) with the service. Then they simply run the Bitcoin miner program provided with their credentials on as many computers as they have. In the end, if they had enough computation power and time they might end up with a few Bitcoins.
