Crypto mining is no longer worthwhile for private individuals as the costs exceed the profits. But it’s still worth it for criminals because they simply use your resources! A disguised crypto miner mines the currency in the background, you only hear about it when you receive your electricity bill and the hackers cash in. COMPUTER BILD explains what exactly is behind it and how you can protect yourself.
Over time, the profits that can be made from mining decrease. One of the reasons for this is that lengthening the chain becomes more difficult with each new chain link. In addition, “halvings” take place regularly to counteract inflation. But they also ensure that the computing effort is doubled. In many cases it is therefore no longer profitable for private individuals to mine themselves: electricity and hardware simply cost too much.
Criminals have therefore come up with a trick: they mine with malware. These crypto miners often disguise themselves as games or simple programs and sometimes even offer corresponding functions. In the background, the crypto miner uses all of its computing power to mine cryptocurrency – of course for the benefit of the criminals. Anyone who has such a crypto miner on their PC is unintentionally making its computing power available to others, but is left with the electricity bill and hardware wear and tear.
Crypto miners are malware. Good antivirus programs (see above) detect and remove these like any other virus – or at best prevent the miner from getting onto the PC at all. Crypto miners get onto the hard drive via email attachments, infected websites or downloads. A protection program checks all of these avenues and only lets through what is not malware.
