There is a new malware in town to rival ransomware and this time it is linked to the explosion in crypto-currencies such as Bitcoin. Crypto-currencies are based on transaction verification and so-called crypto-mining provides 24/7 accounting for these currencies, for which it receives a small fee.
Anyone can engage in this activity, but to make real money from crypto-mining requires vast amounts of processing power. Some miners now appear to have started to tap into other people’s networks to borrow their processing capacity in order to do this. A bit like cannabis farms tapping into the next door neighbour’s electricity supply to keep their plants warm.
