IBM says it has seen a decline in so-called browser-based cryptojacking attacks. Those attacks – known as cryptomining – use victim’s computers to generate random hashes as part of the proof-of-work transaction systems for virtual currencies in return for a reward payment. The value of virtual currencies such as bitcoin and monero has fallen 75 percent or more since December 2017, when bitcoin peaked at around $20,000 per coin, it and other cryptocurrencies has fallen more than 75 percent. IBM is predicting that the move to malware-based mining will evolve.”]
