An anonymous reader writes: According to a report released yesterday, criminal groups have mined an approximate total of 798,613.33 Monero coins (XMR) using malware on infected devices. That's over $108 million in US currency, just from coin-mining operations alone. This sum also represents around 5% of all the Monero currently in circulation -- 15,962,350 XMR. Furthermore, during the past year, infected devices were responsible for 19,503,823.54 hashes/second, which is roughly 2% of the entire hashing power of the Monero network. The total hashrate of roughly 19MH/s would result in approximately $30,443 per day based on today's current exchange rates and network difficulty," researchers said. "Similarly, the top three hash-rates will mine approximately $2,737, $2,022 and $1,596 per day, respectively."
