A water utility provider in Europe is literally being drained of its CPU power via an cryptojacking attack that was undetected for three weeks. eWeek reports: "At this point, Radiflow's (the security firm that discovered the cryptocurrency mining malware) investigation indicates that the cryptocurrency mining malware was likely downloaded from a malicious advertising site. As such, the theory that Radiflow CTO Yehonatan Kfir has is that an operator at the water utility was able to open a web browser and clicked on an advertising link that led the mining code being installed on the system. The actual system that first got infected is what is known as a Human Machine Interface (HMI) to the SCADA network and it was running the Microsoft Windows XP operating system. Radiflow's CEO, Ilan Barda, noted that many SCADA environments still have Windows XP systems deployed as operators tend to be very slow to update their operating systems." Radiflow doesn't know how much Monero (XMR) cryptocurrency was mined by the malware, but a recent report from Cisco's Talos research group revealed that some of the top un-authorized cryptocurrency campaigns generate over a million dollars per year. The average system would generate nearly $200,000 per year.
