The Cyber Threat Alliance claims that a software tool leaked from the NSA is fueling a massive rise in cryptocurrency mining malware. The cyber-security experts claim they detected a "459 percent increase in the past year of illicit crypto mining," and point to leaked NSA software called "EternalBlue" as a major contributing factor. Even though patches for this malware were released over a year ago, organizations across the world are still being victimized, the researchers say. Most of the malware mines Monero, which is extremely difficult for investigators to track. "Illicit mining is the 'canary in the coal mine' of cybersecurity threats," he said. "If illicit cryptocurrency mining is taking place on your network, then you most likely have worse problems and we should consider the future of illicit mining as a strategic threat."
