A computer security exploit developed by the US National Security Agency and leaked by hackers last year is now being used to mine cryptocurrency, and according to cybersecurity experts the number of infections is rising.

Last April, a hacking group called the Shadow Brokers leaked EternalBlue, a Windows exploit that was developed by the NSA. Less than a month later, EternalBlue was used to unleash a devastating global ransomware attack called WannaCry that infected more than 230,000 computers in 150 countries. A month later, in June, the EternalBlue exploit was again used to cripple networks across the world in an even more sophisticated attack. Now, security researchers are seeing the EternalBlue exploit being used to hijack people’s computers to mine cryptocurrency.
