A security researcher has just discovered a stealthy cryptocurrency-mining malware that was also using Windows SMB vulnerability at least two weeks before the outbreak of WannaCry ransomware attacks.

One Monero is currently valued at around US$26.77, and one Bitcoin-like cryptocurrency is valued at about US$25.77.
