Just days after the WannaCry cyberattack hit computers around the globe, a new virus is spreading. It exploits a Windows bug that Microsoft (MSFT) issued a patch for in March, but countless devices around the world remain vulnerable.

The latest malware, dubbed Adylkuzz, doesn’t steal data and hold it ransom, but rather secretly steals processing power to generate a digital currency known as Monero, reported  the Wall Street Journal. "While the amount of money generated from each individual machine infected is small, done on a large enough scale, it would still generate a significant amount of untraceable money for the perpetrators," said antivirus provider Bitdefender in a statement reported on by Wired.

Adylkuzz has reportedly been spreading for around two weeks and as of Wednesday hit more than 150,000 machines, which WSJ noted is close to the number of systems that were impacted by WannaCry. 

At the same time, the cyber hacking group known as Shadow Brokers is threatening to release more hacking tools in June that could hurt web browsers, routers, smartphones and the Windows 10 operating system. (See also: Microsoft Word Target of Zero-Day Malware Attack.)

In a statement to the Wall Street Journal, a spokeswoman at Microsoft said it is aware of the Shadow Brokers latest antics and that the security team within the company is on the watch for new threats or attacks. The firm, which has been criticized in the wake of WannaCry for abandoning customers running older versions of its Windows operating system, is also seen benefiting from the virus outbreaks. In a research note to clients Credit Suisse argued that the fast spreading attack should prompt more users to upgrade to Windows 10. "The recent global ransomware attack exploiting a flaw in Windows, while serious, not only demonstrates the continued ubiquity of Microsoft, but also highlights that many of the affected enterprises or entities that are still using older, and now unsupported, versions of Windows need to accelerate their plans to upgrade to Windows 10," analyst Michael Nemeroff wrote in a recent note to clients. "If you're not current, you're toast."  (See also: Microsoft Blames Users, Spy Agencies As It Faces Rising Criticism)   

The severity of the WannaCry attack and concerns that more are coming has prompted Wall Street and investors to speculate that increased corporate dollars will go to secure computer systems which will be a boon to cybersecurity stocks and even Microsoft. Earlier in the week shares of a handful of stocks that make software to protect servers and computers gained, including Symantec Corp. (SYMC)  Sophos Group (SOPH.L), Palo Alto Networks Inc. (PANW), FireEye Inc. (FEYE) and CyberArk Software (CYBR).
