A number of apps in Microsoft’s app store have been found to be able to illicitly mine cryptocurrency.
The eight apps, discovered by Symantec on Jan. 17, hosted a version of Coinhive, a script for mining the monero cryptocurrency that has proved popular with cyber criminals.
In a blog post on the discovery, Symantec said it had reported the apps to Microsoft, which subsequently took them down. The apps all ran on Windows 10, including Windows 10 S Mode, which restricts app downloads to the Microsoft Store.
Three developers, DigiDream, 1clean and Findoo, reportedly produced all the apps, which covered the areas of computer and battery optimization tutorials, web search, web browsing, and video viewing and download.
Symantec wrote in the post:
“In total, we discovered eight apps from these developers that shared the same risky behavior. After further investigation, we believe that all these apps were likely developed by the same person or group.”
