Talk about throwing a wrench into your work day.

Factories around the world rely on Wi-Fi-enabled wrenches to precisely calibrate the torque applied to screws and other fasteners. Now, Ars Technica points out that those tools are hackable.

Researchers from Nozomi found 23 vulnerabilities in the operating system of a popular connected tool, which could be exploited to install malware. In theory, at least, this could lead to fastening screws too tightly or loosely, disabling an entire fleet of wrenches, and otherwise disrupting the factory’s operations.
