Some developers are using the small print to turn their desktop computer apps into programs for creating crypto currency. Security software firm Malwarebytes has discovered at least one application — a free Wi-Fi proxy utility — that is doing just that. It is turning computers into Bitcoin mining machines and the mining is, technically speaking, legal, as the existence of this feature is buried away in the small print of the end user license agreement (EULA). In fact, the EULA says: As part of downloading a Mutual Public, your computer may do mathematical calculations for our affiliated networks to confirm transactions and increase security.
