Sabotage

With a computer or a network, sabotage is deliberately disrupting one or more aspects of its functionality. These acts may involve changing settings without authorization or uploading malware. In some extreme cases, sabotage can refer to the destruction of a company's property or even violence.

On the Internet, causing another user or company grief by libelling or doxxing them may be considered sabotaging.
