"Hover With Power" Attack Via PowerPoint Files


A novel hack called “Hover with Power” allows an attacker to create a mouse-over in a PowerPoint file which would trigger the download of malware when a user hovers over a link in the presentation. Utilizing an element of social engineering, the user would then have to accept a pop-up dialogue box to run or install the program. The executable file can also be run from a remote server by using the ‘HyperLink To” action. This attack affects .ppsx files which are designed to play presentations and can’t be edited.
