A security researcher found a possible exploit in Microsofts PowerPoint that would let an attacker run an application when the user simply hovers with the mouse over a link. The action can link both to a local file and a remote one, since SMB connections in Windows 10 are possible over the Internet, even when the ports are closed. Microsoft fixed this vulnerability a while ago, so it’s no longer possible to run local apps in this manner. Similar attacks are used right now that involve the use of Macros in Office files.”]
