The latest version of the venerable (and oh-so-holey) PDF viewing routine, Acrobat Reader DC 15.023.20053, released this week, looks for information about your Google Chrome surfing habits. Without your knowledge or consent, the security patch installs a Chrome browser extension that's spyware, pure and simple.
The situation's a little more complex, but for most people using Adobe Acrobat Reader, Chrome spyware comes along for the ride.
If you haven't looked at the Adobe Acrobat Reader lately -- I haven't used it in years, due to security concerns -- this latest privacy twist warrants your attention. Unfortunately, there are three distinct versions of Acrobat Reader making the rounds, and this spyware "feature" affects only one of them.
