Newfound security hole in the LG G3 made user data on it prone to intruders
If you're still rocking the LG G3 (pretty much the best Quad-HD smartphone $270 can buy), you might have been bugged about installing a Smart Notice patch recently. Smart Notice is a service that shows recent notifications in the form of cards, similar in style to Google Now. It is enabled by default on LG devices.
According to the source, the vulnerability is only present on the LG G3 at the moment, although Smart Notice is also found in the LG G4 and other recent LG handsets. So, if you receive an updated version of the app, you'll know what's up.
The researches at BugSec say they don't know of any cases in which the vulnerability has been exploited, be it by attackers or malware scripts. However, they do insist that the vulnerability is not merely theoretical, and the fact that LG patched up Smart Notice so soon after having it brought to their attention lends it enough credibility by itself.
