it found researchers from the University of California at Berkeley, the University of Calgary and the University of Madrid Karl III. They found that if a certain application on your smartphone have permission, it can provide the information and another. Enough to these programs were created on the same software development kit (SDK).
Among these applications - a program from Samsung and Disney, have been downloaded hundreds of millions of times. Their developers use the SDK from the Chinese search giant Baidu and research firm Salmonads. This SDK can transfer data from one application to another, as well as on the servers of the companies mentioned.
Among all the applications the researchers noted photo service Shutterfly. He sends GPS-coordinates on the company's servers without the permission of the location tracking. This application receives information from the EXIF-data capture, which is stored
in pictures. However, service developers assuredThat without the permission of the data is not collected.All of these, as well as several other vulnerabilities, researchers have notified Google back in September of last year. As a result, the Californian giant has promised to fix them Android Q, Which has been established only in about 10% Android users. With regard to other versions of the operating system as long as a word, but, Google may release the updates for them.
