Spy in your pocket

Specialists of the US Naval Marine Systems Development Department (NAVSEA), together with the guys from Indiana University, conducted an interesting experiment : Twenty volunteers were given smartphones with specially designed spyware installed on them.
Malicious software takes pictures and sends them to the server, and data from other sensors of the smartphone is also transmitted. On the server, a three-dimensional model of the room is built from photographs using data from motion sensors and the position of the apparatus. On average, the models obtained were quite detailed - they contained about 180-800 thousand three-dimensional points. For orientation in them, a special client software was compiled, which allowed to examine in detail the individual details of the photos.
After the received models were transferred to two groups of volunteers, whose task was to search for secret information (passwords, credit card numbers, location of hidden safes) on the received models. In this case, one group was provided with photographs, and another - the resulting three-dimensional model. According to the authors, the three-dimensional model, unlike photographs, turned out to be much more convenient for this — stealing sensitive information with its help turned out to be much easier.
In their article, experts emphasize that they were motivated to create a program by exploring hidden vulnerabilities arising from the use of modern smartphones.
At the end of the article, the authors also give typical recommendations for protecting smartphones from such software, such as not to root the device and use antivirus. As they say, [paranoia ON].
