Abstract
A method for detecting instances of exfiltration by an application. The method includes performing a first set of runs on a first computation device, and performing a second set of runs on a second computation device. Each set of runs involves running the application a plurality of times; and for each run, capturing packets transmitted by the computation device. In some embodiments the packets within the first set of runs are compared to identify differences caused by environmental noise, such as run-to-run changes in the information sent to the first device by remote servers. Comparisons between (i) runs performed on the first device and (ii) runs performed on the second device, with differences caused by environmental noise removed, may then be used to assess whether the application exfiltrates personal information, such as a phone number, that has different values on the first device and on the second device.
