Android Security Survey
Is Your Android App Telling Advertisers Where You Live?
A study (pdf) conducted by Intel Labs and researchers at Duke University has found that 15 out of 30 third-party applications were passing on users' data to remote advertising servers.
Researchers used the TaintDroid taint tracking and analysis system to leverage Android's virtualised execution environment and perform realtime analysis on the behaviour of 30 popular third-party Android apps. They reported 63 instances of potential misuse of users' private information across 20 applications, and found that 15 of the 30 applications reported users' locations to remote advertising servers.
"Our findings demonstrate the effectiveness and value of enhancing smartphone platforms with monitoring tools such as TaintDroid," concluded the study.
