Vulnerabilities of android data sharing and malicious application to leaking private information

Smartphones are not just phones but also portable computers, providing diverse services needed in life including calls, texts, emails, GPS, camera, Wi-Fi and Bluetooth apps. These apps keep and manage diverse intrinsic data as well as sensitive private information such as address books. Smartphones enable swift and easy data exchange via 3G, 4G and Wi-Fi. Thus, personal information stored on Smartphones is prone to leakage. Particularly, ContentProviders provided by Android to share data between apps are susceptible to illegitimate leakage of data. The present study analyzes the vulnerabilities of ContentProviders and implements a malicious app to implicate risks related.
