| Abstract | We describe a novel class of attacks called denial-of-app that allows adversaries to inhibit the future installation of attacker-selected applications on mobile phones. Adversaries can use such attacks to entrap users into installing attacker-preferred applications, for instance to generate additional revenue from advertisements on a competitive app market or to increase the rate of malware installation. Another possibility is to block anti-virus applications or security workarounds to complicate malware detection and removal. We demonstrate such an attack that works on arbitrary unmodified stock Android phones. It is even possible to block many applications from a list predefined by the attacker instead of just a single app. Even more, we propose an attack for banning applications from Google Play Store regardless of the user's phone by exploiting similar vulnerabilities in the market's app vetting process. Unblocking an application blocked by our attack requires either root privileges or a complete device reset. The Android security team has confirmed and fixed the vulnerability in Android 4.4.3 (bug 13416059) and has given consent to this publication within a responsible-disclosure process. To the best of our knowledge, the attack applies to all versions prior to Android 4.4.3. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
