Abstract: An apparatus, method and computer program product for repairing security vulnerabilities of an application running on a mobile device. The method comprises: monitoring, by a hardware processor running a mobile device application, an application program interface (API) request associated with a data access operation, the data access operation associated with a security vulnerability. The method determines one or more private values provided by the data access operation and tracks, for each determined private value, a use of the private value by the mobile device application. Further, the method determines from the tracked usage, whether a private value has been transformed in a manner associated with the security vulnerability. For each private value that has been transformed, using the processor to modify the private value deemed a security vulnerability prior to an access by the mobile device application.

Abstract: A computer system performs tracking of security context for confidential or untrusted values input from sources in an executing application to sinks in the executing application. The security context includes indications of sources and declassifier methods corresponding to the values and has been previously defined prior to the tracking. Prior to release of a selected confidential or untrusted value by a sink in the executing application, security context is fetched for the selected confidential or untrusted value. A selected declassifier method is caused to be used on the selected confidential or untrusted value prior to release of the selected confidential or untrusted value to the sink. The selected declassifier method obfuscates the selected confidential or untrusted value and is selected based on the security context for the selected confidential or untrusted value. The obfuscated confidential or untrusted value is caused to be released to the sink in the executing application.
