Abstract
The present disclosure relates to detecting security risks from application packages signed using a key based on differences detected between application packages. An example method generally includes calculating a difference score for a first application package signed using the key. The difference score may be based on differences detected between content of the first application package and content of one or more second application packages signed using the key. A computing system calculates an average difference score from the individual difference scores. Upon determining that the difference score for a specific application package of the second application packages exceeds the average difference score by a threshold amount, the computing system sets a reputation associated with the specific application package to an unknown reputation and generates an alert indicating that the specific application package is a potential security risk.
