Scrounger – Application Testing Toolkit
Scrounger This tool was inspired by many other tools already published. The second reason is that it solves the vulnerabilities of mobile applications.
The purpose of this application is to create a tool similar to Metasploit that will not allow the execution of a slant, but will help to evaluate it by performing simple tasks that must be performed on all scores.
The difference
The main features of Scrounger that others do not offer:
Works with Android and iOS
Metasploit console and modules
Provides a variety of modules that can be run to give Pentester a starting point
Easily expandable
