I have been testing the twitter kit in fabric. I added login with twitter integration to my application. I pushed the application to my android phone , clicked login with twitter. entered my username and password.
Searched my logcat for everything with the word "twitter" in it. I found the oauth token getting leaked via login with twitter integration on Fabric. So any app that is using fabric's twitter kit ( login with twitter) is vulnerable to it. Any other app installed on that particular phone hasaccess to logcat, and can read the logs. which results in oauth token stealing.
