Author here. Thanks @mbam_mtbr for encouraging me to post here. Although I'm not a victim, but got involved in the situation by helping a friend. The Batmobi SDK is definitely playing a prime role here. I did give a shoutout to Videoder via Twitter, but they did not respond. I'm now planning to drop a mail to the dev & PR person. As I said in the article, I'm trying to dump the firmware of my friend's phone and do some reversing to investigate possible presence of Batmobi SDK inside Samsung stock apps. I'll post my findings here.
