Thanks for this post. How do things change if you use the default Messenger app vs. Hangouts? I just updated my Messenger app settings to uncheck these options, but when I went into Hangouts to check there, "Auto retrieve MMS" was checked, but all of those boxes were greyed out and it said "SMS disabled - Touch to make Hangouts your default SMS app". So the question then is whether that is a sufficient indicator that Hangouts is not used, and is Hangouts still vulnerable if I am just using the default Messenger app? EDIT: Stock Nexus 4 running vanilla Android 5.1.1

You should only have to disable MMS auto retrieval in the default SMS app.

You'll want to disable auto MMS retrieval in whatever your default SMS/MMS client is. And thank you for mentioning Messenger -- we just updated the post to include instructions for it as well.

  NP. Is there anything to look for in past MMS's that could be indicative of an attack? Would it always be an unknown user with a video attachment? Or could they spoof a known user? Since it has been in the wild for a while, I'm now wondering what I can do to look for symptoms of an infection.
