Has my phone been hacked?

[hukkus]

Hello,

A couple of years ago I had a mobile phone with an old android version. I knew nothing about stagefright vulnerabilities and every video I was receiving on my whatsap was automatically downloaded to my phone.

I received several very strange video messages from the same person. It was weird but I didn't suspect too much about it, as I never thought a phone could be hacked just with a video message. Some weeks ago I heard about stagefright related attacks and I suddenly remembered about those messages. I suspect my phone was hacked, and I would really like to be able to know for sure.

Although I don't use it any more, I still have that phone. And I can imagine that it might have some corrupted files, or some malware installed somewhere if it was actually hacked? And that possibly those files or folders cointain information on where the data from my phone was being sent to (maybe to another phone via SMS)?

If any of you knows how to do this or if there is any advice you could give me on how to have some certainty on what happened, it would be very appreciated!

Me neither, that would be very surprising. But if the phone has been hacked -and it seems it has been- I guess there must be some corrupted files somewhere.

Do you know any hackers forum where they can probably be more familiar with this? I am sure the guys doing it know how to detect it as well.

Why do you say "Did you watch the videos from whatsapp? If not, your phone would be fine. Downloading wouldn´t trigger the exploit there." I had read the opposite thing -I don't remember where-
