I use Bluestacks on my pc in order to emulate Whatsapp. I downloaded Whatsapp apk through my gmail account enabling app sync on Bluestacks and my Google Play account. This morning I was asked to review my account due to suspicious (recent) activity. After confirming the security codes and questions to enable my gmail account once more, I decided to look into the security features of my gmail account to see which devices have been connected to or tried to access my account and notices a picture of a SAMSUNG GALAXY NOTE 3 with the description "SAMSUNG-SM-N900A" below it with an online status which was synced to my gmail account. (copy pasted the note) Samsung Galaxy Note 3 Last synced: January 1, 2015 at 11:38 PM Find your Android devices with Android Device Manager I attempted to locate the device but was unable to do so due to fact its google location feature was not enabled. It also gave me the options to ring the device and or lock and erase all data. (copy pasted info) SAMSUNG-SM-N900A Contacting your device... Ring Enable Lock & Erase But it was unable to contact the device but when I ring it the bluestack app begins to ring..... I am confused if I have been hacked or indeed the bluestacks emulator uses Samsung Note 3 for whatsapp purposes and automatically syncs with my gmail account... Any info regarding this issue will be very appreciated, Thanks!!
