Strange text message on iPhone7
I received a weird text message (not an iMessage) this afternoon on my iPhone7: Qb@$
The date shown is 11/03/2015 and it has been sent from a device with a 16 figures long number: 1944785494839016
I am now getting a bit paranoid about this. As I have heard about cases of iPhone hacking through text messages in the past, I have immediately changed my AppleID password as well as my primary email address.
Could you please let me know if any further actions need to be taken? (Note: I have updated my device with the latest iOS update 10.0.2)
Thanks for your help!
iPhone 7, iOS 10.0.2
