Did someone hack my iPhone?

Hi Guys, I have received a phising message on 20th October that i did NOT click, however I noticed that my phone started sharing location with this contact (10:28) then stopped it (10:32) then it sent the point of my location (10:36). Is it possible that i got hacked somehow? Around this time I was on a photoshoot with my 6 months old son and there is a slight possibility that he could do this from my applewatch but honestly i doubt it. What do you think i shoul do? Could someone hacked my phone? Are they able to access my mobile bank as well? Thanks in advance!
