Help Security issue on open wifi

[JAy3001]

Just back from our holidays and have been using the resorts wifi connection along side my VPN. (SurfEasy)

The resort wifi was a little inconsistent dropping as you walked around, most of the time the VPN will drop off awaiting the connection again. Then it would spring back into life, sadly it did not do this all of the time and once I noticed this I would kill the wifi connection when not in use to eliminate the issue.

Having come back I noticed that in my calendar app (samsungs calender) that an event had been added from the date it was added right thru to the end of the year. It was full in detail telling me my iPhone x was ready for pickup and provided a dodgy shortened amazon link. I removed these entries straight away.

So, how did this happen? Any ideas if my device may have been compromised because of the lack of VPN cover? I've seen nothing else dodgy such as apps or processes.

I have installed SkyView free at a wedding the day after we landed to entertain the kids. Thou I have not seen any bad reviews for this app and was recommended by google..

Too be safe, I would start by changing your password, and then add 2 step verification, this way once logged in from somewhere else of a different device you will notified. That's a good place to start.

So to make sure, this only applies to events that were added by Google, not events that were added by you ??
