Hacking

That is a Rogue Calendar account. 

You are using iOS 14, Go to Settings ➔ Calendar ➔ Accounts and under Accounts see if an unknown calendar account is listed. If it is then tap on it and then Delete account.

Note that it is not a virus. It is something that got added to your calendar because you may have accepted an offer from a pop-up on a website unknowingly. Please be careful out there.

Hi @stan_abdul

i have seen your post but i want to tell you that everything is possible if you allow every app to access your phone. in specious case if you feel anything is going against and you think that its hacking then you can simply reset your phone or cantact to administrator/iphone support.

if you are still confused please let me know

Many thanks
