icloud breach
I have received many calls and voice messages today saying my iCloud account has been breached. I got scared and finally picked-up. I was told that someone in Germany has been trying to log into my account and asked if I have traveled there recently or given my information to someone who has traveled there. I was then asked if I purchase anything online. I said yes. I was then told to not purchase anything online for the next 24 hrs. I was then asked if I have a computer. I said yes. I was then asked to share my information with them so they can log into my computer. When I asked what for. I was told so that they can get into my computer and find the people trying to access my iCloud and block them. I immediately hung up. About 5 min later I received another call, which I am blocking.
How do I fix this?
