Fraudulent log in attempt
Hi there... I got a notification as I was working that someone was attempting to log into my iCloud account. A screen popped up with a map requesting approval, then disappeared quickly. Before I could click cancel, it happened again in another location, then disappeared quickly. I think both locations were in Russia, but I am not certain. I immediately changed my iCloud passcode. Any idea what happened and anything else I should do? I am concerned.
