Phonelog: missed call "NULL" name and number

(null), phone getting hacked? - Apple Community
Nothing happened once I pressed it. Anyway, is it possible for an iPhone to be hacked or get a virus? Should I be worried? 553 3 ... Thanks for reaching out to the Apple Support Communities!

Without knowing which apps were updating, or seeing the error that appeared, it's hard to say exactly what caused the issue. From what you've described it sounds like (null) replaced another word in the pop-up.

I am unable to add it to my blacklist because the number (NONE) is in an invalid format. This kind of call should NOT even get through. If the phone number is not in a valid format, numeric, etc. it should not be allowed to connect. Last edited by richvanv on Tue Feb 28, 2012 7:10 pm, edited 2 times in total.
