Called from 408-610-4900 to verify my new phone number on my Yahoo account. I change my password on the account also. It's a good idea to change your password on your email accounts every 6 months or so. Bank account too.
received a call from this number (408-610-4900) this morning and when I answered there was nobody on the line. I hung up and searched the number and some are saying yahoo and some are saying spam. I am going with spam as I do not deal with yahoo anymore and never will, please beware I think its spam.
Setting up 2-step verification, so requested call: Yahoo called from this number, but ... SILENCE. NO CODE!
(Thanks for the "help," Yahoo, for those of us dealing with your monstrous HACK.)
