I'm not sure if this the appropriate website to ask this but ...

Over the past year, at least ten friends and family members have called me because their email was hacked. In every case, it was a Yahoo account. It happened to two of them this week.

I've researched the problem and all I find from Yahoo is: "Yeah, we did have a problem but we fixed it"

Can someone explain what is going on?
