About a month ago, one billion of Yahoo Accounts has been compromised. Today I received two emails from yahoo in my gmail accounts, they were saying that my yahoo password has been changed and my recovery email has been removed (+ a lot of warning emails of old accounts of forum and games that were receiving unknown accesses, but nvm). In the email which informed me about the recovery, I saw a link that would have allowed me to restore the old account, but before to click I thought "Wait! I had like 10 yahoo accounts. What account am I saving?" I check, I read, I read again, but nothing, no information about it in the text. Nevermind, there's a link. This link will be related to a specific account. Right? Wrong. I click, it sends me in a generic page. The link is mute. I attach a screenshot, you can see where the link points in the left-bottom corner. So now I know that one of my accounts has been hacked, I don't know WHICH account has been hacked and I'm not able to recover my account. Luckily it wasn't my main inbox!
