Yahoo reports massive data breach involving 1 billion accounts

Computerworld:

In what is likely the largest data breach ever, Yahoo is reporting that data associated with more than 1 billion user accounts was stolen in August 2013.

The incident is separate from a breach Yahoo reported in September involving at least 500 million users that originally occurred in late 2014 and shook public trust in the company.

Stolen user data from this new breach involves names, email addresses, telephone numbers, dates of birth, and hashed passwords using an aging algorithm known as MD5 that can be cracked.

If you don’t absolutely need it, you really should delete your Yahoo account.

  1. I could care less about Yahoo but I do care about Flickr so, I need to keep a Yahoo account (password unique and changed regularly) to keep my Flickr account going. Sigh.

  2. If I were Verizon, I’d let this one go, but at the very least renegotiate a better deal.

  3. My issue is not with Yahoo. That account can die, and I’ll be fine. My issue is that the security questions were leaked. You know, the security questions which are almost entirely the same variation on each other for every website on the planet. So now, even if my passwords are unique everywhere, someone can still compromise my accounts. I wish 1Password supported auto-saving security questions and answers.
