Got the message from yahoo today when tried to log in to my account. Here is what in their security FAQs
"We have confirmed, based on a recent investigation, that a copy of certain user account information was stolen from our network in late 2014 by what we believe is a state-sponsored actor. The account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (the vast majority with bcrypt) and, in some cases, encrypted or unencrypted security questions and answers. The ongoing investigation suggests that stolen information did not include unprotected passwords, payment card data, or bank account information; payment card data and bank account information are not stored in the system that the investigation has found to be affected."
"We are notifying potentially affected users by email and posting additional information to our website. Additionally, we are asking potentially affected users to promptly change their passwords and adopt alternate means of account verification."
"We have taken action to protect our users, including:
- We are notifying affected users.
- We are asking affected users to promptly change their passwords and adopt alternate means of account verification.
- We invalidated unencrypted security questions and answers so that they cannot be used to access an account.
- We are recommending that all users who haven't changed their passwords since 2014 do so.
- We continue to enhance our systems that detect and prevent unauthorized access to user accounts.
- Our investigation into this matter continues."
I wonder why it took them 2 years to realize that they have security breach, and who is that country-sponsored actor? Which country?
It's interesting because a couple of month ago I was pushed to change the yahoo password "for security reasons". So, why only now they came out of closet?
