Yahoo confirms hack, says data from 500 million user accounts stolen

By , Sep 22, 2016


Yahoo on Thursday confirmed that certain user account information was stolen from the company’s network in late 2014. Recode has the official statement, which says that it believes more than 500 million users were affected by the breach.

The good news is that Yahoo says from what it knows so far, the stolen information doesn’t include payment card data, bank account information, or unprotected passwords. The firm is working closely with law enforcement in its investigation.

“We have confirmed that a copy of certain user account information was stolen from the company’s network in late 2014 by what it believes 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. Based on the ongoing investigation, Yahoo believes that information associated with at least 500 million user accounts was stolen and the investigation has found no evidence that the state-sponsored actor is currently in Yahoo’s network. Yahoo is working closely with law enforcement on this matter.”

Remember that Yahoo is currently in the process of being acquired by Verizon, so this attack could have a major impact on that deal. It sounds like the company hasn’t exactly been upfront with its buyers regarding the seriousness of the breach.

As always, we recommend that you use a separate password for every service, and enable extra security whenever possible.

    What’s yahoo?

    • I now right, fortunately for me yahoo is my spam mail location, nothing important is there at all.

  • triggerhappypunk

    What they don’t tell you is how many people are still using Yahoo. There are probably only 3 people that are in a panic right about now!

    • Diego Milano

      I must know all three of them then (literally: my mom, a friend, and my ex).

    • Jayy

      • omakad

        They are trying to be funny. Millions use Yahoo. Though Yahoo used to be the place to be and search engine to use. That was before Google.

      • Jayy

        Oh okay, I thought they were saying me using yahoo as one of my emails is the equivalent of still logging into AOL instant messenger or MySpace.

      • Anyone remember Ask Jeeves lol

      I use their sports app so I have a yahoo login. also use that yahoo login for iMessages and FaceTime because my wife, my son, and I all share the same iCloud account (to share contacts, reminders, etc across devices — apple’s family sharing isn’t very good).

  • TornBodies

    So they sat on this info for 2 years. I haven’t used yahoo since they got rid of chat 2006

    • Xee

      Exactly why has it taken then since 2014 to almost end of 2016 to come clean on this?!

  • Bill

    The new Yahoo Messenger client is the worst thing that ever happened to human history anyway.

  • Bugs Bunnay

    Anyone familiar with haveibeenpwned dot com? On going investigations “suggests” stolen info did not include this and that, the other site says otherwise.

  • Liam Mulcahy
