Yahoo released an important message about Yahoo User Security on the official company blog a moment ago confirming that information on at least 500 million Yahoo accounts was stolen in late 2014.

The company believes that a state-sponsored actor is behind the attack. According to the blog post, names, email addresses, telephone numbers, birth dates, hashed passwords, and in some cases encrypted or unencrypted security questions and answers were stolen.

Yahoo states that there is no evidence currently that unprotected passwords, payment card data, bank account information or other financial information were among the stolen data.

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.

Yahoo plans to inform affected users starting doing. The message that the company plans to send out may differ from region to region. You can check the U.S. message here (PDF document).

The email includes information on what happened, what information was involved, what Yahoo is doing, and what individual users can do about it.

Yahoo will ask users that are affected to change their passwords and add alternate means of account verification to the account. The company has invalidated any unencrypted security questions and answers, and recommends that users who have not changed their Yahoo passwords since 2014 to do so immediately.

To change the Yahoo password, do the following:

  1. Load the Yahoo Account page.
  2. Click Account Security, and then on change password.
  3. Enter and confirm your new password.
  4. Click on continue, and then on continue again to complete the process.

Yahoo asks users furthermore to change account passwords and security questions/answers for any other account that has been associated with the Yahoo account, or where the same email address and password were used.

Yahoo users should expect to get spam communications and emails that may be personalized.

One option to strengthen the security of the Yahoo account is to use Yahoo Account Key. This is an authentication tool that is integrated into the Yahoo application for Android and iOS, and available for set up from a web browser as well.

Additional information about Yahoo Account Access are available here.

Closing Words

It is rather frightening that information about year-old hacks that dumped millions of user account information come to light years later only, if at all.

It is clear that anyone with access to the data had years to exploit the information and decrypt passwords. While it makes sense for Yahoo to inform users now that they need to change passwords on Yahoo and on third-party sites if username and password was shared, it may very well be too late for a lot of accounts.

Now You: Are you affected by the security breach?

    Martin, I would appreciate that you do not censor this post, as it’s informative writing.

    Onur, there is a misleading statement “[…] GIFs are animated images …”. No, obviously you don’t seem to have take much notice of what you were told back in March regarding; Graphics Interchange Format (GIF).

    For example, https://www.ghacks.net/2023/03/31/whats-gif-explanation-and-how-to-use-it/#comment-4562919 (if you had read my replies within that thread, you might have learnt something useful). I even mentioned, “GIF intrinsically supports animated images (GIF89a)”.

    You linked to said article, [Related: …] within this article, but have somehow failed to take onboard what support you were given by several more knowledgeable people.

    If you used AI to help write this article, it has failed miserably.

    Martin, [#comment-4569908] is only meant to be in: [https://www.ghacks.net/2023/07/09/how-to-send-gifs-on-iphone-two-different-ways/]. Whereas it appears duplicated in several recent random low-quality non relevant articles.

    Obviously it [#comment-4569908] was posted: 9 July 2023. Long before this thread even existed… your database is falling over. Those comments are supposed to have unique ID values. It shouldn’t be possible to duplicate the post ID, if the database had referential integrity.

    GateKeeper ?

    That’s called “appointing” businesses to do the state’s dirty work!!!!!

    But the article says itself that those appointed were not happy – implying they had not choice!!!!!!

      Rreedom of Association is one of our most important rights. Some people think it’s Freedom, but no, I say Rreedom is far more important. There are many STATE-MANDATED associations that save jobs, that’s right MANDATED. I can’t name any of them, but rest assured they are bad, because saving jobs are bad, and people having jobs leads to dictatorship!!! Anyone who disagrees is too radical for Ghacks maybe, because I’m not sure.

    Note: I replaced the quoted URI scheme: https:// with “>>” and posted.

    The current ghacks.net is owned by “Softonic International S.A.” (sold by Martin in October 2019), and due to the fate of M&A, ghacks.net has changed in quality.

    Many Authors of bloggers and advertisers certified by Softonic have joined the site, and the site is full of articles aimed at advertising and clickbait.

    As it stands, except for articles by Martin Brinkmann, Mike Turcotte, and Ashwin, they are low quality, unhelpful, and even vicious. It is better not to read those articles.

    By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).

    We all live in digital surveillance glass houses under scrutiny of evil people because of people like Musk. It’s only fair that he takes his turn.

    “Operating systems will be required to let the user choose the browser, virtual assistant and search engine of their choice. Microsoft cannot force users to use Bing or Edge. Apple will have to open up its iOS operating system to allow third-party app stores, aka allow sideloading of apps. Google, on the other hand, will need to provide users with the ability to uninstall preloaded apps (bloatware) from Android devices. Online services will need to allow users to unsubscribe from their platform easily. Gatekeepers need to provide interoperability with third-parties that offer similar services.”

    Wonderful ! Let’s hope they’ll comply with that law more than they are doing with the GDPR.
