What to do if you've ever had a Yahoo account (Huge data breach)
Verge ^ | Sep 23, 2016 | Russell Brandom

Posted on 09/24/2016 1:22:46 AM PDT by aquila48

Yesterday, Yahoo confirmed a data breach affecting 500 million accounts, including logins, names, logins, birthdays, and security questions. The good news is that the passwords were encrypted with a strong hash algorithm, so they’re relatively protected for now. The bad news is, the breach happened in late 2014, so all that data has been kicking around for nearly two years.

It’s too early to say exactly which users are in the dump, but the number is so large that if you are a Yahoo user — or even just a human being on Earth — the odds are pretty good that you’re in there somewhere. In case you are, here are a few quick things you can do to make sure nothing from the breach ends up coming back to you.

Change your password and your security questions Yahoo’s already started doing this, and the strong hash on the passwords means it will take a lot of time and computing power before any criminals can actually get the passwords i,n unencrypted form. Still, better safe than sorry. Change every password and security question linked to Yahoo, Flickr or Tumblr — it's easy to do, and it will make a huge difference if the hackers have any surprises in store.

Use a password manager If criminals ever do break through that password hash, the damage will go far beyond Yahoo itself. The most popular attack in these situations is something called a credential stuffing attack — running the Yahoo login / password pairs against other sites to see if anyone used the same password for both services.

Experts say that, on average, 2 percent of passwords in a given dump will match with a given site. In this case, that means 10 million people, or roughly the population of Portugal.

"Change your password and your security questions...Yahoo’s already started doing this"

They've recently sent me alerts advising me to change my password, along with an option to delete the security questions altogether.

I've always thought that the security questions were a bad idea, because anyone who knows you and your e-mail address could potentially get into your account claiming they lost their password. All they'd need do is enter your Yahoo e-mail address, click "lost password", then answer some very basic questions about you, such as, "what is the name of your spouse?"

This is how they hacked Sarah Palin's account. Can't believe she actually put down accurate responses to these very general questions about herself. You can of course put down anything as a response, as they do not check, or ask to verify. This would seem the sensible way to go about it. Common sense, it seems, isn't very 'common' anymore.

Account Security Issue 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.
 
Below are FAQs containing details about this issue and steps that users can take to help protect their accounts.

What happened?

A recent investigation by Yahoo has confirmed 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. We are working closely with law enforcement authorities and notifying potentially affected users of ways they can further secure their accounts.

Was my account 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.

Is the state-sponsored actor still in Yahoo’s network?

The ongoing investigation has found no evidence that the state-sponsored actor is currently in Yahoo’s network.

What information was stolen?

The stolen user 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.

What is a "hashed password"?

Hashing is a one-way mathematical function that converts an original string of data into a seemingly random string of characters. As such, passwords that have been hashed can’t be converted into the original plain text password.

What is "bcrypt"?

Bcrypt is a password hashing mechanism that incorporates security features, including salting and multiple rounds of computation, to provide advanced protection against password cracking.

I think I received an email about this issue. How do I know that it is really from Yahoo?

Click here to view the content of our notice to affected users. Please note that the email from Yahoo about this issue will display the Yahoo Purple Y icon icon when viewed through the Yahoo website or Yahoo Mail app. Importantly, the email does not ask you to click on any links or contain attachments and does not request your personal information. If the email you received about this issue prompts you to click on a link, download an attachment, or asks you for information, the email was not sent by Yahoo and may be an attempt to steal your personal information. Avoid clicking on links or downloading attachments from such suspicious emails.

What is Yahoo doing to protect my account?

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.

How do I change my password or disable security questions and answers?

You can change your Yahoo password or security questions and answers by clicking here.

Is there anything I can do to protect myself?

We encourage all of our users to follow these security recommendations:

  • Change your password and security questions and answers for any other accounts on which you use the same or similar credentials as the ones used for your Yahoo Account.
  • Review your accounts for suspicious activity.
  • Be cautious of any unsolicited communications that ask for your personal information or refer you to a web page asking for personal information.
  • Avoid clicking on links or downloading attachments from suspicious emails.

Additionally, please consider using Yahoo’s Account Key, a simple authentication tool that eliminates the need to use a password altogether.

What additional steps can I take to protect my information?

Although the affected account information did not include unprotected passwords, email content, payment card data, or bank account information, we encourage you to remain vigilant by reviewing your account statements and monitoring your credit reports. Below is contact information for the three consumer reporting agencies from which you can obtain a credit report.

Equifax Equifax Credit Information Services, Inc.
P.O. Box 740241
Atlanta, GA 30374
1-800-525-6285 www.equifax.com
Experian Experian Inc.
P.O. Box 9554
Allen, TX 75013
1-888-397-3742 www.experian.com
TransUnion TransUnion LLC
P.O. Box 2000
Chester, PA 19022-2000
1-800-680-7289 www.transunion.com

You also may wish to place a “security freeze” (also known as a “credit freeze”) on your credit file. A security freeze is designed to prevent potential creditors from accessing your credit file at the consumer reporting agencies without your consent. There may be fees for placing, lifting, and/or removing a security freeze, which generally range from $5-$20 per action. Unlike a fraud alert, you must place a security freeze on your credit file at each consumer reporting agency individually. For more information on security freezes, you may contact the three nationwide consumer reporting agencies or the FTC as described above. As the instructions for establishing a security freeze differ from state to state, please contact the three nationwide consumer reporting agencies to find out more information.

The consumer reporting agencies may require proper identification prior to honoring your request. For example, you may be asked to provide:

  • Your full name with middle initial and generation (such as Jr., Sr., II, III)
  • Your Social Security number
  • Your date of birth
  • Addresses where you have lived over the past five years
  • A legible copy of a government-issued identification card (such as a state driver’s license or military ID card)
  • Proof of your current residential address (such as a current utility bill or account statement)

You have the right to obtain a police report and request a security freeze as described above. The consumer reporting agencies may charge you a fee of up to $10 to place a security freeze on your account, and may require that you provide certain personal information (such as your name, Social Security number, date of birth, and address) and proper identification (such as a copy of a government-issued ID card and a bill or statement) prior to honoring your request for a security freeze. There is no charge, however, to place, lift or remove a security freeze if you have been a victim of identity theft and you provide the consumer reporting agencies with a valid police report.

For U.S. residents, you can contact the FTC to learn more about protecting your personal information. The contact information for the FTC is below:
 
Federal Trade Commission
Consumer Response Center
600 Pennsylvania Avenue, NW
Washington, DC 20580
1-877-IDTHEFT (438-4338)
 
For Rhode Island residents, you may obtain information about protecting your personal information from the Rhode Island Office of the Attorney General at:
 
Rhode Island Office of the Attorney General
Consumer Protection Unit
150 South Main Street
Providence, RI 02903
(401)-274-4400

Are Tumblr accounts affected?

No. The systems from which the data was stolen contained no Tumblr user data at the time of the theft.

How can I get help with my account?

If you need further information or assistance with your account, please visit https://help.yahoo.com, where you will find the latest information and may be able to access direct customer support. Please DO NOT ENGAGE with fraudulent online fee-based, toll-free-number services PRETENDING to be Yahoo support. Please note: Yahoo channels all support through https://help.yahoo.com.

Never had a Yahoo account, nor do I have a Google account, no need to. As an online veteran for nearly 30 years starting with CompuServe, local BBS's, and an original AOL user back in the early 90's, I've learned not to trust any online entity.

Yahoo was/is a search engine as far as I'm concerned, Google too ... I have no use in establishing any sort of 'account' with any of 'em ... I use 'em as a search engine and that's all. They may be tracking my searches, but at least they don't have definite email or personal info on me.

Screw Yahoo and Google.

When answering security questions add a number combination after the answer. That usually helps stop someone from answering correctly.

Whenever I’m asked for security questions I always put an answer that is incompatible with the question.

Example: if the question is: What was the name of your elementary school?

Instead of entering the name of the school I will put in a number like 7685948 that only I will remember. It will for sure beat anyone trying to guess your security question and only you will ever know it is a number instead of a name. they can guess at school names all day long and never get it right. I keep a record of the numbers written down but never so anyone could connect them to any sites.

Always worked for me.

It looks like they have disabled access to my security questions.

How do I know which security questions were compromised? I have no idea how exposed I am. Yahoo is not helping me here.

I dumped Yahoo years ago. Got tired of all the ads slowing down the email client. And the user interface sucked.

I really hated having to go search for our small white poodle cross when I was in high school. Calling 'Flower' as I paraded threw our neighborhood was embarrassing.

But thanks to my mother's strange naming conventions, the answer to the security question 'The name of your first dog,' just might through them off the scent.

Absolutely agreed, except if you have a Droid phone Google pretty much forces you to have an email account with them. MSFT makes you establish an account with them in order to license their Office product for f$$k's sake. I've never used either of those accounts, and despise the fact that I even have to have them, but their products, their rules, unless you don't want to have a phone or be able to use MSFT's market monopoly software.

Apple has the same rule BTW - you have to have an account with them.

Ah, CompuServe, there were some interesting times over there (sorry to digress here). I was an Adm. Moderator, or whatever we called them at the time, on several forums, and we admonished people if there were any personal attacks against other members. And people were supposed to use real names, which many did. I remember thinking of branching out on the Internet back then as venturing into the “Wild West”, couldn't believe how relatively sheltered CIS seemed. The early 90’s were fun, when TAPCIS came out it made my life much easier. And I still remember some of the malcontents who loved Clinton in his first bid for POTUS. Tried to set them straight, while being courteous, of course, LOL.
