Yahoo say hackers may have stolen information from 1 Billion accounts
A hack on Yahoo in 2013 may have led to one billion users having their data stolen, according to the company today.
The company also believe that this is a different hack to the one that hit 500 million accounts that the company disclosed earlier this year.
"Yahoo believes an unauthorized third party, in August 2013, stole data associated with more than one billion user accounts," a statement said.
"Yahoo believes this incident is likely distinct from the incident the company disclosed on September 22, 2016."
The good news for Yahoo users is that it is believed the hackers did not obtain information like passwords, bank details or credit card numbers.
However, information they may have obtained includes names, email addresses, telephone numbers, dates of birth, "hashed" passwords and possibly security questions and answers.
Yahoo's advice for their users is:
- Change your passwords and security questions and answers for any other accounts on which you used the same or similar information used for your Yahoo account;
- Review all of 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; and
- Consider using Yahoo Account Key, a simple authentication tool that eliminates the need to use a password on Yahoo altogether.
