As the biggest known hack of all time it seems to be hacking and leaking of accounts of Yahoo company as the exposed accounts were revealed to reach about 3 billionmillions.
Η Yahoo, which was acquired this year by Verizon, now believes that the total number of accounts that were violated in August of 2013, and revealed last December, was not 1 billion, but it's 3 twice !!!! And so this particular hack is the biggest in the history of the internet.
Late last year, Yahoo revealed that it had suffered a massive data breach in August 2013 that affected 1 billion user accounts. The leaked information included names, email addresses, phone numbers, dates of birth, passwords, and in some cases, "encrypted or unencrypted questions and answers security».
At the time, Yahoo had confirmed that the hackers did not collect data bank account or credit card details associated with Yahoo accounts.
But on Tuesday Verizon made the deal following announcement: "Μετά την εξαγορά της Yahoo από την Verizon, και κατά τη διάρκεια ολοκλήρωσης των διεργασιών, η εταιρεία έλαβε recently new data and now believes, after investigation and with the help of outside expert investigators, that all Yahoo user accounts were affected by the August 2013 theft.”
The statement clearly shows that if you had a Yahoo account on 2013, then your data has definitely been violated.
So for whatever reason, if you have not changed your password since then, you will need to change it right now and activate 2FA authentication.
Also, if you use the answers to security questions, change them immediately. You mean that if you use these passwords or security responses in other non-Yahoo accounts, the best thing to do is make immediate changes.
Deleting your Yahoo account is not a good thing choice, as the company deletes these accounts after 30 days, which allows the hacker to break in. So, even if you don't want to use your Yahoo account, just enable 2-factor authentication and leave it at that.
Yahoo has begun the notification of affected account holders by asking them to change their codes directly, and assuring them that stolen data "does not include passwords in plain text, card numbers, or bank accounts."
It should be noted that this violation is different from violation of 2014 which happened again in Yahoo, which was revealed in September last year, affecting as much as 500 million user accounts.
