- It’s 3 Billion! Yes, Every Single Yahoo Account Was Hacked In 2013 Data Breach
Yahoo! is a one of the largest web services provider, wholly owned by Verizon Communications through Oath Inc. and headquartered in Sunnyvale. Yahoo provides various services including e-mail services. Late last year, Yahoo revealed that the company had suffered a massive data breach in August 2013, which affected 1 billion user accounts. But according to the latest report, it is not 1 billion user account which were hacked but rather 3 Billion. The record-breaking Yahoo data breach affected every user on its service at that time. The 2013 hack exposed user account information, including names, email addresses, telephone numbers, dates of births, hashed passwords (using MD5), and, in some cases, “encrypted or unencrypted security questions and answers,” Yahoo said in 2016. Yahoo did confirm that hackers did not obtain bank account details or credit card information tied to the Yahoo accounts.
Cyber Security Tips: Users are strongly recommended that, if you did not change your password last year after the disclosure of this massive breach, you should now change your passwords immediately, enable two-factor authentication, keep monitoring your account, regularly change your password, avoid using same e-mail for different accounts and beware of phishing.
