Following a massive security breach announced in September, Yahoo has recently announced another security breach that may have affected more than one billion accounts.
The incident is believed to have occurred in August 2013 where an “unauthorized third party” stole user data from what is believed to be more than one billion accounts.
The data may have included names, email addresses, telephone numbers, passwords, dates of birth, and encrypted or unencrypted security questions. Financial information was not thought to be stolen.
Yahoo is notifying users who may have been affected and is requiring users to change their passwords. However, the company has also admitted that the hackers stole Yahoo’s source code, which allowed them to access accounts without passwords.
BMS Recommendation: At this time, we strongly suggest if you have a Yahoo account to close it immediately and switch to another email provider such as Gmail. In addition, we recommend that you change all passwords and security questions on any other website where you may have used answers similar to those used on your Yahoo account in order to protect your online privacy and data.
