It seems that the US company Yahoo continues to pursue setbacks. In August this year, the company found that data from its servers had been stolen, including user names, passwords, and letters. As a result of the hacker attack, more than one billion accounts were affected. The year has not yet come to an end, and Yahoo security experts have missed the personal data of another one billion of its users.
The massive data leak was unveiled by the company's security chief Bob Lord in an official statement on the Yahoo page (which officially belongs to the search engine). It is well known that the leakage occurred when US law enforcement agencies discovered the freely available data of users of Yahoo services on the Net. Only when the company's security engineers checked the data for authenticity, it became clear that they are dealing with another hack. And different from what happened in August.
Traditionally stolen data includes names, mailbox addresses, phone numbers, dates of birth, passwords hashed using the MD5 algorithm (successfully cracked as early as 2013), as well as encrypted and non-encrypted control questions and user responses to them. The leak did not include unencrypted passwords, credit card details, and other bank information. According to an official statement from Yahoo security chief, payment information was stored in a completely different system that was not attacked. If you have personal accounts in Yahoo services, (Tumblr, Flickr, Flurry), we strongly recommend that you change your password.
