According to analysis from different sources, Yandex source code does not contain user data, but it does contain over 1,900 factors for ranking search results and more.

The source code repository of the Yandex search engine and technology giant was leaked as a torrent, containing over 1,900 factors for ranking search results. The company, also called Russian Google, had the data leaked on Brached Forums, a hacker forum that surfaced as an alternative to the popular and now-seized Raidforums.

In September 2021, the Russian search engine giant was hit by one of the largest DDoS attacks powered by 200,000 compromised IoT devices.
