Teh-fed.ru

In 2014 a significant database from the Russian telephone directory service Teh-fed.ru was exposed. The incident involved the public disclosure of a large scale reference book containing sensitive personal details of approximately 632 thousand residents across Russia. The data appears to have been formatted as a searchable directory including full names and contact information. The breach highlights the vulnerability of local directory services and the risks associated with the centralized storage of resident identification data during that period.
