Zhilischnik.ru

A massive data exposure involving the Russian state budget institution Zhilischnik occurred in 2021. The incident revealed six years of historical data that was left unprotected in the public domain. The breach exposed sensitive personal information of residents primarily located in Moscow. The leaked data includes full names, residential addresses, and multiple contact phone numbers for approximately four and a half million individuals. This exposure poses significant risks for targeted phishing and social engineering attacks against the affected residents.
