K-vrachu.ru

In 2016 the Russian medical portal K-vrachu experienced a significant data breach affecting nearly half a million users. The incident resulted in the unauthorized exposure of a database containing sensitive personal information and security credentials. The compromised dataset included full names and dates of birth along with email addresses and passwords stored as MD5 hashes. This method of password storage is considered weak by modern security standards making the accounts vulnerable to cracking. The leak posed a serious privacy risk to patients using the online medical appointment service in Russia.
