Ulyanovsk FOMS 2018

In 2018 a significant data breach occurred involving the Compulsory Medical Insurance Fund of the Ulyanovsk region in Russia. The incident resulted in the exposure of sensitive personal information belonging to over 800 thousand citizens. The leaked dataset included full names, contact phone numbers, physical addresses, and passport details. This leak is particularly concerning due to the combination of identity information and healthcare affiliation which poses a high risk for identity theft and social engineering attacks against the affected population.
