Undora.ru

Undora is a prominent sanatorium located in the Ulyanovsk region of Russia. In February 2020 the website suffered a cyber attack targeting the callback request system. Unauthorized access allowed attackers to extract personal information submitted by potential clients through online forms. The incident specifically impacted the database of individuals who requested call returns or consultations regarding medical and recreational services. The breach resulted in the exposure of thousands of records containing contact details and inquiry metadata. This event highlights vulnerabilities in small scale medical tourism web platforms and the risks associated with unsecured callback integration tools.
