Mos.ru

A major data incident involving the Moscow government portal Mos.ru occurred when a large database containing personal information of millions of users was exposed. The breach reportedly originated from a vulnerability in the systems of a third party contractor or through unauthorized access to an API. The leaked records include sensitive personal identifiers and contact details of citizens who use the platform for municipal services. Security researchers identified the data circulating on various underground forums which posed significant risks for phishing and identity theft targeting Russian residents.
