MGTS

In 2002 a significant data breach involving the Moscow City Telephone Network MGTS was identified. The incident involved the unauthorized collection and distribution of a database containing personal records of approximately 4 million subscribers in Moscow. The leaked data set included highly sensitive information such as full names residential addresses telephone numbers and passport details. This event became one of the earliest high profile examples of large scale personal data exposure in the Russian telecommunications sector highlighting vulnerabilities in digital record keeping during that era.
