Huge European telecom leak exposes Swedbank, SEB, airBaltic and dozens of other companies’ clients

The Latvian branch of CSCTelecom, a telecommunications provider, left a database containing over 125 million SMS messages exposed. The leaked records span from October 2022 to September 2026 and were updated in real time, meaning attackers could have intercepted authentication codes, password reset links, and private information before the recipients even saw them.
Our research team discovered the exposed CSCTelecom ClickHouse database on September 28th, 2026. At the time, the service had sent over 3 million SMS messages in September alone.
The database included messages from major banks, medical institutions, popular shopping sites, government organizations, and even Latvia's national emergency hotline, 112. While CSCTelecom operates primarily in Latvia, the leak also affected businesses and individuals in Lithuania and Estonia.
