A significant data breach at the Russian VPN service SplitVPN, previously operating under the name NotVPN, has exposed the personal information of approximately 865,000 users.
The incident took place in July 2026 and involved the theft of a 17 GB SQL database that was subsequently shared on a cybercrime forum. The compromised dataset contained emails, IP addresses, geolocation details, and partial payment card information.
Analysis of the leaked material revealed 23.4 million user records, 13.6 million device entries, and 2.6 million payment transactions. The database also included nearly 58 million connection logs covering the period from June 2025 to 21 July 2026, documenting which device connected to which VPN server and the exact timestamps of those connections.
Although the logs do not record visited websites, the metadata can still link user accounts, devices, IP addresses, and specific servers. This level of detail directly contradicts SplitVPN’s earlier public claims that it maintained no connection or activity logs.
The exposure is especially sensitive for individuals who used the service to bypass government censorship and surveillance, as the retained metadata could potentially be used to identify and track such users.
