Personal data for over a million Russian nationals has reportedly been leaked. The data allegedly belongs to some of the citizens who participated in the recent blockchain-based e-vote on Constitutional amendments. According to an investigation published by Russian language media outlet Meduza, an archive titled “degvoter.zip”, which contains said data, was publicly available for download for at least several hours on July 1 via a government website. The file has since been distributed through various Telegram groups and channels.

The archive was password protected. According to the publication, however, it could be easily hacked with a free password cracking tool. Along with the archive, there was an unpassword protected database titled “db.sqlite”. This database allegedly contained passport numbers for over a million voters from Moscow and Nizhniy Novgorod — two cities in Russia where residents could cast their votes online. The system that allowed for online voting was based on the Exonum blockchain platform developed by Bitfury.
