Specifically, Distributed Denial of Secrets says the data comes from the Roskomnadzor of the Republic of Bashkortostan. The Republic of Bashkortostan is in the west of the country.

Motherboard found references to the Republic of Bashkortostan in some of the released files.

“Appears genuine but I cannot vouch all of them of course,” Andrei Soldatov, a Russian journalist who has extensively covered Russia’s censorship apparatus, told Motherboard in an online message after reviewing a small subsection of the files. “Right now I don’t see anything really surprising.”

“We will soon be releasing the raw data while we look for solutions to extracting the data. One appears to be a legal research database that was, according to the file timestamp, last modified in 2020. The other appears to be a database for HR procedures,” Distributed Denial of Secrets wrote on its website.

The source, a part of Anonymous, urgently felt the Russian people should have access to information about their government. They also expressed their opposition to the Russian people being cut off from independent media and the outside world. We are publishing this release in anticipation of Russia potentially being cut off from the global internet on March 11, and hope Russians will have time to download this data, before then.

Over 360,000 files from the Russian Federal Service for Supervision of Communications, Information Technology and Mass Media (previously the Russian Federal Surveillance Service for Compliance with the Legislation in Mass Media and Cultural Heritage Protection), often abbreviated and referred to as Роскомнадзор or Roskomnadzor. Roskomnadzor is the Russian agency responsible for monitoring, controlling and censoring Russian mass media as well as compliance with personal data processing requirements and coordinating activities involving radio frequencies.

Roskomnadzor's activities are always a matter of public interest to the people of Russia and to the world. Their recent actions have only emphasized this:

Roskomnadzor has given instructions about what can be said and ordered media outlets to delete stories that call Russia's invasion of Ukraine an Invasion. In response to Facebook's fact-checking Russia's statements about the war, Roskomnadzor began restricting access to Facebook before later blocking it. Roskomnadzor also threatened to block access to Russian Wikipedia over their article about the Russian invasion of Ukraine. This follows an established history of similar actions in the past.

These files come from the Roskomnadzor of the Republic of Bashkortostan, one of the largest republics of Russia. While some of the material will be Federal, much of it will relate to Bashkortostan but all of it offers an unprecedented look at Roskomnadzor.
