As "Dozhd" clarifies, the declarations have not been deleted from the FSB server, which means that they are still available for download via direct links.
It is indicated that the department took advantage of the recently adopted law and hid the declarations, and the new ones "do not plan to publish yet".
Recall that in early April, Russian President Vladimir Putin signed amendments to the law on state protection, which allows agencies to classify data on the property of security officials involved in special operations and the fight against terrorism. After the law was passed, the data on the incomes of the Deputy Defense Minister Sergei Shoigu were hidden.
