The Ukrainian government’s military intelligence service claimed to have compromised the central servers of the Russian Federal Taxation Service (FNS) and over 2300 regional servers.
The military intelligence service said that the hack was the result of a successful special operation on the territory of Russia.
The cyber units of the Main Intelligence Directorate of the Ministry of Defense of Ukraine infected thousands of servers of the Russian tax service with malware and wiped the databases and backups.
According to a statement published by the Main Intelligence Directorate of the Ministry of Defense of Ukraine (GUR), the Ukraine cyber units broke into one of the “key well-protected central servers” of the tax service as well as more than 2,300 regional servers throughout Russia and occupied Crimea.
The hackers also hit a Russian IT company Office.ed-it.ru, that operates the database of Russian Federal Taxation Service (FNS).
The military intelligence was also able to capture internet traffic of tax data for the whole of Russia.
For four consecutive days, the experts at the Russian agency attempted to restore the service without success. Ukraine intelligence believes that the Federal Tax Service of the Russian Federation will remain paralyzed for at least a month. They believe that the complete recovery of the tax system is impossible.
The impact of cyberattacks denotes Ukraine’s increased cyber warfare efforts against Russia, leveraging its military intelligence cyber units to disrupt critical Russian infrastructure.
