It depends. One possible way is to request FSB to investigate based on presented evidence (illegal supplies of military equipment are their scope of responsibility and we do know that these supplies were not authorized in accordance to Russian laws). If they will not start investigation, then report to the Office of Russian Prosecutor's General. If prosecutors reject the case, go to local court and then up to the Supreme Court. If no success there, go to the European Court of Human Rights and sue Russian Federation. If Russia loses in ECHR, Ministry of Finances will be responsible for paying damages. If (very unlikely, but possible) FSB agrees to investigate and finds the responsible people, likely, it will also find that they were on duty when supplies of equipment took place and, thus, Ministry of Finances of Russian Federation will be responsible for paying damages.
