This study overviews over 70 affiliations of the occupied territories of Ukraine to the Russian Federation in the inspireHEP database and traces their origin to the impostor institutes created by the Russian Federation on the occupied territories of Ukraine. Their scientific papers are published by the international publishers (IOP Publishing, Oxford University Press, Springer, edpScience, WorldScientific, MDPI, PoS/SISSA, Elsevier, IEEE, etc.) or databases (arXiv), allowing Russian state propaganda to spread within the international scientific community.
