The report, produced by the Russian SVR and obtained by a European intelligence agency, describes a fake assassination attempt on Orbán as a way to shift the election campaign's focus entirely to issues such as security and stability.
It is unclear whether the report has been presented to higher-level officials in Moscow. "This is another example of disinformation," Kremlin spokesman Dmitry Peskov said in response to questions from The Washington Post about the document.
Orbán's nationalist right-wing party Fidesz is facing Péter Magyar's social-conservative Tisza in elections on April 12.
