Shevchenko said she had been approached repeatedly by people she believed to be from the Russian government. She insisted, however, that she had always rejected the advances. She said she had not been threatened or intimidated as a result.
A 2014 profile of Shevchenko in Russian Forbes magazine noted that she worked with DialogNauka, a Russian company that listed among its clients the Russian ministry of defence and parts of the security services. Questioned by the Guardian, she insisted that none of her own work for DialogNauka “was even remotely possible to use as a nation-state attacks supply”.
