Olga Sivushkova (Pshenichnikova)

Pshenichnikova is a transgender person, originally from Tajikistan. She served in the Israel Defense Forces prior to her transition, then in 2012 declared that she wanted to renounce her Israeli citizenship and "become part of the Palestinian resistance" and moved to the Deheishe refugee camp in the West Bank. The Times of Israel wrote that West Bank residents said Andrei Pshenichnikov was "posing as a Russian activist" and "was suspicious"; Palestinian authorities had twice handed him over to Israeli authorities. In late 2012, Pshenichnikova was arrested in Egypt, where Pshenichnikova was sentenced to two years in prison for filming security installations in Sinai.

According to her testimony in court, she was a secret FSB agent in the case against "New Greatness" organization. Pshenichnikova said she began co-operating with the authorities after she left a chat room with the defendants in the case because of insults directed at her. "My assignment was to identify [one of the defendants in the case] Anna Pavlikova, to describe her appearance. The truth is that the New Greatness organisation supported the violent overthrow of the government," she said at the trial.

In an interview with Dozhd in 2018, Pshenichnikova said she was an admirer of Vyacheslav Maltsev, while at the same time supporting Vladimir Putin and being a member of the National Liberation Movement (NLM).

In January 2025, Pshenichnikova was detained in Vologda. A case of public justification of terrorism was opened against her because of reposts of materials of the Russian Freedom Legion. According to other information, she corresponded with representatives of the Russian Freedom Legion, who prepared her to carry out a series of terrorist attacks on the territory of the Russian Federation.

During the search in the flat they found a pistol similar to a traumatic pistol and an Israeli passport in Andrei's name obtained before the change of the gender marker.

On 12 May 2025, Pshenichnikova was sentenced to four years' imprisonment in a general regime penal colony.
