Its principles Kazakhstan have arrested a Russian cybersecurity expert wanted by the United States, his employer said today, and authorities in Moscow said they would also seek his extradition.

Nikita Kislichin, an employee at the Russian cybersecurity company FACCT, was arrested on June 22 and Kazakh authorities are considering Washington’s request for his extradition, the company said in a statement.

The company also said the charges against Kislitsin, who did not flee abroad, date back to his time as a journalist and independent researcher. However, he did not provide further details.

Reuters was unable to contact Kislitsin or his representatives.

Today FACCT reported that it has been informed that Kislichin, former editor of Hacker magazine, is also wanted by Russia.

Separately, the Russian newspaper Vedomosti wrote that a Moscow court had ordered Kislichin’s arrest in absentia on charges of unauthorized access to digital information and that Russia would seek his extradition.

Russia’s state news agency RIA reported that the Russian consulate in Kazakhstan had asked Astana not to rush Kislichin’s extradition to the United States.

FACCT was spun off from Singapore-based cybersecurity firm Group-IB, which said today it was not involved in any way in the investigation.

Police in Kazakhstan, where today is a public holiday, could not be reached for comment.
