A Russian national, identified as Denis Obrezko, has pleaded not guilty to charges of participating in a broad cyber espionage campaign. Obrezko, formerly associated with Russia's FSB intelligence agency, was extradited from Thailand to the U.S. to face these allegations.

Obrezko, who also worked for the technology firm Yutek-NN, faces a maximum of 10 years in prison if convicted. His defense attorney stated they will contest the charges vigorously on both factual and legal grounds. The indictment details the use of various tools to extract data from victim systems.
