Sergei Anatolyevich Filimonov, 36, a Russian national and web developer who was allegedly involved in a transnational cyber‑fraud conspiracy responsible for large‑scale bank account takeover activity, was arraigned Friday in the Northern District of Georgia after being extradited from the Republic of Georgia.
