The Wall Street Journal tracked the most disruptive attacks to one group: a notorious gang of Eastern European cybercriminals once called the “Business Club,” with ties to Russian government security services, according to threat analysts and former law-enforcement officials who closely follow Eastern European cybercrime operations.
