South Korea's JoongAng Daily reports that the Seoul Metropolitan Police Agency recently uncovered an attempt by North Korea to launch cyber attacks on Incheon International Airport using malware in gaming apps.

"A 39-year-old South Korean game distributor was arrested on Sunday for involvement and charged with violating the National Security Law," the article states. "The National Intelligence Service helped arrest him, police said. According to the police, the South Korean man, identified by the surname Jo, traveled to Shenyang, northeastern China, starting in September 2009 and met agents of an alleged North Korean trading company. He allegedly asked them to develop game software to be used in the South."

The police say Jo bought gaming software from the agents for tens of millions of Korean won, knowing both that they were agents from North Korea's Reconnaissance General Bureau and that the software was infected with malware.

"The games were then sold by the man to online gaming services in South Korea, allowing the malware to be covertly installed on end-user systems," writes's Shaun Nichols. "Infected systems were then ordered by a command server to attack the airport in an effort to disrupt flight traffic. Police are also investigating whether the malware also harvested user details from the infected machines."
