About 40 web sites were targeted, including the presidential office, the National Intelligence Service, the Ministry of Foreign Affairs and Trade, Kookmin Bank, the defense ministry, and the US military in Seoul, according to BusinessWeek. The government issued its third-highest alert against online attacks.
"DDoS(Distributed Denial of Service) attack is now on Korean websites including government webpages," AhnLab said in a statement. "We're on emergency response with our all resources including ASEC and CERT, providing emergency antivirus solution. Additional DDoS attack occurred around 18:30 (Korean Time), not scored though. It just caused insignificant damages as users install antivirus and emergency solution from AV vendors, such as AhnLab, and other government organizations."
