SEOUL, March 4 (Xinhua) -- A fresh wave of cyber attacks hit major South 
Korean Web sites, including that of the presidential office Cheong Wa 
Dae, on Friday, local media reported, citing industrial sources.

Starting 10 a.m. Friday, 40 web sites, including the ones of 
presidential office Cheong Wa Dae, the Ministry of Foreign Affairs and 
Trade and top lender Kookmin Bank, came under distributed 
denial-of-service (DDoS) attacks, Yonhap News Agency reported, citing 
AhnLab, South Korea's top information security company.

Additional attacks are expected to come at 6:30 p.m., Yonhap said.

DDoS attacks are unsophisticated but pose great difficulties for 
websites to defend against. The attacker directs a giant traffic surge 
to its target, overwhelming the site's servers and making it hard for 
legitimate users to access the site.
