What is this Korean spider and is it poisonous?

If you have ever been in the military and stationed in Korea, it seems that there is this one species of spider which spins webs all over base, have an average body size of a thumb, and are cannibalistic. They are bright yellow with long black blotches, and I have no idea what they are called either in Korean or in English. It seems more numerous than any other insect in Korea, but perhaps that is because they are so visible. Anyone know what it could be and if it is poisonous?
