Former world number one Lee Chong Wei did his part by winning the men's singles match against Son Wan Ho, but ultimately the Korean players proved to be stronger than their Malaysian counterparts on the day.
The men's doubles pair of Lee Yong Dae-Yoo Yeon Seong opened Korea's account when they beat Goh V Shem-Tan Wee Kiong 21-18 21-16 in an eagerly contested match that lasted 48 minutes.
The score was 2-1 after the women's singles match in which Sung Ji Hyun outclassed Tee Jing Yi 21-17 21-12, before Lee pulled one back for Malaysia.
The two-time Olympic silver medalist needed only 42 meates to overcome San 21-17 21-12.
Korea sealed the tie, though, after winning a gruelling women's doubles match, as Chang Ye Na-Jung Kyung Eun beat Vivian Kah Mun Hoo-Woon Khe Wei 21-23 21-16 21-11 after spending 69 minutes on court.
Despite the country's defeat, Lee was satisfied with how he performed in his first major competition since returning to the fray, having spent the previous eight months suspended due to contravening doping legislation.
"I feel that I performed pretty well, I was satisfied," the former world number one told reporters after the tie.
