It seems boy group B.I.G (Boys In Groove)'s official Twitter account was hacked this past August 3.
The Twitter account posted an official notice, which reads,
"Hello, this is GH Entertainment. This past early morning (August 3 KST), B.I.G's official Twitter was hacked, resulting in a post which might have caused you all concern, and we offer our apologies for worrying you. Currently, we are in the process of taking care of the situation, and we will do our best so that an occurrence like this does not happen again."
Hopefully, the hacker will be caught.

지난밤 새벽에 B.I.G의 공식 트위터가 해킹을 당해 팬 여러분들께 혼란이 될 게시물이 올라가 심려끼쳐 드려 죄송합니다. 현재 정리 중에 있으며, 다시는 이런 일이 발생하지 않도록 하겠습니다.
