After losing their Instagram account to a hacker on the 7th of January and the account being sold on the 8th, 24K regained control of their account on the 11th as announced by the group's agency, Choeun Entertainment, through their official social mediaaccounts. They revealed that they are still working on restoring the posts, which were deleted by the hacker.
They also announced the launch of the 'Instagram Comeback Account'. Since many people unfollowed the group account during the hack to not give attention to the hacker, 24K lost around 15K followers. This event asks people to re-follow the Instagram account between the 12th and 15th of January. Those who do can win unreleased photos from the members. A total of three people will be picked.
