Who leaked KGF 2 bytes before the teaser release?

KGF 2 Teaser, KGF 2 Movie

KGF Chapter 2 teaser was expected to be released on the same day as its lead actor Yash’s birthday, i.e. The 8th of January. However, the scheme had been destroyed by an intruder leaked out of the teaser long before the date suggested. In order to contain the impact, the film team had no choice but to propose its teaser to release, thus releasing it on January 7 instead.
