In 2009, police discovered that Jun's cell phone had been illegally cloned. Seoul Metropolitan Police arrested a private detective identified as Kim, who testified that it was ordered by SidusHQ (Jun's then-agency of 13 years), for which he was paid ₩6.4 million in cash by the brother of CEO Jung Hoon-tak. Police believed Jun’s management company used the cloned phone to keep tabs on her, in an attempt to exert control over all aspects of her life. SidusHQ denied those allegations. Jung Hoon-tak was later cleared after police could not find any concrete evidence of his direct involvement. Kim was sentenced to one year in prison for invasion of privacy, Jung's brother received suspended jail terms. Because of the scandal, many expected her to leave once her contract expired, but she surprisingly extended her contract with SidusHQ for one more year. Then in 2011 she set up her own management agency J&Co. Entertainment, which was later renamed to Culture Depot.
