Jung Kook has once again become linked to a massive cybercrime case after South Korean authorities confirmed the extradition of a suspected hacking mastermind accused of stealing billions of won in assets from celebrities and high-profile individuals.
According to South Korea’s Ministry of Justice and National Police Agency, a 40-year-old Chinese national identified only as “A” was extradited from Thailand to South Korea on May 13.
Authorities say the suspect allegedly led an international hacking organization that operated across multiple countries, including Thailand, and targeted financial accounts using illegally obtained personal information.
The case is being handled by the cyber investigation unit of the Seoul Metropolitan Police Agency.
Investigators claim the hacking group illegally accessed systems connected to low-cost mobile service providers and other online platforms between August 2023 and April 2025. Using stolen personal data, the group allegedly carried out unauthorized financial withdrawals and attempted large-scale asset theft.
Among the reported victims was Jung Kook of BTS.
Authorities stated that HYBE shares worth approximately 8.4 billion Korean won connected to Jung Kook were targeted during the operation. However, officials say the full financial damage was ultimately prevented after HYBE suspended the suspicious transactions.
The overall criminal operation is believed to involve attempted theft and embezzlement totaling around 38 billion Korean won.
Investigators also revealed that other victims allegedly included: conglomerate executives, legal professionals, wealthy individuals, and other high-profile public figures.
This is not the first major arrest connected to the case.
Last year, South Korean authorities arrested another alleged mastermind, identified as “B,” along with 16 domestic and international members connected to the hacking organization. B was extradited in August 2025, formally indicted the following month, and is currently standing trial while in detention.
South Korea reportedly began coordinating with Thai authorities in May last year through an emergency arrest request before filing formal extradition procedures in August.
Officials emphasized that the case carries major social significance due to both the scale of the alleged cybercrime and the prominence of several victims involved.
A representative from the Seoul Metropolitan Police Agency stated:
“As this case has significant social impact, we will conduct a rigorous investigation.”
Authorities are now expected to request a formal detention warrant after completing interrogations and analyzing materials seized during the extradition process.
The case has already triggered strong reactions online, particularly among fans of BTS, many of whom expressed shock over the scale of the alleged hacking operation and relief that the attempted theft involving Jung Kook was reportedly blocked before major financial losses occurred.
