Authorities are hunting down a hacker who has threatened to release the personal data of 55 million Thais if the government agency allegedly involved in the leakage of information fails to meet a ransom demand by April 5.

Pol Lt Gen Worawat Watnakhonbancha, commissioner of the Cyber Crime Investigation Bureau (CCIB), said that the CCIB has asked the Ministry of Digital Economy and Society (DES) as well as the National Cyber Security Agency (NCSA) to look into the case and find out whether the personal data was hacked or leaked by certain officials.
