1.2 Million NIKs of Poor Residents Stolen, Central Java Diskomdigi Requests BSSN Assistance

The Head of the Communication, Informatics and Digital Service (Diskomdigi) of Central Java Province, Lilik Henry Ristanto, revealed that his office has requested assistance from the National Cyber and Crypto Agency (BSSN) to handle the hacking and theft of 1.2 million National Identity Numbers (NIK) belonging to residents classified as poor in Central Java. He stated that BSSN has already commenced handling the incident. “On 25 February, five days after the notification, the Head of the Central Java Diskomdigi, as Chair of the Computer Security Incident Response Team (CSIRT), sent a letter to the Head of BSSN RI requesting post-incident assistance, and this has been handled by BSSN up to the present,” he said during an interview in Semarang City on Thursday (16/7/2026). Lilik disclosed that his office received notification from BSSN regarding indications of a data leak on 20 February 2026. According to Lilik, upon receiving the information about the data leak from BSSN, Central Java Diskomdigi immediately took follow-up measures within the limits of its authority. He mentioned that the primary step taken was conducting an assessment of the system. “Our colleagues from the cryptography and cyber security division carried out a self-assessment, then deemed it necessary, as the risk mitigation would have a greater impact and require substantial resources, to send the letter on 25 February as our effort to minimise the risk of further leaks,” Lilik said, referring to the dispatch of the request for assistance to BSSN. He explained that the target of the hacking was the Central Java Integrated Data (DT) application. The application can also be accessed via a website. According to Lilik, the application is managed by the Central Java Social Service (Dinsos).
