Abstract

General Background: Cyberattacks targeting critical digital infrastructure pose significant threats to national security, public services, and digital sovereignty. Specific Background: The June 2024 Brain Cipher ransomware attack on Indonesia’s National Data Center (PDNS 2) in Surabaya, executed using a LockBit 3.0 variant, disrupted over 200 public services and exposed systemic vulnerabilities. Knowledge Gap: Despite the scale of the incident, there is limited integrated analysis combining technical reconstruction, impact assessment, and strategic cybersecurity lessons from this attack. Aims: This study aims to provide a comprehensive technical analysis, evaluate the impact, and derive national cybersecurity lessons from the Brain Cipher ransomware incident. Results: Using a qualitative case study with a Digital Forensics Review (DFR) approach, the analysis confirms that 282 government institutions were affected, disrupting essential services such as immigration and taxation. The attack exploited remote access points for data encryption, while emergency recovery relied on AWS migration and Batam-based backups, revealing external dependencies. Novelty: This study offers an integrated examination of a large-scale ransomware incident by combining forensic reconstruction, impact evaluation, and policy-oriented cybersecurity insights. Implications: The findings emphasize the need for geographically redundant infrastructure, automated failover testing, behavior-based detection systems (EDR/XDR), and the institutionalization of security culture to strengthen national cyber resilience and safeguard digital sovereignty.
