Brinztech Alert: Database of Pemerintah Kota Surabaya is on Sale

Dark Web News Analysis: Alleged Database of Pemerintah Kota Surabaya is on Sale

A dark web listing has been identified, advertising the alleged sale of a database belonging to the Pemerintah Kota Surabaya (Surabaya City Government). The threat actor claims the data includes personal information of government officials, such as names, job titles, office addresses, and telephone numbers.

This incident, if confirmed, represents a critical security failure for a government body. The exposure of sensitive data from government officials is not just a privacy violation; it is a direct threat to the integrity of public services and the security of internal government systems. The breach, if legitimate, comes against the backdrop of a major ransomware attack on Indonesia’s National Data Center in Surabaya in June 2024, raising concerns about persistent vulnerabilities in the city’s digital infrastructure.

Key Insights into the Surabaya City Government Compromise

This alleged data leak carries several critical implications:

• High-Value Data for Spear-Phishing: The leaked data provides a perfect blueprint for highly sophisticated spear-phishing attacks and social engineering campaigns. Attackers can use the names, job titles, and contact information of government officials to impersonate them, tricking colleagues or subordinates into revealing sensitive credentials, installing malware, or providing a path to more critical internal systems.
• Violation of Indonesia’s UU PDP: As a government entity, the Pemerintah Kota Surabaya is subject to Indonesia’s new Personal Data Protection Law (UU PDP) No. 27 of 2022. This law mandates that government bodies, as data controllers, must implement robust security measures and, in the event of a breach, notify the national data protection authority and affected individuals within 3×24 hours of discovery. Failure to do so can result in severe legal and administrative penalties.
• Threat to Critical Infrastructure: The compromise of government officials’ data can be a precursor to a more significant attack on critical infrastructure. With a detailed understanding of the organization’s structure and key personnel, a threat actor can launch a targeted attack that could disrupt essential public services, such as water, power, or transportation, causing a major impact on the public interest.
• Reputational Damage and Erosion of Trust: A confirmed data breach of this nature could severely damage the reputation of the Surabaya City Government and erode public trust in its ability to protect sensitive citizen data. Given the recent history of cyberattacks on national and local government systems, this incident could exacerbate public concerns about Indonesia’s overall cybersecurity posture.

Critical Mitigation Strategies for the Surabaya City Government and Authorities

In response to this alleged incident, immediate and robust mitigation efforts are essential:

• Urgent Investigation and Regulatory Notification: The Surabaya City Government must immediately launch a forensic investigation to verify the authenticity of the dark web claim and assess the full scope of the compromise. It is critical to notify both the Ministry of Communication and Informatics (Kominfo) and the National Cyber and Crypto Agency (BSSN) within the required timeframe as per the UU PDP.
• Enhanced Phishing Awareness Training: The government must conduct a comprehensive security awareness training program for all employees, with a focus on recognizing and reporting sophisticated spear-phishing and social engineering attacks that may leverage the leaked PII.
• Review and Strengthen Access Controls: The government must conduct a full review of all access controls, authentication mechanisms, and privileged accounts. The use of Multi-Factor Authentication (MFA) should be enforced on all critical systems to prevent unauthorized access, even if a threat actor has stolen credentials.
• Proactive Monitoring and Threat Intelligence: The government must implement proactive monitoring to identify any further exposure of sensitive information related to the Pemerintah Kota Surabaya on dark web forums and other online sources. This will help them to quickly identify and respond to any signs of a breach.
