Subdomain Data of Polrestabes Surabaya are Leaked

Dark Web News Analysis: Polrestabes Surabaya Subdomain Data Leak

A dark web listing has been identified, advertising the alleged data leak of subdomains associated with Polrestabes Surabaya (Surabaya City Police). The leaked data includes a list of subdomains, corresponding IP addresses, and Cloudflare status. The subdomains listed—including autodiscover, cpanel, webdisk, and webmail—are not just a simple data dump; they are a detailed roadmap of the organization’s digital infrastructure.

This incident is particularly severe as it targets a law enforcement agency. The compromise of infrastructure data, if legitimate, provides malicious actors with a significant reconnaissance advantage. This information can be used to bypass security measures, discover vulnerabilities in exposed services like webmail and cPanel, and launch highly sophisticated and targeted attacks on the police force and the public. This alleged breach comes in the wake of a major ransomware attack on Indonesia’s National Data Center in Surabaya in June 2024, highlighting a persistent and alarming trend of cyberattacks targeting the city’s government infrastructure.

Key Insights into the Polrestabes Surabaya Compromise

This alleged data leak carries several critical implications:

• High Risk of Phishing and Spoofing: The exposure of subdomains, especially webmail and mail, provides attackers with the necessary information to craft convincing phishing campaigns. Threat actors can use this data to impersonate official police communications, tricking officers or the public into revealing login credentials or other sensitive information, which can then be used to compromise more critical systems.
• Exposure of Internal Infrastructure: The leak of subdomains like cpanel and webdisk is a major security risk. cPanel is a web hosting control panel, and webdisk is a file management tool. The disclosure of these services reveals potential entry points into the police force’s internal systems. An attacker can use this information to launch brute-force attacks or exploit unpatched vulnerabilities in these services to gain unauthorized access to servers and sensitive data.
• Violation of Indonesia’s UU PDP: As a government entity, Polrestabes 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 comply can result in severe legal and administrative penalties.
• National Security Implications: A breach of a police force’s infrastructure data can have national security implications. This information could be used by state-sponsored actors or organized crime rings to launch cyberattacks that disrupt police operations, interfere with criminal investigations, or compromise the privacy of law enforcement personnel.

Critical Mitigation Strategies for the Polrestabes Surabaya and Authorities

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

• Urgent Investigation and Regulatory Notification: Polrestabes Surabaya 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.
• Audit and Harden Exposed Services: All exposed services identified in the leaked data, including cpanel, webmail, and webdisk, must be immediately audited and hardened. This includes patching all known vulnerabilities, disabling any unnecessary services, and implementing a strict access control policy to prevent unauthorized access.
• Enhance Phishing Awareness Training: The police force must conduct a comprehensive security awareness training program for all personnel, with a focus on recognizing and reporting sophisticated phishing attacks and social engineering campaigns that may leverage the leaked subdomain data.
• Implement Proactive Domain Monitoring: The organization should implement domain monitoring tools to identify and quickly takedown any fraudulent domains or subdomains that may be registered to impersonate the police force. This will help them to prevent spoofing attempts and protect the public from scams.
