Brinztech Alert: Sensitive Database of KPU Kota Tegal Allegedly Leaked

Dark Web News Analysis

Cybersecurity intelligence from February 21, 2026, has identified a high-priority post on a prominent hacker forum involving the KPU Kota Tegal (General Election Commission of Tegal City). The threat actor, “MR-Zeeone-Grayhat,” has released a database purportedly for free, containing the sensitive personal records of thousands of citizens.

The leak is particularly alarming due to the depth of the “Identity Fragments” provided. The exfiltrated information reportedly includes:

• Government Identifiers: Full NIK (National Identification Number) and NO KK (Family Card Number).
• Personally Identifiable Information (PII): Full names, places and dates of birth, and gender.
• Geographic Data: Precise residential addresses, including sub-districts (Kecamatan) and villages/wards (Kelurahan).
• Scale: The database appears to be a comprehensive voter list for the Tegal City region.

Key Cybersecurity Insights

The breach of a city-level election commission represents a “Tier 1” threat with severe implications for Indonesian civil security:

• Complete Identity Cloning Kit: The combination of NIK and NO KK is the “gold standard” for identity verification in Indonesia. With these two numbers, malicious actors can perform high-stakes identity theft, including taking out fraudulent loans, hijacking e-wallets, or opening unverified bank accounts.
• Hyper-Targeted “Voter” Social Engineering: Armed with precise addresses and birth dates, scammers can launch hyper-convincing Smishing (SMS phishing) lures. Residents are significantly more likely to trust a message regarding “social assistance” or “election venue changes” if the message correctly identifies their family card details and ward.
• Electoral Integrity & Trust Erosion: Beyond individual theft, these leaks are weaponized to undermine faith in the democratic process. Even if the voting systems themselves are secure, the perception that citizen data is “up for grabs” erodes the legitimacy of the commission.
• PDP Law Compliance Risk: This incident falls under the Indonesian Personal Data Protection (PDP) Law. The KPU Kota Tegal faces intense scrutiny from the BSSN (National Cyber and Crypto Agency) and potentially massive administrative consequences for failing to secure “Sovereign Citizen Data.”

Mitigation Strategies

To protect your digital identity and ensure regional administrative resilience following this exposure, the following strategies are urgently recommended:

• Immediate Monitoring of NIK/KK Linked Services: Residents of Tegal City should immediately check their Dukcapil status and monitor their financial apps (GoPay, OVO, Dana) for unauthorized login attempts. If you notice any suspicious activity, report it to the authorities and the relevant service provider instantly.
• Enforce Multi-Factor Authentication (MFA): Move beyond password-only security. Always use App-Based MFA or biometric verification for any platform that handles your national ID data to ensure that even if an attacker has your leaked NIK, they cannot access your accounts.
• Heightened Vigilance Against “Official” Lures: Be extremely skeptical of unsolicited WhatsApp messages or calls regarding “Election Updates” or “Bansos” (Social Aid) that require you to click a link. KPU will never ask for your password or sensitive verification codes via an unverified link.
• Comprehensive System Hardening & DLP: KPU Kota Tegal must implement robust Data Loss Prevention (DLP) measures to detect and block the movement of large databases. Conduct a thorough Forensic Analysis to identify the exfiltration vector—likely a vulnerable API or an unpatched server.
