Brinztech Alert: Alleged Database of SI-JABAT Kaltim Leaked on Dark Web

Dark Web News Analysis

Cybersecurity intelligence from February 27, 2026, has identified a high-priority listing involving the SI-JABAT (Sistem Informasi Jabatan) portal for the Provincial Government of East Kalimantan (Kaltim). This platform is the primary digital registry for government positions and civil servant career tracking in the region.

The threat actor claims to have exfiltrated a structured database directly from the government sub-domain. In a highly aggressive post, the attacker criticized the “admin developers,” suggesting that the breach was facilitated by basic security oversights or unpatched vulnerabilities. The exfiltrated data reportedly includes:

• Government Identifiers: NIP (Nomor Induk Pegawai)—the unique National Employee Identification Number for Indonesian civil servants.
• Personally Identifiable Information (PII): Full names and residential/work contact markers.
• Professional Metadata: Specific positions (jabatan), job types, and work units (unit kerja) within the Kaltim provincial administration.
• Escalation Warning: The attacker claims to possess a larger volume of data and is currently “organizing” it for wider public distribution.

Key Cybersecurity Insights

The breach of a provincial government personnel system represents a “Tier 1” threat due to the potential for targeted social engineering and institutional disruption:

• High-Context “Government” Phishing: This is the most immediate risk. Armed with NIP numbers and specific job units, scammers can launch lures that are indistinguishable from official internal communications. Employees are highly likely to trust a notification regarding “mandatory training” or “salary adjustments” if it identifies their exact bureaucratic role.
• Identity Theft and Account Takeover (ATO): In Indonesia, the NIP is a key identifier often used as a username or “security check” for various government portals and regional banking services. Attackers assume that employees may reuse passwords across the SI-JABAT portal and their personal emails. If this leak contains password hashes, malicious actors will use them to hijack more sensitive digital assets.
• Espionage and Administrative Mapping: The exposure of the entire organizational structure (work units and positions) allows adversarial groups to map the internal workings of the East Kalimantan government. This intelligence can be used to identify key decision-makers or vulnerable administrative links for future cyber-espionage or extortion.
• Regulatory Scrutiny (UU PDP No. 27/2022): Under Indonesia’s Personal Data Protection (PDP) Law, government agencies are treated as data controllers with strict obligations to secure citizen and employee data. This breach could trigger an investigation by BSSN (National Cyber and Crypto Agency) and Kominfo, leading to mandatory security audits and institutional penalties.

Mitigation Strategies

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

• Immediate Force-Reset for All ASN Credentials: The East Kalimantan Provincial Government must mandate a Force-Reset for every account associated with the SI-JABAT portal. Employees should be instructed to use unique, complex passphrases and never reuse them for personal banking.
• Enforce App-Based Multi-Factor Authentication (MFA): Move beyond password-only security. Implement App-Based MFA for all administrative and personnel portals to ensure that even if an attacker has a leaked NIP, they cannot gain unauthorized access.
• Zero Trust for “Internal” Communications: Civil servants in Kaltim should treat any unsolicited digital message—even those appearing to come from “BKD” (Regional Personnel Agency)—asking for “verification” or “file updates” with extreme caution. Always verify such requests through an official, offline channel.
• Audit for Admin Panel Vulnerabilities: The technical team must conduct an emergency Vulnerability Assessment of the kaltimprov.go.id sub-domains. Focus on fixing “Insecure Direct Object Reference” (IDOR) flaws or SQL injection points that likely allowed the database scraping.
