Brinztech Alert: The Alleged Database of Proliga is Leaked

Dark Web News Analysis

The dark web news reports a data breach involving Proliga, the top-tier professional volleyball league in Indonesia (organized by PBVSI). A threat actor on a hacker forum is claiming to have leaked a database belonging to the league’s digital infrastructure, likely related to its ticketing or fan engagement platform.

While the exact volume is currently under analysis, sports league breaches typically compromise sensitive fan data. The alleged dataset reportedly includes Full Names, Email Addresses, Phone Numbers, Ticket Purchase Histories, and potentially NIK (National ID Numbers) if identity verification was required for ticket bookings.

Key Cybersecurity Insights

Breaches in the sports and entertainment sector create high-volume fraud opportunities, particularly during active seasons:

• Ticket Scalping & Fraud: The most immediate risk is Ticket Scams. Attackers can use the Purchase History to identify active fans and send phishing emails claiming: “Your ticket for the Grand Final has been cancelled due to payment error. Click here to repurchase.” Alternatively, they can use the data to create fake tickets or scalp valid ones if access codes were exposed.
• Identity Theft (NIK): If the database includes NIK (Nomor Induk Kependudukan), the risk escalates to identity fraud. In Indonesia, the NIK is a critical identifier used for banking, SIM registration, and government services. Leaking this alongside a phone number significantly aids “Pinjol” (illegal loan) fraud.
• Targeted “Fan” Phishing: Cybercriminals can leverage the victims’ passion for the sport. They might send messages posing as Proliga officials offering “Exclusive Meet & Greets” or “Player Signed Merchandise” to trick fans into handing over credit card details or downloading malware.
• Database Cross-Referencing: Attackers often cross-reference sports databases with other leaks (like e-commerce breaches) to build a more complete profile of a target’s spending habits and financial status.

Mitigation Strategies

To protect fans and the integrity of the league, the following strategies are recommended:

• Official Channel Verification: Proliga should issue a statement advising fans to ignore any email or WhatsApp message regarding ticket cancellations or refunds that does not come from the official ticketing partner.
• Credential Reset: Users of the Proliga app or website should immediately change their passwords, especially if they use the same password for their email or banking apps.
• Scam Awareness: Fans should be wary of third-party ticket sellers on social media. The leak of phone numbers may lead to an increase in scammers offering “insider tickets” via direct message.
• Data Minimization: Future ticketing systems should avoid storing NIKs or full ID details unless legally mandated, to reduce the blast radius of future breaches.
