Brinztech Alert: The Alleged Database of Holywings Group is Leaked

Dark Web News Analysis

The dark web news reports a significant data breach involving Holywings Group, a major hospitality and nightlife chain in Indonesia. A threat actor has claimed to leak a database containing the personal information of over 60,000 users, with the breach purportedly occurring in December 2025. The data is currently being offered on a hacker forum, accessible to users who reply to the thread or upgrade their account. The leaked SQL sample indicates a deep exposure of Personally Identifiable Information (PII), including National IDs, phone numbers, gender, dates and places of birth, physical addresses, and notably, religion.

Key Cybersecurity Insights

Breaches in the lifestyle and hospitality sector usually target credit cards, but this specific dataset poses unique social and physical risks:

• Sensitive Profiling (Religion): The exposure of the “Religion” field is particularly sensitive in Indonesia. Malicious actors could use this data to profile customers for targeted discrimination, political polarization campaigns, or specific social engineering attacks that exploit religious sentiments.
• Identity Theft Construction: The combination of Place/Date of Birth, Phone Number, and Address provides nearly all the components needed for full identity theft. Attackers can use these details to apply for loans or register fraudulent SIM cards in the victim’s name.
• Physical Security Risks: The exposure of home addresses combined with lifestyle data (patronage of nightlife venues) creates physical security concerns. Stalkers or criminals could target high-value customers identified through their spending habits or frequent visits.
• Social Engineering: Scammers can pose as Holywings management, contacting victims via WhatsApp: “We are updating our membership database. Please confirm your ID number to keep your points.” The availability of real data makes these scams highly convincing.

Mitigation Strategies

To protect customer safety and privacy, the following strategies are recommended:

• Customer Notification: Holywings Group must proactively notify the 60,000 affected users. Transparency is critical to maintaining trust. Users should be warned specifically about scams asking for personal validation.
• MFA Implementation: Implement Multi-Factor Authentication (MFA) for any app or membership portal associated with the group. This prevents attackers from using the leaked data to take over accounts and redeem loyalty points.
• Data Minimization Policy: Review why sensitive fields like “Religion” are being stored for a hospitality service. If this data is not strictly necessary for operations or legal compliance, it should be purged to reduce future liability.
• Dark Web Monitoring: continuously monitor the forum thread to track the spread of the data. If the database becomes public (no longer behind a paywall/reply-wall), the risk of mass automated attacks increases significantly.
