Brinztech Alert: The Alleged Database of Menulux is Leaked

Dark Web News Analysis

The dark web news reports a targeted data breach involving Menulux, a prominent cloud-based POS (Point of Sale) and digital menu platform widely used in Turkey. A threat actor identified as @888 has allegedly leaked a database containing approximately 93,000 customer records on a hacker forum.

The compromised dataset includes highly sensitive Personally Identifiable Information (PII), specifically Full Names, Phone Numbers, and Physical Addresses. While financial data (credit cards) was not explicitly mentioned in the initial sample, the exposure of physical location data linked to personal identities poses significant privacy risks for the customers of restaurants and cafes using the Menulux system.

Key Cybersecurity Insights

Breaches of localized POS platforms create a concentrated threat landscape for specific regions:

• Hyper-Local “Smishing”: The combination of Phone Numbers and Names is the primary fuel for “Smishing” (SMS Phishing). Because Menulux is used for ordering and delivery, scammers can send texts in Turkish: “Your delivery order #8392 is pending. Click here to confirm address,” utilizing the stolen data to make the message look official.
• Physical Security Risks: The leak includes Physical Addresses. For high-profile individuals or victims of stalking, the public availability of their home address linked to their phone number is a severe safety threat. It also enables “Cash on Delivery” scams, where fraudsters send cheap items to the victim’s house and demand payment at the door.
• POS Supply Chain Vulnerability: Menulux acts as a third-party processor for many small businesses. This breach highlights the “many-to-one” risk: a single vulnerability in one software provider compromises the customers of hundreds of different restaurants.
• KVKK Compliance: As a Turkish company, this breach falls under the KVKK (Law on Protection of Personal Data). The exposure of 93,000 records will likely trigger an investigation by the KVKK board, leading to potential fines if negligence is proven.

Mitigation Strategies

To protect Turkish consumers and businesses, the following strategies are recommended:

• Scam Awareness: Users in Turkey should be suspicious of any SMS messages requesting payment or address verification, especially if they haven’t ordered food recently.
• Merchant Notification: Restaurants using Menulux should be transparent with their customers about the incident to maintain trust, rather than waiting for the news to spread via social media.
• Infrastructure Audit: Menulux must conduct a forensic analysis of their API endpoints and database access logs to determine how actor @888 bypassed security controls.
• KVKK Reporting: The company must notify the Turkish authorities and affected individuals within the legal timeframe to mitigate regulatory penalties.
