Brinztech Alert: The Alleged Database of Ek-territory.ru is Leaked

Dark Web News Analysis

The dark web news reports a significant data breach involving Ek-territory.ru, a digital platform linked to the “My Territory” mobile app. This service is used by residents to manage service requests, submit meter readings, and communicate with building management companies.

A threat actor group known as Team 4B1D is claiming responsibility for the leak. The compromised dataset reportedly consists of several SQL database files. The leaked information is extensive, covering CRM Contacts, User Details, Sales Orders, and specific Property Values. This suggests the attackers dumped the core operational database, exposing the link between digital user accounts and physical real estate assets.

Key Cybersecurity Insights

Breaches of property management apps (“PropTech”) are uniquely intrusive because they reveal the private habits and physical locations of residents:

• Utility Bill Scams: The leak includes data on Meter Readings and Service Requests. Scammers can use this to send highly convincing fake utility bills via email or SMS: “Your electricity payment for [Address] is overdue. Pay immediately to avoid disconnection.” Because the scammer knows the victim’s address and recent usage patterns, the fraud is hard to detect.
• Physical Security Risks: The exposure of Full Names linked to Physical Addresses and potentially Property Values creates a “burglar’s shopping list.” Criminals can identify high-value properties or target individuals known to be away (e.g., if the user data indicates a vacation hold on services).
• CRM Exposure: The leak of CRM Contacts means the entire history of a resident’s complaints or requests is visible. Attackers can use this for social engineering, posing as the “Management Company” following up on a specific repair request to gain entry to the apartment or solicit “service fees.”
• SQL Injection Vulnerability: The fact that the data is in SQL files often points to an SQL Injection vulnerability or a misconfigured database backup left exposed on the web, a common failing in rapid-growth PropTech platforms.

Mitigation Strategies

To protect residents and property data, the following strategies are recommended:

• Official App Verification: Residents should strictly use the official “My Territory” app for payments and ignore any third-party links sent via SMS or email demanding payment.
• Password Rotation: Users must change their passwords for the Ek-territory service immediately.
• Doorstep Vigilance: Be skeptical of anyone visiting your apartment claiming to be from the management company to “fix” an issue you didn’t report, or one that matches a recent legitimate report (as the attacker may know about it).
• Database Audit: The administrators of Ek-territory.ru need to perform a forensic audit to identify how the SQL dumps were exfiltrated and patch the vulnerability.
