Upon safe verification, the team found multiple indices, each storing millions of detailed records.
These datasets included:
- Users — containing personal details, contact info, and account metadata
- Payments — recording payment modes, dates, and linked user IDs
- Animal Records — storing breeder, ownership, and pedigree information
Total Size: 493.21 GB
Total Documents: 4,180,195,013
The server was fully open, indexed on Shodan, and accessible through a standard browser—an alarming lapse in security for a platform handling personal and financial data.
What Data Was Compromised 💾
The Working-Dog.com data leak involved three major indices, revealing just how much data the platform stored about its global user base. Kaduu researchers analyzed the structure and confirmed multiple categories of personal and transactional information.
- User Records
Fields identified included:
- id, created, updated
- firstname, lastname, gender, birthday
- address (zip, street, city, country_code_iso)
- email, role_name, state_name
- profile_visits, contact_count, results_count

These records exposed breeder details, emails, phone numbers, and addresses, linking people directly to animals and kennel operations.
The Scale of the Exposure 📊
This unsecured server exposure ranks among the largest publicly discovered in 2025. The dataset spanned over 15 years, containing entries from 2009 through 2024, indicating long-term archival data left unprotected.
Experts confirmed that the server ran an Elasticsearch instance with no authentication layer, making it directly visible to the internet and indexed by Shodan. Any user who knew the IP could browse the data freely.
Such a setup suggests either misconfigured backup storage or abandoned infrastructure, highlighting the risks of poor lifecycle management in cloud environments.
Expert Insight 🧩
According to Dr. Lena Hoffmann, cybersecurity researcher and author of Data Exposure by Default, “Open Elasticsearch clusters remain one of the biggest causes of major data breaches today. The Working-Dog.com case is yet another reminder that configuration mistakes can have devastating consequences.”
Kaduu spokesperson Andrej Kovač emphasized, “The most concerning aspect is the exposure of breeder and owner personal details. Unlike passwords, you can’t change your home address or date of birth once it’s leaked.”
Risk and Impact 🧨
The Working-Dog.com unsecured server leak discovered by Kaduu potentially impacts:
- Dog breeders, owners, and kennel managers
- Registered platform members and event participants
- Users with payment or membership history
Key risks include:
- Identity Theft: Exposed names, birthdays, and locations can be cross-referenced in fraud schemes.
- Phishing & Social Engineering: Attackers may impersonate Working-Dog.com support to steal credentials.
- Targeted Scams: High-value breeders could be tricked into fake sales or “premium listing” scams.
- Reputational Damage: Public exposure of breeder and kennel data undermines professional credibility.
The breach illustrates how unsecured cloud infrastructure can endanger not only data but also entire online communities built on trust and transparency.
Practical Tip 💡
If you have ever used Working-Dog.com, take immediate action:
✅ Change your password and avoid reusing it on other sites.
✅ Be cautious of emails claiming to be from Working-Dog.com.
✅ Use two-factor authentication wherever possible.
✅ Monitor your digital footprint for any signs of exposure.
✅ Consider using dark web scanning tools for early alerts.
Why DarknetSearch.com Is Crucial for Dark Web Monitoring 🌐
In modern cybersecurity, cyber threat intelligence is not optional — it’s essential 🛡️. As the Working-Dog.com data leak proves, once data is exposed, it can appear on darknet marketplaces or hacking forums within hours.
That’s where DarknetSearch.com becomes indispensable. It’s not just a dark web search tool—it’s a specialized intelligence platform that continuously scans deep web, darknet, and breach databases to identify leaked credentials, stolen records, or personal data.
Unlike traditional search engines, DarknetSearch.com focuses exclusively on hidden networks like Tor and I2P, where stolen information often surfaces first. By tracking these environments, it helps organizations detect threats before attackers exploit them 🚨.
Real-Time Threat Detection
DarknetSearch.com monitors underground sources in real time. When new data matching your email, domain, or organization appears, it instantly alerts you. This early detection allows for proactive mitigation, stopping breaches before they spread.
