The Singburi Hospital data breach has become one of the most alarming cybersecurity incidents in Thailand’s healthcare sector in 2025. On September 25, 2025, a threat actor known as RobotMan posted a leaked database on DarkForums.st, claiming it contained 300,000 personnel records from the hospital’s official domains (singburihosp.moph.go.th / singburihosp.go.th). The compromised information was discovered by the Kaduu team during its routine dark web monitoring, and since then, the news has circulated widely on security trackers and darknet intelligence feeds. 📢

What Happened in the Singburi Hospital Leak?

On September 25, 2025, a user named RobotMan uploaded what they described as a personnel database from Singburi Hospital onto the darknet marketplace DarkForums.st. According to reports, the CSV file contained 300K records and weighed 6MB when compressed. Researchers found that the file fields included identifiers such as:

• cid
• pname
• fname
• lname
• birthdate
• father_name
• mother_name
• home_phone
  Such details can be exploited for a variety of malicious purposes, from impersonation to spear-phishing. The Kaduu team, which regularly conducts darknet monitoring, confirmed the post’s discovery. This aligns with breach trackers like HackNotice, which flagged the leak and highlighted its severity.

Who Is Behind the Data Breach?

The hacker, using the alias RobotMan, is credited as the author of the breach announcement. While little is known about this actor’s identity, their post on DarkForums.st suggests experience in data leaks and underground dealings. In many cases, actors post such databases either for notoriety, to build reputation in illicit communities, or as part of larger extortion campaigns.

As of now, there is no official confirmation from Singburi Hospital or Thailand’s Ministry of Public Health acknowledging the breach. However, multiple cyber-intelligence firms have logged the leak, increasing the likelihood that the data is authentic.

What Data Was Compromised?

Healthcare staff records are particularly valuable in the criminal ecosystem. In this case, the compromised information includes:

• Full names (first and last)
• Date of birth 🎂
• Family references (father’s and mother’s names)
• Contact numbers (home phone)
• Civil identifiers
  While the dataset does not appear to include patient health records, the exposure of staff data is nonetheless serious. Attackers can combine birthdates, family details, and phone numbers to carry out identity fraud, targeted phishing, and social engineering attacks.

Risks of the Singburi Hospital Data Breach

The risks linked to this incident extend beyond the hospital’s internal environment. Here are the most pressing consequences:

1. Identity Theft – Criminals can exploit names, birthdates, and family details for fraudulent registrations.
2. Phishing Campaigns – With accurate personal data, phishing emails or phone scams become more convincing.
3. Reputation Damage – As a government hospital, Singburi faces potential loss of trust among staff and the public.
4. Operational Disruption – Staff morale and internal workflows may be disrupted if personnel fear ongoing exposure.
5. Regulatory Impact – Depending on Thai data protection laws, the hospital may face fines or investigations. 🚨

How Did the Database Leak?

The exact vector of compromise has not yet been confirmed. However, common attack methods in healthcare breaches include:

• Exploited vulnerabilities in outdated hospital IT systems
• Phishing attacks against staff credentials
• Misconfigured databases exposed to the internet 🌐
• Insider threats or stolen access credentials
  Without an official statement from Singburi Hospital, the root cause remains speculative.

Expert Insights on Healthcare Breaches

Cybersecurity experts often warn that healthcare institutions are prime targets due to the combination of outdated IT systems and highly valuable personal data. According to IBM’s “Cost of a Data Breach” report, healthcare data breaches have the highest average cost per record compared to other industries. One security analyst commented:

“Even when patient records are not exposed, staff data can be just as dangerous in the wrong hands. It provides a stepping stone for targeted attacks on hospital infrastructure.”

Practical Tips for Staff Affected

If you are part of the Singburi Hospital personnel, consider the following checklist:
✔️ Be cautious with unsolicited emails or calls asking for sensitive information
✔️ Verify suspicious requests through official hospital channels
✔️ Enable two-factor authentication on all accounts where possible
✔️ Monitor bank accounts and credit records for unusual activity
✔️ Consider enrolling in identity theft protection services

Question: Is My Data Safe After the Singburi Hospital Breach?

If you are a staff member, there is a possibility your personal information was part of the leaked 300K records. Since the hospital has not released an official list of affected individuals, the safest assumption is to act as though your data may be exposed and follow protective measures immediately.

Why This Matters Beyond Singburi Hospital

The Singburi Hospital data breach is not just a local incident. It highlights a global pattern where healthcare institutions are repeatedly targeted because of poor cybersecurity funding and outdated infrastructure. 🌍 Related breaches have occurred across Asia, Europe, and North America, showing that healthcare systems worldwide must take proactive measures to safeguard employee and patient data.

The Role of Monitoring Teams

The discovery of the Singburi breach by the Kaduu team demonstrates the importance of continuous darknet surveillance. Without such monitoring, hospitals and employees might remain unaware of breaches until the data is misused. Proactive intelligence allows organizations to respond faster, notify affected staff, and reduce harm.

Conclusion

The Singburi Hospital data breach underscores how critical it is for healthcare institutions to strengthen cybersecurity defenses. With 300,000 staff records potentially compromised, the risk of identity theft, phishing, and reputational damage is real. While the hospital has not yet released an official confirmation, evidence from multiple cybersecurity monitoring sources makes this incident credible.

👉 If you are connected to Singburi Hospital, take precautionary steps now to secure your data. For organizations, this breach should serve as a wake-up call to invest in robust security measures before sensitive data ends up for sale on the darknet.
