A hacker has exposed the personal records of over 33,000 employees after discovering unrestricted endpoints belonging to a major technology service provider.
The breach, first reported by cybersecurity platform CloudSEK’s BeVigil, highlights alarming gaps in API security that could have far-reaching consequences for both the affected organization and its clients.
CloudSEK’s BeVigil, a platform specializing in continuous security monitoring, identified several misconfigured API endpoints tied to the service provider’s internal web application.

Unlike securely designed APIs, these endpoints required no authentication, allowing anyone on the internet to access and download sensitive data with a simple HTTP request.
The leaked information includes:
- Employee Personal Data: Names, corporate email addresses, and department details.
- Asset Configurations: Information on hardware, software, and provisioned devices.
- Project Structures: Internal workgroup assignments and ongoing project details.
“This was essentially a door left wide open for attackers,” said a BeVigil spokesperson. “Anyone could have walked in and taken what they pleased.”
The risks posed by this breach go far beyond the initial exposure of employee records. According to security experts, attackers could exploit the data for:
- Social Engineering Campaigns: Using employee names and departments to craft convincing phishing emails or impersonate internal IT personnel, potentially extracting credentials or spreading malware within the organization.
- Mapping Organizational Structure: Identifying key personnel, tracking movements across business units, and mapping internal project teams—information invaluable to cybercriminals plotting future attacks.
- Surveillance and Espionage: Since the API data was updated in real-time, it enabled continuous monitoring of infrastructure changes and employee activities, increasing the risk of further breaches.
Urgent Steps for Organizations
The exposed provider has since moved to contain the breach, but security analysts warn that the incident illustrates a systemic problem. Key recommendations include:
- Restrict All API Access: Enforce strict authentication and authorization on every endpoint.
- Encrypt Sensitive Data: Ensure that all personally identifiable information (PII) is encrypted before transmission.
- Real-Time Monitoring: Deploy automated tools to detect unauthorized API access.
- Credential Rotation: Change all potentially compromised API keys and user credentials immediately.
This incident serves as a sobering lesson for organizations relying on third-party platforms. “APIs are the backbone of modern digital services, but if left unprotected, they can also be a company’s greatest liability,” CloudSEK’s spokesperson added.
As data security continues to be one of the most pressing challenges for modern enterprises, experts urge organizations to adopt robust API security measures—before a minor oversight leads to a catastrophic breach.
