Unprotected API Leaks Confidential Data of 33,000 Employee Records—BeVigil Raises the Alarm
This article highlights the severe risks associated with exposed APIs, based on a case where a major technology service provider inadvertently left API endpoints unprotected, compromising sensitive data of over 33,000 employees. The incident emphasizes the urgent need for effective API security measures to prevent unauthorized access and potential data breaches. Affected: technology service provider, employees

Keypoints :

  • Exposed API endpoints led to unauthorized access to sensitive employee data.
  • More than 33,000 employees’ personal information (PII) was at risk.
  • Attackers could easily access employee names, email addresses, asset details, and project information.
  • The situation can result in unauthorized data access and increased risks for cybercriminal activities.
  • Social engineering attacks could be perpetrated using the exposed employee details.
  • Immediate actions recommended include restricting API access, encrypting sensitive data, and monitoring API traffic.
  • BeVigil’s tools can help detect and resolve API misconfigurations before they lead to data breaches.

MITRE Techniques :

  • T1071 – Application Layer Protocol: Attackers exploit API endpoints to access sensitive data without authentication.
  • T1110 – Brute Force: Attackers may use brute force methods to gain unauthorized access to API keys or user accounts.
  • T1078 – Valid Accounts: Exposed endpoints could allow attackers to access and exploit valid account credentials from exposed data.
  • T1556 – Man-in-the-Middle: Attackers could intercept data transmission if sensitive information is not encrypted.
  • T1189 – Drive-by Compromise: Exposed clerical details of employees can lead to drive-by social engineering attacks via phishing.

Indicator of Compromise :

  • [Domain] serviceprovider.com
  • [Email Address] employee@example.com
  • [IoC Type] API Endpoint Access – /api/v1/employee_data
  • [IoC Type] IP Address – 192.0.2.1
  • [IoC Type] API Key – a1b2c3d4e5f6g7h8i9j0
