Enhancing Product Security through Mitigation of Enumeration Attacks

BDIT successfully enhanced a finance application by identifying and rectifying potential points of exploitation for enumeration attacks, overcoming challenges such as system complexity and a large user base (200K+ businesses). This 10-month project resulted in significantly reduced risk of data breaches and a comprehensive migration guide for a smooth transition to a more secure application.

About the Client

Our client, a finance startup, places paramount importance on protecting their extensive volume of sensitive data and customer information within their application. Recognizing the confidential nature of this data, they are dedicated to implementing robust measures to maintain the trust of their customers.


About the Project

BDIT was approached by the company seeking assistance in identifying and resolving potential vulnerabilities within their application’s web endpoints that are susceptible to enumeration attacks.

The project team consisted of two dedicated full-time Front-End Engineers who collaborated closely with the client’s team and participated in weekly sync meetings.


Project Goals

Our primary objective was to locate and categorize vulnerabilities while proposing a timeline for their remediation.



Throughout the course of the project, we encountered significant challenges:

System complexity

The complexity of the system presented a major challenge in detecting and addressing vulnerable areas within the interconnected environment, requiring a thorough approach to ensure comprehensive security coverage.

Phased Update Implementation

Considering the significant user base of the application (200K+ businesses), we employed a phased approach to implement updates. This gradual rollout required careful coordination and planning to ensure the updates are implemented correctly across different environments and only to a specific percentage of the user base.

Identification of Vulnerabilities

The process involved conducting thorough research, analysis, and testing to uncover weak spots. Differentiating between genuine vulnerabilities and false positives was critical, and each of them went through verification and validation to ensure accurate results.



1. Reduced Risk of Data Breaches:

Through identifying and fixing entry points for enumeration attacks, strengthening overall security, and addressing vulnerabilities, the application became more resilient to malicious attempts, safeguarding sensitive data and customer information from unauthorized access.

2. Migration Guide:

We actively contributed to the development of a migration guide, empowering other team members to independently manage areas within the application that could be exploited.

In conclusion, BDIT successfully completed the project within the span of 10 months. To ensure comprehensive coverage of this extensive and complex system, the team conducted thorough analysis to identify and fix potential vulnerabilities, specifically targeting enumeration attack points. The updates were implemented gradually and meticulously to prevent disruptions to existing services and the user base. These efforts mitigated the risk of data breaches, and offered a valuable migration guide. By eliminating these attack possibilities, BDIT has created a more stable and dependable system, fostering trust and confidence in client’s services.
