Case Study
Investigating Sensitive Information Leak in a Publishing Business
Customer Profile
Industry: Publishing and Book Distribution
Business Overview: A mid-sized publishing business with operations involving the creation, management, and distribution of books across multiple languages and categories. Its business depended on protecting commercially sensitive information, including pricing and other internal business data.
The Problem: Confidential Pricing Leaks & Endpoint Risk
The organization experienced repeated data leakage of confidential pricing information, creating significant business and commercial risk.
Preliminary analysis indicated that the leaks were originating from five possible endpoints, but there was no clear evidence identifying the responsible user or the method of data theft.
The customer engaged Eagle to perform a security investigation to identify the source of the leakage, analyze user activity, review endpoints, correlate audit logs, and determine how sensitive information was leaving the organization. The objective was to establish evidence-based findings before implementing security controls.
The Solution: Digital Forensics & DLP Implementation
Eagle conducted a forensic investigation across the identified endpoints, analyzing file access logs, endpoint activity, emails, user behavior, USB usage, audit trails, and data movement patterns to identify the root cause of the data leakage.
Based on the findings, Eagle put controls in place to monitor how sensitive pricing information was accessed, copied, transferred, and shared. Alerts and controls helped identify and prevent unauthorized sharing of confidential information.
These controls helped the organization understand where sensitive data was being leaked and take appropriate action. Data Loss Prevention (DLP) helps organizations prevent sensitive data from being shared without authorization.
Conclusion:Â
By combining a security investigation with data protection controls, Eagle helped the organization identify the source of sensitive data leakage and establish stronger controls over confidential business information.
The customer gained improved visibility into endpoint activity, enhanced protection against insider threats, and a proactive framework for preventing future data leakage. The engagement reinforced a key cybersecurity principle: effective data protection begins with understanding how sensitive information moves before controlling where it can go.

Frequently Asked Questions
How do you investigate internal data leaks across company endpoints?
Eagle conducts digital forensic investigations by analyzing file access logs, email trails, USB usage patterns, and user activity across suspected endpoints to trace unauthorized data movement without disrupting operations.
Why is Data Loss Prevention (DLP) essential for publishing companies?
Publishing companies rely heavily on commercially sensitive data like pricing strategy, unreleased manuscripts, and distribution agreements. DLP controls monitor and restrict how this intellectual property is accessed, copied, or shared.
What is the difference between Digital Forensics and DLP implementation?
Digital Forensics investigates past security incidents to identify the source and method of a breach, whereas Data Loss Prevention (DLP) puts real-time monitoring and controls in place to block unauthorized data sharing before it happens.
How do you identify insider threats without concrete evidence?
When data leaks occur without a known perpetrator, security teams correlate endpoint activity, file access timestamps, network transfers, and USB usage logs across suspected devices to isolate anomalous behavior and identify the source.
What are the primary endpoint indicators of sensitive data theft?
Key indicators include unexpected USB device connections, large email attachment transfers, unauthorized access to sensitive pricing or IP files outside normal working hours, and unapproved cloud storage uploads.
