The Power of Open Source: This Week’s Critical Intelligence Wins with OSINT Techniques — VIEH Security Research Team
At VIEH Security, we’re not just a team of researchers; we’re a team of investigators. We believe that the best defense starts with understanding our own exposure, and we use Open Source Intelligence (OSINT) to do just that. This past week, our methodology proved its value once again with a critical discovery that highlights the power of creative thinking.
Our team was conducting a routine scan, not for vulnerabilities, but for what we call “digital breadcrumbs” — small, seemingly insignificant details left behind in public spaces. That’s when we found it: a publicly accessible backup snapshot that contained developer keys.
The discovery wasn’t a fluke. It was the result of our structured and methodical approach. The initial lead wasn’t even a file, but a tiny piece of metadata — a timestamp in a public PDF on a vendor’s support portal. This small detail, often overlooked by automated scanners, pointed us toward a publicly exposed developer mailbox. From there, we were able to safely and manually validate the existence of the misconfigured backup.
This incident wasn’t about a single vulnerability; it was a perfect example of how small oversights can lead to a major security risk. The developer keys were a significant find, but the underlying issue was a complete breakdown in publishing controls and data hygiene. It’s a reminder that OSINT isn’t just about what you find; it’s about what you can prevent.
Our Core Beliefs on OSINT
Our approach is built on a few core principles that guide every investigation:
- OSINT is a mindset: It’s not just about a list of tools. It’s about thinking like an adversary and understanding how they would piece together a company’s public digital footprint.
- The Power of Triangulation: We never act on a single source of information. Every finding is corroborated with multiple data points to ensure it’s accurate and actionable.
- Responsible Disclosure is Paramount: Our goal is to fix, not to exploit. When we find a vulnerability, we work with the affected organization to provide a full report and remediation steps in a private and responsible manner.
A Closer Look: The VIEH Security Process
We’ve refined our methodology to be a repeatable, low-cost way to identify your own blind spots.
- Objective: We start with a clear objective. In this case, it was to find accidental data exposure.
- Collection: We used a combination of targeted searches on public code repositories and passive scanning tools to collect a broad range of data.
- Analysis: The key to our success was the deep analysis of metadata. We found that timestamps, author names, and internal file references in public documents can reveal a surprising amount of information.
- Action: Once we confirmed the risk, we immediately notified the organization. They were able to remove the exposed keys, rotate credentials, and implement tighter controls to prevent future leaks.
This discovery reinforced our belief that every publicly facing artifact — from a simple PDF to a public code snippet — is a potential security risk. By monitoring these small signals, we can uncover and address large issues before they are exploited.
It’s about being proactive. It’s about thinking differently. It’s about security.
