In my years working at one of the largest telecommunications companies, I spent most of my days immersed in the world of data governance. It sounds dull, maybe even monotonous to some, but there’s something captivating about massive datasets, flowing like rivers through servers and systems. I was responsible for running tests on these databases, ensuring integrity and compliance. It was routine work—until it wasn’t.

I stumbled upon something that didn’t sit right. Customer data—phone numbers, browsing histories, even their locations—was being accessed by third parties. Not just any third parties, but external agencies, without any court orders or even a shred of customer consent.

The databases were structured in massive clusters, each containing hundreds of terabytes of customer information. I ran queries across different dimensions, cross-checking the access logs against authorized user lists. But the access timestamps? They didn’t add up. Requests for data were being fulfilled by automated scripts that weren’t tied to any internal operation. These scripts were rogue, siphoning off gigabytes of personal information and forwarding them to agencies. All of it, unauthorized.

Technically, the data had been partitioned using Hadoop Distributed File System (HDFS) across multiple nodes. This system was designed for scalability and speed, but in the wrong hands, it became a tool for secrecy and exploitation. The scripts I uncovered were using an obscure API call to bypass the standard governance checks. They were able to copy entire datasets and redirect them—out of our control, out of sight, and into the hands of agencies that had no legal right to this information.

The customers had no idea. The calls, the texts, the locations—they thought these were private, hidden behind layers of encryption and trust. But trust? Trust is fragile, and in the wrong hands, it shatters.

Lesson learned: nothing is private. The data you think belongs to you, is often already out of your control. We trust systems we don’t understand, giving away pieces of ourselves, bit by bit. But the reality is this: your data, your life, can be traded like a commodity, often without your knowledge or consent.

What can you do? Be conscious of where your data goes. We need to take back what’s ours before we’re nothing but datasets traded behind closed doors.
