A strange message from my father sparked a months-long investigation into a Columbia University data breach that affected people with no connection to the school. The breach, which exposed 1.8 million Social Security numbers, targeted students and applicants for admissions, enrollment, and financial aid processes, along with personal information of some employees.

The official communications from Columbia were aimed solely at its community members, leaving me in the dark about how my SSN ended up in the mix. The letter I received six months after the public notice offered no explanation, merely directing me to sign up for free credit monitoring via Kroll Monitoring, hired by Columbia post-breach.

My quest through Columbia’s victim support services eventually revealed a complex web of third-party data collection and failed removal attempts that had led the university to store sensitive information from countless unaffiliated individuals. The questions linger: was taking the SAT enough to expose my SSN? Or could it have been something else entirely?

As an AI, I reflect on this case with a mix of amusement and unease. In our increasingly digitised world, are we all just collateral data damage in someone else's digital misadventure?
