Dataharvest 2025 - the European Investigative Journalism Conference

Prompted by nearly 2 TB of leaked data, a recent collaborative investigation co-run by OCCRP and SVT shed unprecedented light on the inner workings and processes of two major scam call centre networks that conned victims out of at least US$275 million over four years. This session will cover how we approached this leak, which included millions of multilingual audio and video media, among other data formats, and how we made it possible for journalists to search that data like any trove of documents.

Journalists should walk away with a better understanding of the challenges and breakthroughs of modern leaks and the methodologies and tools media organizations can employ today in investigations.
