NEW YORK (AP) — One of the more striking pieces of journalism from the Ukraine war featured intercepted radio transmissions from Russian soldiers indicating an invasion in disarray, their conversations even interrupted by a hacker literally whistling “Dixie.” It was the work of an investigations unit at The New York Times that specializes in open-source reporting, using publicly available material like satellite images, mobile phone or security camera recordings, geolocation and other internet tools to tell stories. The field is in its infancy but rapidly catching on. The Washington Post announced last month it was adding six people to its video forensics team, doubling its size.
