> Just a matter of time for ransomware to replace data via APIs.

I asked about this in a cybersecurity meeting at an investment bank a few years ago - how much security is there around Bloomberg's data feed? All of the algorithms that make million & billion dollar decisions rely on that data so I asked if someone stepped in the middle and fed the algorithms bad data or even slightly delayed data would we even know it had happened? They looked at me like I was a crazy person. I'm actually kind of surprised it hasn't happened yet. Or maybe no one has noticed yet.
