GetReal co-founder and Chief Science Officer Dr. Hany Farid joined CBS Sunday Morning this week for a wide-ranging conversation with Ted Koppel about deepfakes, AI-generated imagery, and what happens when we can no longer simply trust what we see and hear.

The segment opens on a case that captures what’s at stake: When a grainy, shaky video emerged as evidence in a contested missile strike, several news outlets turned to Farid to determine whether it was authentic. With little to work with, his team reasoned from physics — the speed of sound, the speed of light, the size of the object — to assess whether what the footage showed was physically plausible. That scientific approach is the throughline of his work, and of GetReal's.

It's also why explainability matters so much. As Farid told CBS, it isn't enough for an analyst to conclude something is real or fake because "the computer told me so." In a courtroom, a newsroom, or a boardroom, you have to be able to explain why. That means looking at the operations behind what's onscreen and being able to tell someone exactly what you’re looking for.

The conversation also made clear how widely this technology is already being weaponized, from state-sponsored disinformation to the North Korean operatives who interview for remote IT jobs while using AI to conceal their accent, their location, and even their face, swapping their identity in real time over a video call. By Farid's estimate, these aren't fringe incidents: he believes just about every Fortune 500 company has hired one or more of these workers, knowingly or not.

And the threat is still evolving. Today's deepfakes almost always have a human somewhere in the loop, operating the attack. The next shift, Farid explains, is autonomous AI agents that can create their own fake identities, interact with real people to get them to act, and cover their tracks afterward.

The takeaway isn't to stop hiring remotely, abandon video calls, or retreat from the technology. As Farid put it, flying every candidate across the country can't be the answer. The answer is building the ability to determine what's real as the technology keeps changing — in real time, continuously, and with evidence you can explain.

That's exactly what Hany and the team at GetReal Security work to solve every day.
