im the founder of a company that runs deepfake phishing simulations for enterprises, so biased on this one .. but the operational thing the piece misses is that this is the first widely circulated dump where voice, govt ID and selfie all came from the same onboarding session i.e. most enterprise call center auth still treats those as 3 independent factors ..

The scarier piece is that an attacker pulls a contractor from the dump, finds their employer on linkedin, then calls that companys IT helpdesk for a password reset with the cloned voice.

Fwiw we put up a free realtime face swap demo a while back at https://www.callstrike.ai/deepfake-security-training .. worth a look if you want to actually feel how trivial this has gotten.

Great point about the helpdesk vector. The LinkedIn-to-IT-reset path is a brilliant illustration of how social engineering chains work. And you're right that audio is the frontier video deepfake detection has gotten really good, lots of great tools out there. Audio is the next wave, and the teams building solutions for real-world call quality are going to unlock a massive market. Exciting space to be in.
