Elon Musk caught a Tesla employee leaking secrets by sending each worker an identical email with one tiny difference: a single or double space. When the leaked version appeared in the media, the spacing revealed which employee had forwarded it. The leaker was then asked to leave.
Somebody tweeted at Elon, hey Elon, back in the day there was somebody who was leaking internal company data. They kept leaking it to news outlets. It was bad for business. I'm curious, how did you find them? Actually, it's an interesting story. We sent everybody in the company the same email, but with one slightly different space somewhere in the email. Between this period, we would either do two spaces or one space, but it was a long email. So we were able to create like a unique fingerprint for everybody in the company. We sent them all a slightly unique email, binary proof that this was your email that got out. And he's like, it was the fastest path to catching them. We asked them to pursue a career at another company. That's so clever. Samoš Černý.
