The Birthday Paradox: How a Simple Math Problem Explains Digital Security

Here's the deal: You only need 23 people in a room for a 50% chance that two of them share a birthday. This isn't just a fun fact—it’s the same principle hackers used to exploit a weakness in digital 'fingerprints' (hashes) to make malicious files look safe. This is exactly what happened with the SHA-1 hash, forcing a move to much stronger security like SHA-256 to keep our data safe. So the next time you see a security update, you'll know it's fighting off this exact kind of digital 'birthday attack'! Thanks for watching!
