Mullvad VPN doesn't pick your outgoing (exit) IP address randomly every time you connect. Instead, it uses a fixed, predictable math formula based on your WireGuard connection key
Because of a quirk in how their random number generator works, the IPs you get on different servers always follow very similar patterns
The researcher tested thousands of keys and found only 284 unique IP combinations reeee - creates an easy "fingerprint" that can link your different connections or accounts together
