What really grinds my gear are banks and their security theater.
Here in Chile you can trivially find anybody's national ID number "RUT" but still banks send you bank statements by email in encrypted PDFs - using 4 digits out of that RUT. I tried it out. It takes my cheap laptop on average 16s to figure out the right digits.
