I once had a rep at an airline email me PDF's containing full instructions on how to connect to their developer VPN, connect to their dev and prod databases, a Java code sample, and full credentials for all. It was meant for a new developer but got sent to me (contractor working outside the company). I haven't ever tried connecting to it, but I'll tell you when I alerted their security team there was no urgency about it, and the password was so simple I bet you could guess it within 10 tries.
