Dunno. Was just a big open text dataset. All with hire dates. It's possible it was archival which explains the telnetting being so easy, but every col was filled with plenty of young DOBs.

In my friends defence, this was performed by receiving the instructions from their US friend in their IRC "hacker clan" who discovered the hack. My friend doubted it but then got in and very quickly left. Despite being performed at their university's lab on their network, the friend still got a visit from federal officers from their country who said, quote, "You're not in trouble, but the path you're on leads to a bad life."

Friend now works in cyberfraud. Whatever whitehatting for a living is called these days... The same simple slip ups, routes, and tricks leading to breaching have not changed, just the protocols in which they're done with.
