SWIM once said to me: Funny thing about those System 75's, the entire ordeal originated from the hack of a bank's telephone system, who had a small Unix UUCP network and, for some odd reason, put all their System 75 logins and passwords into their Systems file. The default login information leaked out after a hacker named Syadasti announced that he was willing to turn any System 75's given to him into usable remote PBXes, and eventually some other hacker (Scott Simpson, maybe? don't know) set up a system on his own home line that responded like a System 75 would, and gave Syadasti that number. He promptly tried to login with the cust/rcust accounts, which were recorded by the other hacker, which led to the explosion of System 75 hacks throughout the US.
