Dave Buchwald

Filmmaker Dave Buchwald, once known as Bill From RNOC (/ˈɑːrnɒk/; born September 4, 1970) was a phone phreak, hacker, and leader of the Legion of Doom in the mid-1980s.

In the late 1980s, as a teenager, Buchwald was a social engineer, with the ability to manipulate phone system employees anywhere in the United States. In addition, he had a hacking skill with regard to Bell and AT&T systems (specifically COSMOS, SCCS, and LMOS), which allowed him virtually unrestricted access to phone lines, including the ability to monitor conversations, throughout the country. He was the lead author of the PENIX suite of hacking tools. Some of his original ideas are still in use by social engineers and security professionals today.

In 1995, Dave was introduced to film making when he served as a technical consultant to the movie Hackers, editing the screenplay and personally coaching many members of the principal cast.

In 1997, Buchwald co-founded Crossbar Security with Mark Abene (a.k.a. Phiber Optik) and Andrew Brown. Crossbar provided information security services for a number of large corporations, but became a casualty of the dot-com bubble. Crossbar Security went defunct in 2002, largely due to cuts in corporate security spending and an increase in the cost of corporate computer security advertising.
