In the early days, the L0pht guys tinkered with what they already had laying around, or could find dumpster diving. But things change, of course. By the end of the ‘90s many of the L0pht hackers had quit their day jobs, incorporating under the name L0pht Heavy Industries and moving into a nicer space. Seven days after Y2K, they merged with @stake, an internet security startup. It was a signal that hacking wasn’t just for the kids anymore.
