The electronic underground community is a closed culture grown around electronic/computer security.
It includes: *Hacker community *Phreaker community *Virus coder community
The people of this community share a near-obsession for technology, and some are very paranoid. They usually gather around their own ezines, see Underground ezines, and usually like BBS and Mailing lists and the Usenet.
There are some other communities surrounding the underground community, but not part of the community itself, for example, the script-kiddie community.
