Hacker (computer security)

Bruce Sterling traces part of the roots of the computer underground to the Yippies, a 1960s counterculture movement which published the Technological Assistance Program (TAP) newsletter.[citation needed] TAP was a phone phreaking newsletter that taught techniques for unauthorized exploration of the phone network. Many people from the phreaking community are also active in the hacking community even today, and vice versa. Several subgroups of the computer underground with different attitudes use different terms to demarcate themselves from each other, or try to exclude some specific group with which they do not agree. According to Ralph D. A grey hat hacker is a combination of a black hat and a white hat hacker. A neophyte, "n00b", or "newbie" is someone who is new to hacking or phreaking and has almost no knowledge or experience of the workings of technology and hacking.[10] Intelligence agencies and cyberwarfare operatives of nation states.[17] Vulnerability scanner Password cracking

Networking Fundamentals Networking Fundamentals In order to get the most of The TCP/IP Guide, a certain level of knowledge regarding the basics of networking is very helpful. Unlike many other resources, however, I did not want to start with the assumption that my reader knew what networking was all about. After all, that's why you are reading this Guide!

The main purpose of the LCP program is user account passwords auditing and recovery in Windows NT/2000/XP. I haven’t tested it against Windows Vista yet, so I’m not sure if it will work. How it works: Windows NT, 2000 and XP passwords are stored as encrypted hashes. Eventually the correct password will be sent and then displayed to the screen. Good intentions: System administrators can find weak passwords within minutes. Bad intentions:
