Abstract: In a recent attack on the Texas A & M computer complex, which consists of over 12,000 interconnected PCs, workstations, minicomputers, mainframes, and servers, a well-organized team of hackers were able to take virtual control of the complex. Having broken in by running password-cracking programs, the intruders then modified login software to enable them to capture additional passwords of users logging on to systems. The team complied files containing hundreds of captured passwords, including some on major and supposedly secure servers. One local machine was set up as a hacker bulletin board, which the hackers used to contact each other, to discuss techniques and progress, and to disseminate the captured passwords.
