T 5.41 Misuse of an UNIX system with the help of UUCP
The program packet UUCP (Unix-to-Unix Copy) allows for exchanging ASCII and binary files between IT systems and for executing commands on remote IT systems. Initially, UUCP was restricted to Unix systems, but is meanwhile also available for many other operating systems. During communication using UUCP, IT users on remote computers are granted rights on the local computer. If these rights are not granted carefully and so that that they are restricted to the necessary extent, there is the risk of the local system being misused. A masquerade using UUCP is also conceivable through simulation of a host, for example, if the password is known.
