- CloakShare
-
- By Eric Traut & Dan Clifford
- June 17, 1993
-
- CloakShare is a small hack which “cloaks” the presence of your computer
- from novice users on a network. We wrote it when we were at Stanford
- University and secretly hooked into the campus network. We wanted to
- be able to run file sharing to swap files, but we didn’t want to show
- up in other people’s Choosers.
-
- The INIT works by patching PBControl. When the patch sees anyone
- performing an NBP name register, it compares the name to “AFPServer.”
- If the name matches, the patch changes it slightly (changes is it
- “AFPSërver”) and continues with the registration.
-
- When someone performs an NBP name lookup, the patch once again compares
- the name against “AFPServer”. If it matches, an NBP lookup is done on a
- string with a wildcard character (“AFPS≈rver”).
-
- The resulting behavour is such that everyone running CloakShare can
- see ALL file servers (even those that are cloaked), but network users
- without CloakShare continue to look for just “AFPServers” and don’t
- see the cloaked servers.
-
- Known Problems:
- Only AppleTalk 2.0 and greater know about the wildcard character for
- NBP lookups.
-
- People with network sniffers or a little more knowledge of the network
- will still be able to detect the presence of a Cloaked file server.
-
- Distribution:
- Feel free to modify this code in any way you want. If you distribute
- the code, please include this ReadMe file. The authors are not
- responsible for any damage, destruction, chaos, etc. caused by this
- extension. Use at your own risk.
