- How many people do you know who have a unix workstation at home that runs the
- same executables as the one at the office? Some versions of the same
- workstation won't even run each other's executables so for Joe to take an
- executables file home with him is VERY rare.

- Almost all multi-user systems I have been on have had write permission denied
- as a default.. Even on systems that don't (considering a different version
- would need to be done for each OS) the virus could be restricted so it looks
- in YOUR root directory (I can't see why it would do otherwise) for the marker
- file, and will not do anything unless the marker file AND the executable
- you're running belong to you. That's incredibly easy.
-
- This way the sysadmin could install the virus for bin (who usually has root
- privs, or very near) and it would just pack the files in /bin.. Considering a
- user has absolutely no need to look at the executable then this would be a
- 100% legit way for the sysadmin to pack the files without being obligated to
- tell you.

-
- Where did you get this idea? If that was the thought of the virus writer then
- they wouldn't make it dependant on a marker file.
