Windows viruses hitting linux.....

[Correale, Ernest]

I have had this happen to me.  At the company I was working for at the time,
a secretary opened vbs.Loveletter on her computer.  It destroyed files on
her PC as well as files on all drives mapped from samba shares.  We had to
recover several Unix servers from tape.  
-- Needless to say, she had several long discussions with us that day.

This occurred when loveletter 1st came out and before the DATs where
available.  It was most-definitely not a lot of fun.

If its a samba share and its world-writeable, Windows viruses will 
happily do whatever damage they would normally do to a local drive or 
Windows share.

If this is a problem, then you really should have anti-virus software 
running on all the machines, otherwise you're just inviting a disaster...

Subject: Windows viruses hitting linux via network shares

Yet another virus is on us. This one comes via windows and when executed
will erase your hard drive, or whatever.
I have a home network with windows clients on it. So far, nobody has done
the unthinkable, but they might some day.
I have all the boxes hooked together with a samba network. Seems to work OK.
I have all the clients as guest = ftp. This means that they couldn't write
to most of my directories (or erase them) but there are plenty of files and
probably some directories which are world writeable and erasable.
So, question is, if one of these malicious viruses executed on a windows
client, how much damage would one expect to the world writable directories
and files on my linux boxes (Forget the windows boxes. I would gladly tell
my windows users it was a shame.)
While I await the answer, I am going to change all my shares to read only.
On second thought, using the magic of samba, I'll let the linux boxes 
have write privileges.
