Steps againt Nimba Worm for Samba
Last Updated: 2001/09/22
Author: HASEGAWA Yohsuke
Translator: TAKAHASHI Motonobu
The information in this article applies to
Samba 2.0.x
Samba 2.2.x
Windows 95/98/Me/NT/2000
SYMPTOMS
This article has described the measure against Nimba Worm for Samba
server.
DESCRIPTION
Nimba Worm is infected through the shared disk on a network besides
Microsoft IIS, Internet Explorer and mailer of Outlook series.
At this time, the worm copies itself by the name *.nws and *.eml on
the shared disk, moreover, by the name of Riched20.dll in the folder
where *.doc file is included.
To prevent infection through the shared disk offered by Samba, set
up as follows:
-----
[global]
...
veto files = /*.eml/*.nws/riched20.dll/
-----
Setting up "veto files" parameter, the matched files on the Samba
server are completely hidden from the clients and become impossible
to access them at all.
In addition to it, the following setting are also pointed out by the
samba-jp:09448 thread: when the
"readme.txt.{3050F4D8-98B5-11CF-BB82-00AA00BDCE0B}" file exists on
a Samba server, it is visible only with "readme.txt" and a dangerous
code may be performed when this file is double-clicked.
Setting the following,
-----
veto files = /*.{*}/
-----
no files having CLSID in its file extension can be accessed from any
clients.
This technical article is created based on the discussion of
samba-jp:09448 and samba-jp:10900 threads.
