Hi All,

Sanesecurity rsync mirrors are reporting constant pounding with sites
requesting MSRBL signature databases. Sanesecurity *does not distribute
these signature databases*.

Please could you all check your script configurations and ensure that
MSRBL signatures aren't downloaded from the Sanesecurity mirrors (ie.
rsync.sanesecurity.net) and
are in fact downloaded from *rsync://rsync.mirror.msrbl.com/msrbl/

*MSRBL signatures have been removed from most download scripts now, as
the MSRBL signatures haven't been updated in over a year (last update:
2009/07/24).

Thanks Steve!

And to stress that this advice should not be ignored or taken lightly, some (possibly all) of the rsync mirror sites are blacklisting sites that constantly request MSRBL signature updates. There are currently 368 sites that are being block by the rsync blacklist. Once these sites remove the MSRBL requests from the download scripts and request delisting here on the Sanesecurity users list, they will once again have access to Sanesecurity signature updates. Until then, they will have no access to any Sanesecurity signature updates.

Please also note that Sanesecurity DOES NOT distribute SecuriteInfo signature databases, so DO NOT request those from the Sanesecurity rsync mirrors either, lest you also risk being added to the blacklist. For example, this will potentially get you added to the blacklist:

==========
rsync: link_stat "honeynet.hdb" (in sanesecurity) failed: No such file or directory rsync: link_stat "honeynet.hdb.sig" (in sanesecurity) failed: No such file or directory rsync: link_stat "securiteinfo.hdb" (in sanesecurity) failed: No such file or directory rsync: link_stat "securiteinfo.hdb.sig" (in sanesecurity) failed: No such file or directory rsync: link_stat "vx.hdb" (in sanesecurity) failed: No such file or directory rsync: link_stat "vx.hdb.sig" (in sanesecurity) failed: No such file or directory
==========

These are NOT Sanesecurity distribute signature databases, download these signature database from the SecuriteInfo download site.

I might also add that all script users should periodically check the output of their download script for errors. We are also seeing requests like the following:

rsync: link_stat "#.sig" (in sanesecurity)failed: No such file or directory

Caution, when using the clamav-unofficial-sigs download script, DO NOT PLACE ANYTHING BETWEEN THE QUOTE "" MARKS IN THE CONFIG FILE 'ss_dbs' DOWNLOAD SECTION EXCEPT VALID AND CORRECTLY SPELLED SANESECURITY SIGNATURE DATABASE NAMES. For example, as shown in the default config entry for Sanesecurity signature downloads:

ss_dbs="
   junk.ndb
   jurlbl.ndb
   phish.ndb
   rogue.hdb
   sanesecurity.ftm
   scam.ndb
   spamimg.hdb
   winnow_malware.hdb
   winnow_malware_links.ndb
"
However, DO NOT do something like this:

ss_dbs="
   junk.ndb
   jurlbl.ndb
#   phish.ndb
   rogue.hdb
   sanesecurity.ftm
#   scam.ndb
   spamimg.hdb
   winnow_malware.hdb
   winnow_malware_links.ndb
"

Instead, if, for example, you do not want to use the phish and scam databases, remove them from between the quotes, as follows:

ss_dbs="
   junk.ndb
   jurlbl.ndb
   rogue.hdb
   sanesecurity.ftm
   spamimg.hdb
   winnow_malware.hdb
   winnow_malware_links.ndb
"

As commenting them within the quoted section will only cause you problems and annoy the Sanesecurity rsync mirror site operators and possibly get your site added to the blacklist.

Ignore this advice at your own peril, and risk being blacklisted from any and all Sanesecurity signature database updates.

Regards,

Bill
