MSRBL-SPAM.Meds.35.UNOFFICIAL

[Kalimari]

Since yesterday @ 2.30 (GMT) clamav rules updated MSRBL-SPAM.Meds.35.UNOFFICIAL, which has stopped virtually every single in bound message since. Ran updates/etc, still no good and messages blocked. Deleted the matching (last) line in /var/clamav/MSRBL-SPAM.ndb and set chattr +i /var/clamav/MSRBL-SPAM.ndb until the problem is resolved. Any one else having problem with this clamav sig?

[Kalimari]

In an effort to locate the source of the issue, took a look at /usr/bin/clamav_updater.sh and get_update MSRBL-SPAM.ndb http://www.atomicorp.com/signatures/clamav/msrbl/ is the source so commented that line and reset file permissions chattr -i /var/clamav/MSRBL-SPAM.ndb (cron was complaining about changing ownership of `/var/clamav/MSRBL-SPAM.ndb').

We don't use that cronjob or script anymore, so you should disable it. ASL is also not setup to download that rule family, and I want to say we dropped it at least a year ago (the MSRBL project doesnt seem to have updated its rules since 2010).

OK, thanks. Never set it up manually (been running ASL for years) and have been upgrading as major versions came along. How best to remove? Delete /etc/cron.hourly/freshclam and /usr/bin/clamav_updater.sh and everything from /var/clamav? Why wasn't this handled as part of the ASL upgrade which
replaced the cron/script mechanism?

[Kalimari]

Have the following rules in /var/clamav/ - some of which should be kept and some deleted?

Assume /etc/cron.hourly/freshclam is OK to keep?

[faris]

You have the same old stuff left over from ages ago as I had on most of my systems before I removed it a year or so ago.

Keep the following:

Code: Select all

ASL-blacklist.ldb
ASL-h.ndb
ASL-honeypot-hex.ndb
ASL-honeypot.hdb
ASL.hdb
ASL.ldb
bytecode.cld
daily.cld
main.cvd
mirrors.dat
safebrowsing.cld

And in case of finger trouble, do a freshclam immediately afterwards.

[Kalimari]

Many thanks faris removed those files (and daily.cron) ran freshclam and all is good.
