clam-punch's Introduction

clam-punch

A highly curated set of signatures for ClamAV 0.99+. MiscreantPunch099-Low.ldb is the marquee ruleset here, is optimized for multiple engines, and uses the newest features. This ruleset is updated often, and would be considered "Low" FPs.

There are several other rulesets here I would consider looking into adding as well. More info can be found in: https://github.com/wmetcalf/clam-punch/blob/master/MiscreantPunch-Info.txt

If you are running ubuntu and you want to run these.. Edit the file /usr/share/clamav-unofficial-sigs/conf.d/00-clamav-unofficial-sigs.conf

and add the line..

add_dbs="https://raw.githubusercontent.com/wmetcalf/clam-punch/master/MiscreantPunch099-Low.ldb"

if you want to run the single byte EXE XOR sigs also add

add_dbs=" https://raw.githubusercontent.com/wmetcalf/clam-punch/master/miscreantpunch099.ldb https://raw.githubusercontent.com/wmetcalf/clam-punch/master/exexor99.ldb " Then

sudo -u clamav /usr/sbin/clamav-unofficial-sigs

We will no longer be updating the miscreantpunch.ldb file only the 'MiscreantPunch099-Low.ldb' files which utilizes the 0.99 features.

Clarification on databases

Hi

Please could you clarify the following, as I would like to include them in the latest version of the clamav-unofficial-sigs

MiscreantPunch099-Low.ldb, low false positive for usage with clamav 0.99+ (yara)

miscreantpunch.hdb, false positive is low, medium, high ? Only use for clamav 0.98 and lower?

miscreantpunch099.ldb, false positive is medium, high ? can this be used with MiscreantPunch099-Low.ldb ?

Thanks

Differences MiscreantPunch099-Low.ldb and miscreantpunch099.ldb ?

Hi.

I am using miscreantpunch099.ldb for some time now and I recently discovered you added new ldbs, specifically MiscreantPunch099-Low.ldb

Which should I use (for a mailserver), what are the differences?

Is the MiscreantPunch099-Low.ldb just a Low FP version of miscreantpunch099.ldb?
I never had FP problems with miscreantpunch099.ldb, so should I stick with miscreantpunch099.ldb then?

Thanks for your work, it really is appreciated :)
