Thanks Luca for investigating the false negative reports and submitting them to 
our malware research team.  These reports really help, even if you don't 
necessarily get feedback on the reports.

Kind regards,
Micah

Please update the version of clamsubmit you are using.  You are several 
versions behind.

Luca

It's possible that some of the failure to detect is due to your using an 
outdated version of ClamAV. Some signature only work with more recent versions. 
You should probably focus on upgrading before submitting any undetected samples.

Re: [clamav-users] Question about sending sample process

2018-11-06 Thread Arnaud Jacques 

Hello Luca,

If I remember well, clamsubmit only works since versions 0.100.x of 
ClamAV. It seems you are still using version 0.99.4.



Question 1 - Is this process correct to send samples?


Yes it it.

Question 2 - How much time is required to validate a sample and get 
the A/V db updated? Days? Months?


Depending of many things on ClamAV team side, it can take just a few 
hours, or days, or ... never.


- Actually a scan of all the stuff retrieved from that website have 
this results while I expect to have a 100%


If you expect 100% detection, please use at least the last version of 
ClamAV.

And some 3rd party signatures can help to get full detection :

[clamav-users] Question about sending sample process

2018-11-06 Thread Luca Moscato 
Hi everyone, one of our customers notify us that the AV we use (clamav 
of course) does not detect some of malware downloadable from das malwerk 
usued for testing.


Pretty strange situation, so we decided to download all malwares from 
that site and send as a sample using command line interface


[luca@amazon-ami:~]$ clamsubmit -n 
/home/luca/malware/d77aca7d-f9f1-11e7-b482-80e65024849a.file -N luca -e

Question 1 - Is this process correct to send samples?

Question 2 - How much time is required to validate a sample and get the 
A/V db updated? Days? Months?


Some notes:

- I'm using Amazon linux and clamav version available in amz linux repo, 
db should be updated with freshclam
