md5sum: 04f34a0597ab21ce25f4fc6bc84cc5d4

I see this on the server side and the hash is assigned to an analyst to take a 
look.

Also, on the web form when submitting false positives there is a

might get some kind of notification when your sample had been processed,
but I have never received any notification for any of the samples I've
submitted. What is that check-box for?


I don't know what's going on. It seems that ever since the Cisco buyout the 
quality of ClamAV has disintegrated really fast.

I am always submitting samples from my email and blog spam to VirusTotal, 
ClamAV, and CRDF. VirusTotal often shows tons of failures, often more than half 
of the major antivirus products but never ClamAV, and then I submit to CRDF, 
who do their own automated VirusTotal scans and mark them as malware right away.

ClamAV, however, marks them clean for weeks (unless you use CRDF's signatures) 
and often they are never marked malware.

In fact, I have a list of MD5s of 600 MB worth of malware from a game hack 
site spammed to my blogs. I sent e-mails to ClamAV saying I had the MD5s and 
files but received no response. I wound up deleting the files because only two 
were marked as malware, and by CRDF's signatures, not by ClamAV's.

(I still have the MD5s list if anyone wants me to post it on the message board)

Good thing I only use Linux now, where the effectiveness of antivirus software 
isn't too important. I just wish ClamAV developers were more attentive to their 
product, which they haven't been since Cisco bought Sourcefire.

I’d disagree here.  In fact, we’ve only added to the team since the Cisco 
purchase.  We’re currently working on a better way to report false positives, 
so hopefully we’ll see some resolution to the issue soon, but by all means, if 
you have FP reports, please report them via the website and we’ll take a look 
at the issue.

As far as reports of new malware, again, the website is the best place to send 
them, however, for bulk uploads, like the website says, it’s best to contact us.

Where did you send emails to us that we missed?  Maybe we’re having a server 
problem that I haven’t seen yet and we need to get that fixed.

If people would like to contribute their own signatures to the ruleset, we’d be 
happy to take a look at that as well:

Hi there,

There's a distinction between adding to the team and improving it.

Seems to me I've been reading the same old complaints here on the
ClamAV mailing list for years now.

Good job I only use ClamAV because of the third party databases like
Sanesecurity.

And it would *really* help if the people who use this list learn how
to write to mailing lists.

I most likely sent the list of MD5s (actually they were SHA256sums) as an 
attachment to azidouemba-AT-sourcefire-D0T-c0m

I've just sent the attachment to jesler-AT-cisco-D0T-c0m

I actually haven't had a false positive in a very long time, but lots of 
undetected malware which fail VirusTotal scans for all the major brands. Like I 
said CRDF third-party signatures detect the malware an hour or so after you 
submit the files. I've been also sending them to ClamAV, no more than 2 per 
day, using the clamsubmit tool.

[clamav-users] false positive sample

2014-08-22 Thread Dan McDaniel

I submitted a false positive awhile ago -- probably back in May. It
hasn't been fixed yet. Should I submit it again?

Also, on the web form when submitting false positives there is a
check-box that says notify me. It would seem to imply that you 
might get some kind of notification when your sample had been processed,

but I have never received any notification for any of the samples I've
submitted. What is that check-box for?
