Hello
Few days ago I discovered site with some information about VMware Update Manager. I had a problem with it and I was searching for solution.
This site is www.bourgelat.net/cannot-patch-definitions-vmware-19988
I have PA with all licences but PAN software doesnt detect any bad traffic
I asked PAN to change categorization to malware site, but today I got email : New category: computer-and-internet-info
This site still trying to hurt Your computer, and PAN doesnt responds to it - is it OK?
I have security policy with thread prevention/av - but it doesnt stops it, hopefully my Symnatec Endpoint protection detecting it and blocking.
You can try to open www.bourgelat.net - this isn't https so in my opinion PAN should react in some way to this traffic.
Do You agree with me?
How it's possible when IE 10 with default configuration recomends to not enter to this site while PAN recategorization is computer-and-internet-info ?

small update, www.bourgelat.net is classified as malware site by BightCloud Service, and it's blocked if You are blocking access by url filter (block malware sites) but if you are using PA url database you are under risk!

My symantec endpoint pretection is detecting that this site try to attact my computer using "red export kit redirect" now.
04-17-2014 12:45 PM
Are you referring to this threat Web Attack: Red Exploit Kit Redirect: Attack Signature - Symantec Corp. ?
If yes then --> CVE-2009-4324
CVE-2009-4324 is covered with nine Threat ID's
Are these nine Threat ID's all covered in your Vuln. Protection Profile ?
BTW, www.bourgelat.net/cannot-patch-definitions-vmware-19988 does not seem to be accessible at all
04-17-2014 01:22 PM
I can't verify it now, but probably - yes.
Today "www.bourgelat.net/cannot-patch-definitions-vmware-19988" isn't accessable but please try with www.bourgelat.net Please try with it.
I will check my security rules, but I'm sure that I blocing medium and critical threats.

I don't see anything threatening on www.bourgelat.net
04-17-2014 01:37 PM
Although a google search for "www.bourgelat.net malware" shows very suspicious results...

Here You are report from today (SEP):
is it a false positive?

Slawek,
We deal with situation by having two custom URL categories:
1. Temporary-Blocked = this allows you to immediately block it while you wait for a reclassification request to be processed by Palo Alto.
2. Custom-Blocked = This allows you to override the Pan-DB or Brightcloud category. Additionally you can use it to block parts of an otherwise good website.
Hope this provides a way to react quicker. It works quite well for us.

Hi Gafrol
In my opinion I have all this 9 CVE covered. Security policy has:
And "strict" thread prevention profile is a default one:
I try today to open "bourgelat.net" and again only SEP blocked this traffic.

Hi Hitsec
Thank for clarification, but the clue is that PA refued to change classification to malware sites.
04-24-2014 08:01 AM
Slawek,
I fully understand and have experienced the same situation.

Problem reported to support, I will let You know if we made any progress.
Could someone verify using other NGF than PA and endpoint protetection than Symantec that this site try to hurt your computer and post small report of tests?
Regards
Slawek
