Avast does not detect Blackhole site

Actually, the above fakes the first appendChild (inside a try) and does an eval appendChild.

Too many bells ringing here to alert : http://urlquery.net/report.php?id=84145
Also a trojan downloader for Zeus on that domain…see Malware Domain List
and I see suspicious content after the < /html> tag - a padding to disable MSIE and Chrome friendly error page →

thanks! pol my friend :slight_smile:

To explain one of the snort rule alerts a bit more:
in this example the ‘hcp_vbs.php?f=’ part of the URL is known to be part of the ‘Black Hole Exploit Kit’.
And this was one of the bugs abused on that site: description of exploit → https://bugs.php.net/bug.php?id=35360
because you see a snort rule alert given for this, e.g.:
BLACKLIST URI possible Blackhole post-compromise download attempt - .php?f=
this will deliver various malicious PDF files to a user/victim,

How about this one: http://urlquery.net/report.php?id=84805

Avast blocked the resource itself, and the Trojans also have in the database.

And this is what is downloaded:

Thanks for checking Dim@rik, one less to worry about then.
Hopefully we get detection for all of them, well at least that is why we are reporting,

For this one we have 4 av detections and we have avast IP block via the avast Network shield!

Downloading two samples, both are determined.

Hi Dim@rik,

It is good to know that avast is one of the few av that detects the pony downloader from that site as Win32:Zeus-A [Trj] . Mostly pony downloaders are configured to POST stolen FTP credentials to certain drop zones, then grab Gameover Zeus banking trojans from determined locations, and fraudulent site engaged in Identity Theft, Phishing, Money Mule,
