Usually it's the moment where you have to try to find something new...and then make sure it match. But seeing this :

Invitation to register
I just tried...but the IP of that domain was already familiar

At that exact moment I knew almost for sure what was all this about and why first IP was familiar.
Note that going on : www.toptonic .bz you see


And that was familiar too.

I was hoping not finding evident link..but so obvious that i can't ignore....see later...

Silence Exploit Kit - Exploit - My Thread
Silence Exploit Kit - Exploit - My Stats.
Empty...no active thread...but what is worth noticing is that it's a Popup
And that does not fit with the other part of the user interface (but perfectly stick to my deep feeling).
Silence Exploit Kit - Scan Service
Silence Exploit Kit - Crypt Service

Silence Exploit Kit - Traffic Service
Silence Exploit Kit - Buy Services

And now...Here was my feeling. All this is just Blackhole subletting ! 
5.45.179.44 is an IP of a bad bad range that I associate to a Blackhole that appear on my radar (but was surely operationnal before) on the 2013-05-08  with landing : /transport/posted-sorts.php on TCP port 5555 of IP 5.45.176.207

Checking the server a little I was able to figure out that the mothership (that I usually never disclose - but in that case that serve the explanation) was : 174.120.184.68
Original config was like :

bhadmin : progress
bhstat : service
links : transport
library : fatal
data : continuous
files : locked

We could think it's a shared server...but one user of the forum posted his stats :

Silence...euh Blackhole Exploit Kit Stats with some cosmetics.
And the popup embed in fact the "bhstats" (see the scroll bar).
While writing : bhstat = service


And that also explain why this Blackhole is so active. I have seen at least 46 distinct file threads in one month. Few blackhole have such a "thread activity". And also a good number of reverse proxy.
Right now :

Positive IP to "The Silence" Blackhole
in  5.45.176.0/21
On the mother range :

Positive IP to "The Silence" Blackhole in his mothership Range...
70...oh  noze...Jo !
This one is also the same owner :
174.122.75.162

In my opinion 2 real server. One by softlayer with (at least) 5 ips, and one by BKGV with two range acting as a proxy.


For the activity you can see on Urlquery :

Some files gathered from this Blackhole - http://pastebin.com/xXaV1Hae :
Files : http://goo.gl/m8qiC (Owncloud)
Some payload from BH EK /transport/
Won't spend time in studying that. Some Betabot, UmbraLoader, Bitcoin miner. But we could have guess based on the forum and :
Comment about "The Silence"
And in fact...we could have guess more far earlier...

The Silence trying to Rent his Rented Blackhole
At that time someone asked him, and it's still a valid question:

Question about his blackhole subletting back in november
We could have a lot of smile reviewing the 29 pages (2013-06-01) thread...but let's finish that.

"this pack really is the best of the best when it comes to exploit packs" - The Silence

And now embarrassed silence...

For those who jump straight from the beginning : this is a Subletting of Blackhole Exploit Kit. A Fancy front-end to interact with the owner (sic) of the  BH EK that often come on tcp 5555 (but not always) with /transport/ as thread folder. Let's forget about that :)

<edit2 2013-06-02 22:00> Seems the written explanation is not really good so i added a small illustration.


Illustration
(hope will reply to questions)

In fact thinking about it, it's more like a frontend to "The Silence" who is doing manually all modification on the blackhole. I guess sometimes you have to wait few hours before getting your thread.
