CVE-2013-2465/CVE-2013-2471/CVE-2013-2463 integrating Exploit Kits -- jre7u21 CVE- jre6u45 and earlier




Two days after disclosure, CVE-2013-2465 is starting to be integrated in Exploit Kits.
What makes it "better" than CVE-2013-2460 (recently integrated in Private Exploit Pack) is that it's targeting all Java branch 6 (update 45 included)

<edit4> NB: Have been told that it crashes with jre6 <= 18  </edit4>

Here is it in
Styx "Kein Edition" :
(this is Styx, but that instance was named Kein in the past)

CVE-2013-2465 successful pass in Styx "Kein Edition"

<edit7> We'll refer to this exploit kit as x2o (based on the text we can find now in the landing), as long as we do not know it's official name. This really looks like a "Redkit Light" (as @EKWatcher wrote) </edit7>

Did not spend time to understand why. Seems it was "fixed" 2 days ago.

(thx Timo for the Hints)
2013-08-27 Neutrino switch back to CVE-2013-2465...the reason is I would say that CVE-2013-2463 was not working for them (in fact no infection with it past 2 days).
</edit9>
<edit14 2013-09-06> It seems today CVE-2013-2463 is back in Neutrino and is working properly.
Waiting for confirmations before publishing </edit14>
