CVE-2015-0313 (Flash up to and Exploit Kits

Reported by TrendMicro (2015-02-02), fixed with Adobe Flash Player, the code to exploit CVE-2015-0313 has been introduced in Hanjuan Exploit Kit at beginning of december 2014  according to Malwarebytes

Hanjuan is the name chosen by @MalwareSigs for an Exploit Kit he first reported on 2013-10-14.

I would say this pastebin from 2011 is already showing a traff/stats tuple from Hanjuan (or an ancestor).

On the 2015-02-03, I captured a Fiddler of the live chain exploiting CVE-2015-0313 as spotted by Trendmicro in their telemetry.

Full chain to bedep via CVE-2015-0313 - 2015-02-03

So despite what Dailymotion is claiming here , their USA users were indeed affected by this "0day".
But this can happen to any company showing ads. A web advert is often the result of a long chain of trust...(as software/drivers in operating system...one fail, everyone fall).

The problem for me in that case is that Engage:BDR (delivery.first-impression.com) was totally aware that this specific customer (Caraytech group - e-planning.net ) was conditionally redirecting users to Hanjuan Exploit Kit.
I sent them a warning on 2014-12-12 and after not far from 80 mail exchanges till 2014-12-28, I decided to stop communicating with them as they were litigious and obviously not willing to stop the involved advert IDs. There were also many tweets from @BelchSpeak illustrating the issue.

You may now understand that tweet which is not exactly in line with my timeline.

(Note : I might ask for some help in case Engage:BDR decides to go the legal way against me because of this post - The irony : being more afraid from "legit" company than  from guys converting coffee in malware activity)

This exploit without a surprise is now being rolled in other Exploit Kit and again no surprise Angler is the first one.
