CVE-2015-8651 (Flash up to 20.0.0.228/235) and Exploit Kits
While other exploit kit are struggling to keep up with Angler (none is firing CVE-2015-8446 , maybe because of the Diffie-Hellman protection on Angler's exploits ),
- Nuclear / Magnitude and Neutrino last exploits are from October (CVE-2015-7645)
- RIG and Sundown are relying on July exploits (Hacking Team's one - CVE-2015-5122)( all have the IE CVE-2015-2419 from august)
Angler has just integrated CVE-2015-8651 patched with Flash 20.0.0.270 on 2015-12-28
Angler EK : 2016-01-25
The exploit might be here since the 22 based on some headers modification which appeared that day.
It's not yet pushed in all Angler EK threads but widely spread.
Thanks Anton Ivanov (Kaspersky) for CVE Identification !
