Earlier today, Adobe published the security advisory APSA16-03, which describes a critical vulnerability in Adobe Flash Player version 184.108.40.206 and earlier versions for Windows, Macintosh, Linux, and Chrome OS:
A few of months ago, we deployed a new set of technologies into our products designed to identify and block zero day attacks. These technologies already proved its effectiveness earlier this year, when they caught an Adobe Flash zero day exploit, CVE-2016-1010. Earlier this month, we caught another zero-day Adobe Flash Player exploit deployed in targeted attacks.
We believe these attacks are launched by an APT Group we call “ScarCruft”.
ScarCruft is a relatively new APT group; victims have been observed in several countries, including Russia, Nepal, South Korea, China, India, Kuwait and Romania. The group has several ongoing operations utilizing multiple exploits — two for Adobe Flash and one for Microsoft Internet Explorer.
Currently, the group is engaged in two major operations: Operation Daybreak and Operation Erebus. The first of them, Operation Daybreak, appears to have been launched by ScarCruft in March 2016 and employs a previously unknown (0-day) Adobe Flash Player exploit, focusing on high profile victims. The other one, “Operation Erebus” employs an older exploit, for CVE-2016-4117 and leverages watering holes. It is also possible that the group deployed another zero day exploit, CVE-2016-0147, which was patched in April.
We will publish more details about the attack once Adobe patches the vulnerability, which should be on June 16. Until then, we confirm that Microsoft EMET is effective at mitigating the attacks. Additionally, our products detect and block the exploit, as well as the malware used by the ScarCruft APT threat actor.
