Description: 

An Adobe Flash Player zero-day vulnerability has been discovered by Trend Micro which could allow for remote code execution. This exploit has been confirmed by Trend Micro to be in use in the wild as part of malvertizing attacks and appears to be part of the Angler Exploit Kit. Please note that Adobe has acknowledged this vulnerability and is currently working on a patch to be released sometime during the week of February 2nd. ITS CSOC will continue to monitor this vulnerability and update accordingly. Trend Micro discovered one affected domain in its investigation. Dailymotion[dot]com, is a popular video sharing site which, after a series of redirects, takes the user to hxxp://www.retilio[dot]com/skillt[dot]swf. Due to the similarities in obfuscation techniques and infection chains, it is believed that this vulnerability is included in the Angler Exploit Kit. Successful exploitation could result in an attacker accessing confidential data or compromising processing resources on a user's computer.
