|
|
|
|
|
This module exploits a memory corruption flaw in Internet Explorer. This
|
|
|
|
|
flaw was found in the wild and was a key component of the "Operation Aurora"
|
|
|
|
|
attacks that lead to the compromise of a number of high profile companies. The
|
|
|
|
|
exploit code is a direct port of the public sample published to the Wepawet
|
|
|
|
|
malware analysis site. The technique used by this module is currently identical
|
|
|
|
|
to the public sample, as such, only Internet Explorer 6 can be reliably exploited.
