Julia Wolf

CVE-2011-3402 is well known as the Windows Kernel TrueType [Font]
0-day used in the "Duqu" attack(s). Recently this exploit has begun to
appear in several crimeware exploit kits... Actually, not merely just the
exploit, but the *entire* font file used by Duqu, now being harnessed to
infect a large population with malware. This talk will mostly be an
extremely low-level walk-through of the font program within this TrueType
font, which is used to manipulate the Windows Kernel into executing the
native x86 shellcode.
