Exploit Kits haven’t disappeared, they’ve simply moved to Microsoft Office. Traditional Exploit Kits (EKs) have the ability to fingerprint and compromise web browser environments, but with the advent of sandboxing and advanced security measures, there has been a shift toward using the Microsoft Office environment as a primary attack surface. Document Exploit Kits (DEKs) leverage DCOM, ActiveX controls, and logic bugs to compromise machines by packing multiple exploits into a single file.
This talk will provide an in-depth overview of the vulnerabilities and exploitation techniques used by the ThreadKit and VenomKit documents to spread well known malware families, and how they are being used in targeted attacks.
