Jason Geffner
Jason Geffner joined Next Generation Security Software Ltd. in June of 2007 as a Principal Security Consultant. Jason focuses on performing security reviews of source code and designs, reverse engineering software protection methods and DRM protection methods, penetration testing web applications and network infrastructures, and developing automated security analysis tools.
Prior to joining NGS, Jason spent three years as a Reverse Engineer on Microsoft Corporation’s Anti-Malware Team, where his work involved analyzing malware samples, deobfuscating binaries, and writing tools for analysis and automation. Jason was the Security Research & Response owner of the Windows Malicious Software Removal Tool (MSRT). He chose which new malware families for the MSRT to detect and clean each month based on his analysis of the telemetry and trends of the underground malware community. Jason authored tens of thousands of malware signatures and dozens of malware analyses based on static and dynamic analyses of obfuscated binaries. His work on the MSRT helped hundreds of millions of Windows users each month keep their computers safe and secure. While at Microsoft, Jason was recognized for his reverse engineering skills and for his efforts to drive awareness of reverse engineering practices throughout the company by being given the formal job title “Reverse Engineer”; Jason was the only Microsoft employee with this title.
Jason holds several patents in the fields of reverse engineering and network security. He is a Program Committee member of the Reverse Engineering Conference (REcon) and of the International Conference on Malicious and Unwanted Software, is a regular trainer at Black Hat and other industry conferences, is often credited in industry talks and publications, and has been actively reverse engineering and analyzing software protection methods since 1995.
