Thomas Lim is the Founder and CEO of COSEINC and SyScan. Previously as the head of IT Security in one of the largest IT services companies in Singapore, he was highly disappointed with the so-called Security seminars organised by the various vendors to be nothing but a sales and marketing pitch.

In 2004, he founded SyScan, a true-blue technical-based and vendor neutral IT security conference with a strong emphasis on cutting edge security research. Today, in its 8th year, SyScan is one of the most recognised security conference in the security community.

As for COSEINC, this is the only privately based and funded security research company in Singapore, which became highly prominent in the security community after the publication of "BluePill" - the first hardware based VM rootkit back in 2006.

Alex is coauthor of Windows Internals 5th edition.  He teaches Windows OS internals to Microsoft employees and other organizations worldwide. 

He is the founder of Winsider Seminars & Solutions Inc., specializing in low-level system software for administrators and developers. Alex was the lead kernel developer for ReactOS, an open source clone of Windows XP/2003 written from scratch, where he wrote most of the NT-based kernel.

Alex's experience in OS design and kernel coding dates back to his early adolescence when he first played with John Fine's educational OS, Kernel, and Boot Loader code. Since then, he has been active in the area of NT kernel development, offering help and advice for driver developers, as well as in the NT reverse engineering and security field, where he has published a number of articles and source code, such as documentation for the Linux NTFS project, extensive papers on the Visual Basic Metadata and Pseudo-code format, and NTFS Structures and Data Streams. In the last three years, he has also contributed to patches and development in two major commercially used operating system kernels.

Stefan Esser is best known in the security community as the PHP security guy. Since he became a PHP core developer in 2002 he devoted a lot of time to PHP and PHP application vulnerability research. However in his early days he released lots of advisories about vulnerabilities in software like CVS, Samba, OpenBSD or Internet Explorer. In 2003 he was the first to boot Linux directly from the hard disk of an unmodified XBOX through a buffer overflow in the XBOX font loader. In 2004 he founded the Hardened-PHP Project to develop a more secure version of PHP, known as Hardened-PHP, which evolved into the Suhosin PHP Security System in 2006. Since 2007 he works as head of research and development for the German web application company SektionEins GmbH that he co-founded.

In 2010 and 2011 he got a lot of attention for presenting about iPhone security topics and supplying the jailbreaking scene with an exploit that survived multiple updates by Apple.
