Ivan Krstić is a software architect and researcher currently on leave from Harvard University. Until recently, he worked as director of security architecture at One Laptop per Child, an education non-profit that aimed to produce a $100 laptop for children in the developing world. Prior to that, Ivan served as director of research at the medical informatics laboratory of a European children's hospital, tackling infrastructure and security problems in wide-scale digital healthcare.

Ivan is deeply involved in open-source and free software, co-authored the best-selling Official Ubuntu Linux Book, and specializes in architecture and security of large distributed systems. He has consulted on both matters for some of the largest websites on the Internet. Described by Wired magazine as a "security guru", in 2007 the MIT Technology Review named him one of the world's top innovators under the age of 35 for his work on the OLPC security platform, Bitfrost. Recently, eWEEK declared him one of the top three most influential people in modern computer security, and one of the top 100 in all of IT.

Joakim Sandström is the founder and Chief Technology Officer of nSense. A typical day at the office includes vulnerability assessments for the Nordic financial market and developing automated vulnerability assessment tools.

Adam Laurie is a freelance security consultant working the in the field of electronic communications. He started in the computer industry in the late Seventies, working as a computer programmer on PDP-8 and other mini computers, and then on various Unix, Dos and CP/M based micro computers as they emerged in the Eighties.

He quickly became interested in the underlying network and data protocols, and moved his attention to those areas and away from programming, starting a data conversion company which rapidly grew to become Europe's largest specialist in that field (A.L. downloading Services). During this period, he successfully disproved the industry lie that music CDs could not be read by computers, and, with help from his brother Ben, wrote the world's first CD ripper, 'CDGRAB'. At this point, he and Ben became interested in the newly emerging concept of 'The Internet', and were involved in various early open source projects, the most well known of which is probably their own ”Apache-SSL” which went on to become the de-facto standard secure web server.

Since the late Nineties they have focused their attention on security, and have been the authors of various papers exposing flaws in Internet services and/or software, as well as pioneering the concept of re-using military data centres (housed in underground nuclear bunkers) as secure hosting facilities.

Adam has been a senior member of staff at DEFCON since 1997, and also acted as a member of staff during the early years of the Black Hat Briefings, and is a member of the Bluetooth SIG Security Experts Group and speaks regularly on the international conference circuit on matters concerning Bluetooth security.

He has also given presentations on forensics, magnetic stripe technology, InfraRed and RFID. He is the author and maintainer of the open source python RFID exploration library 'RFIDIOt', which can be found at http://rfidiot.org.

Kimmo Kasslin is working for F-Secure Corporation as a Research Manager. He joined F-Secure in 2005 and was part of the team that created BlackLight, one of the worlds first anti-rootkit engines. Kimmo is a known researcher in the field of Windows rootkits and modern stealth malware.

He has made presentations in VB and AVAR conferences. His latest research interest has been in the emerging threat of kernel-mode malware.

Nishad Herath has been playing reverse engineering for the better part of the last two decades. So much so that he is utterly and completely addicted to his passionate obsession. Over the years, he has been waltzing around in security, DRM and general reverse engineering circles mostly. In his adventures, he has worked closely with ISVs, private sector enterprise as well as government and law enforcement agencies.

These days, Nishad spends most of his time doing research on interesting areas of technology while assisting his clients in (hopefully) making the world a better place. When he is not doing that, he can be seen chipping away at his Tai Chi Chuan gongfu or entertaining his two little troublemakers as they get into all kinds of mischief.

A year ago, Jani discovered that these methods are now being used for black box malware analysis. That motivated him to study a little but further how he might be able to help malware analysts in their work.
