In honor of this week’s security conference triple header of Black Hat, Defcon, and BsidesLV, we thought it pertinent to highlight some of the best and brightest infosec pros in the business – some of whom are long-standing veterans who deserve more attention, and some are emerging influencers we should all be paying attention to.

We privately surveyed a broad spectrum of thought leaders in the field of security and risk management and asked them to recommend candidates in three general areas – Defenders, Educators, and Hackers.

Two weeks ago we featured The Defenders and then last week we followed up with The Educators, and the response from the security community was astounding. This week it’s time to recognize some of the leading hackers in the field – yes, the hackers – because even though the mainstream media gets it wrong every time, hacker is not a derogatory term.

These are the pros who do something really important, and they do it well: They break stuff. When they break stuff, they write about it, they disclose it to those who can fix the vulnerabilities, and they help make all the technology everyone takes for granted more secure.

Hackers are the catalysts for innovation.

Please note that this is not an attempt at ranking these individuals, as the finalists are simply presented here in alphabetical order, and we also realize the list is far from being all-inclusive.

With the caveats aside, let’s give kudos to The Hackers!

Mo is renowned by his admirers as a first rate security analyst, and a genuinely nice guy with a passion for knowledge who really enjoys getting involved with the security community, such as speaking on the rookie track at BsidesLondon this year. Those who have worked with Mo say that he is a very dedicated professional with a wide variety of talents, as well as being extremely self-motivated. His skills make him one of those security pros who can adapt rapidly to a variety of work conditions. Mo is known for being technically astute, hard working and for having an inherent knack for analytics. Expect to see more from Mo on the conference front now that he has taken the plunge. Editor’s Note: Mo really would have been better suited for the Educator’s list for his focus on security awareness, and the error was pointed out to me post-publication. Apologies Mo!

Daniel BorgesDan Borges, Penetration Tester at AppSec Consulting

(@ezs33d)(LinkedIn)(Personal Website)(Hacking and Forensics 101)

First off, Borges just initiated his Twitter account, so click the link above and give him a follow so he doesn’t look like such a n00b – and join the Hacking and Forensics 101 group on Facebook that he runs, one of the most informative on the platform for infosec pros – linked above as well. Borges is an up-and-comer who is extremely passionate about both computer science and information security, and this shows up in the quality of his work. When he sets his mind to a project, he persists until he reaches a level of perfection beyond what is required, if only to satisfy his own work ethic.  Borges is a web application and network penetration tester who conducts full spectrum testing of network infrastructures and web and mobile applications, including high quality blackbox testing and full source code reviews. Borges has installed and managed IT systems including LDAP, Database, Wiki, Forum, VoIP, CCTV, and Virtual Servers running a myriad of Linux and Windows penetration testing tools. Borges is definitely one to keep your eye on.

(@ethicalhack3r)(LinkedIn)(Personal Website)

Dewhurst is another talented upstart with experience is in black box web application security assessments, penetration testing, social engineering, and secure software development, as well as presenting and leading workshops at local ‘geek meets’, OWASP chapters, and at BruCON. Dewhurst is noted for his work on the Damn Vulnerable Web Application (DVWA) project, where security professionals can test their skills and tools in a legal environment in order to help web developers better understand the processes of securing web applications. Dewhurst is not in security for the notoriety, he simply does it because he is passionate about the work, and it shows.

Matt ErasmusMatt Erasmus, System Engineer at Norman ASA

(@undeadsecurity)(LinkedIn)(Personal Website)

Erasmus is said to be a hacker to keep an eye on. He is a South African penetration tester living in Norway who is known for being creative, willing to walk the extra mile on a project, and able to find that vulnerability you never thought you would have. Erasmus is described as a low-key person who may fool you into thinking he is not as skilled or knowledgeable of a security professional as he really is. Erasmus is a someone who very well may show up on the future agenda of a Black Hat conference, as he is willing to share his passion for security and deep technical knowledge. Keep an eye out for him.

Barnaby JackBarnaby Jack, Director of Embedded Device Security at IOActive

As this article was being written, news broke that Barnaby Jack had passed away quite unexpectedly, sending a shock-wave through the security community. Though already quite well known for his amazing ATM and medical device hacks, Jack could still easily be described both a rising star and a gem in the field. His untimely passing is a major blow to the security community, and it would be difficult if not impossible to find any equivalent loss in this industry, as Jack was truly a one of a kind. Aside from his groundbreaking vulnerability research, Jack was also known for his passion, his humble and unpresuming nature, and his fun-loving personality. His scheduled talk at Black Hat this week has quickly been re-purposed as an impromptu memorial and celebration of his life and accomplishments, with friends and family putting together a slideshow and sharing the warmest of memories for our friend and comrade. Friends of Jack have also initiated a fund in his honor, with some proceeds going to assist his family with funeral arrangements, and the bulk being given to The Barnaby Jack HacKid Fund, which will underwrite a safe, innovative, creative community for future hackers. We encourage you to donate today and in the future to help preserve Jack’s legacy and innumerable contributions to the security field.

McJunkin will be at Defcon and BSidesLV this week, doing the Red Cell-Blue Cell competition. McJunkin will also be teaching a series of information security classes to students at Southern Oregon University this fall, with special focus on the Collegiate Cyber Defense Competition, which SOU will be competing in for the first time in 2014. McJunkin has a lot of potential in the security realm but is still fairly unknown – hopefully this mention will help change that.

Xavier MertensXavier Mertens, Security Consultant

(@xme)(LinkedIn)(Personal Website)

Mertens was pitched as being “a European guy who is gaining fame for his awesome post-conference roundups. He captures the essence of a conference really well.” Mertens says he enjoys doing both offensive and defensive security to better protect assets because we need to understand how attackers operate in order to better defend against their tactics. Mertens’ expertise includes pentesting, social engineering, security audits, incident management, security architectures, SIEM and security visualization. A security blogger at night, Mertens is also co-organizer of the BruCON, and applies his innovative thinking to staying ahead of the evolving threat landscape.

Fabienne SerriereFabienne Serriere, Systems Engineer at SysEleven

(@fbz)(LinkedIn)(Personal Website)

Serriere is known as a real mover and shaker in the hardware hacking world, and is also a fervent social activist who describes herself as a “futurist at heart, but one who believes that the future should be present during the present.” She divides her time between hardware hacking and wide variety of personal interests not connected to security, though all of which could fairly be described as being quite innovative. She has written for the Weblogs network (now owned by AOL) since 2005 and for numerous other blogs on topics including hardware hacking and open source technology. She appears to be ever gaining momentum, and we can expect to see some impressive work from Serriere in the years to come.

Kathryn S.Kat Z. Sweet

(@TheSweetKat)(Personal Website)

While Sweet’s upcoming presentation at BSidesLV on the 3D printing of – well, lets just call them intimate fulfillment devices – might be considered NSFW, some renowned infosec influencers believe she is the embodiment of what a ‘hacker’ really is – taking technology and tinkering with it to make it her very own. Not your typical hacker-type, Sweet has a degree in gender and women’s studies, an academic path that she says gave her the opportunity to compose numerous and heavily researched papers about, er… those personal devices.  The provocative nature of her interests and forthcoming BSidesLV presentation are illustrative of her dedication to independent thought, a valuable trait for a hacker. We should expect big things from her going forward.

picKen Westin, Security Researcher and Creative Technologist

(@Kwestin)(LinkedIn)(Personal Website)

Ken is a security researcher at Tripwire with 14 years experience building and breaking things through the use/misuse of technology, and is the Founder of the popular GadgetTrak cross-platform mobile security and data protection software, which he first launched in 2007. Westin’s technology exploits and endeavors have been featured in Forbes, Good Morning America, Dateline, New York Times, The Economist, and Portland Business Journal included Westin in their 2013 “40 Under 40”.

Westin is often sought out as a subject matter expert in areas of cyber security, privacy and surveillance, and we can expect to see more from him in the way of innovation in the years to come.

Leron ZinatullinLeron Zinatullin, Information Security Expert

(@le_rond)(LinkedIn)(Personal Website)

Zinatullin, a recent presenter at BSideLondon, resides in the UK where he is finishing his Master’s degree in infosec and apparently already has a job lined up at KPMG. He is described as being one of those really hard working guys who will no doubt end up making a good name for himself in the field. While he is at first glance a business-oriented security specialist with experience in legal and regulatory compliance, GRC and privacy issues, he has identified security gaps for a large energy company and was responsible for implementing required changes to the infrastructure. Zinatullin has conducted numerous vulnerability, threat, and risk assessments, as well as designing layered information security system architectures. While not your typical hacker type, he applies his vulnerability assessment skills to breaking and fixing, and that is the the mainstay of any good hacker.

We know there are many, many more out there – so who would you suggest? Make your recommendations in a comment below, or shoot me an email at afreed at tripwire dot com and we can include them in a subsequent article. Cheers all!

Editor’s Note: A special thanks to the many infosec pros – and you know who you are – who helped us identify these fine defenders and put this list together – we appreciate your time, input, and above all else your candor. Additional data gleaned from publicly available LinkedIn profiles.
