Carlos Cajigas has his heart fully invested in his work. Following the terrorist attacks on September 11, 2001, Carlos was inspired to pursue a career in law enforcement in order to combine his passion for computers with his sense of duty to protect victims of cybercrime and make the world a safer place. Today, Carlos has expanded his pursuits to include being an instructor and blogger, enabling him to share his knowledge and experience with others interested in pursuing a career in digital forensics.
A native of San Juan, Puerto Rico, Carlos began his career with the West Palm Beach Police Department in Florida, first as a police officer and eventually as a digital forensics detective, examiner, and instructor specializing in computer crime investigations. During his law enforcement tenure, Carlos conducted examinations on hundreds of digital devices, from computers and mobile phones to GPS devices, and served as both a fact and expert witness in the State of Florida. In 2013, Carlos taught mobile forensic courses in Latin America for the U.S. State Department's Anti-Terrorism Assistance Program.
Today, Carlos is a senior incident response analyst at IBM, where he is responsible for responding to computer and network security threats for clients located in North and South America. Carlos also teaches FOR408: Windows Forensic Analysis at the SANS Institute, where he brings his experience with law enforcement forensics and enterprise incident response to the classroom.
"My teaching philosophy is simple," Carlos says. "I strive to empower each student by developing their ability to conquer knowledge of a forensic technique, using demonstrations and the sharing of real-life applications and implications as to why a technique is important. I want my students to know which specific artifacts to analyze regardless of the tool chosen for the analysis."
Digital crime has increased dramatically in recent years, and hard drive sizes have expanded exponentially, greatly increasing the amount of cases and devices that need to be analyzed.
"The days of imaging and processing extremely large hard drives for hours before beginning analysis is a thing of the past," says Carlos. "Taking into consideration limited resources and manpower, today's examiners must be as efficient as possible in what we do and how we do it."
To help students overcome these challenges, Carlos shares techniques in his classes on how to directly target specific files and folders that can yield the biggest amount of answers in the least amount of time. "That way you can have answers within minutes rather than within hours," he says.
Carlos has been involved in hundreds of cases and helped obtain numerous convictions using many of the techniques he teaches in class. As an investigator, he gets great satisfaction knowing that he did his part in protecting victims. As a teacher, seeing students grasp his explanation of an artifact can be just as satisfying, knowing that he is preparing them for the challenges of the future.
Carlos holds bachelor's and master's degrees from Palm Beach Atlantic University in Florida, and has completed numerous training courses, including courses offered by Guidance Software (EnCase), National White Collar Crime Center (NW3C), Access Data (FTK), United States Secret Service, the International Association of Computer Investigative Specialists (IACIS) ,and SANS.
Carlos also holds numerous certifications in the digital forensics field, including EnCase Certified Examiner (EnCE), Certified Digital Forensic Examiner (CDFE) from Mile2, Access Data Certified Examiner (ACE), Certified Forensic Computer Examiner (CFCE) from IACIS, and the GIAC Certified Forensic Analyst (GCFA) and GIAC Certified Forensic Examiner (GCFE) from SANS. Carlos is a Florida Department of Law Enforcement (FDLE) certified instructor with experience teaching digital forensic classes. He is an active member of both the International Association of Computer Investigative Specialists (IACIS) and Miami Electronic Crimes Task Force (MECTF).
Carlos also maintains a computer forensics blog aimed at helping other digital forensic examiners use free open-source Linux-based tools to do their jobs. He hopes to develop and increase awareness in this area and believes that open-source tools can provide examiners with alternatives and/or supplement commercial software.
During his free time, Carlos throws his passion into his pursuit of designing and baking the best homemade pizza.

A self-described Mac nerd, Sarah Edwards is a forensic analyst, author, speaker, and both author and instructor of SANS FOR518: Mac Forensic Analysis. She has been a devoted user of Apple devices for many years and has worked specifically in Mac forensics since 2004, carving out a niche for herself when this area of forensics was still new. Although Sarah appreciates digital forensics in all platforms, she has a passion for working within Apple environments and is well known for her work with cutting-edge Mac OS X and iOS, and for her forensic file system expertise.
Sarah's dynamic classroom and presentation skills have been heralded by both her students and colleagues. She keeps students interested and engaged. Sarah has more than 12 years of experience in digital forensics, and her passion for teaching is fueled by the ever-increasing presence of Mac devices in today's digital forensic investigations. Given the complexity of most cases and the high probability that an OS X or iOS will be a part of an investigation, deep knowledge of these Operating Systems is crucial to ensure that forensic analysts grasp all the information required in a case and not omit valuable data.
"Apple devices will continue to grow in popularity, and digital forensic investigators and analysts must start paying more attention to them," Sarah explains. "Windows analysis is the base education in the field of digital forensics, and any additional skills you can acquire set you apart from the crowd, whether it is Mac, mobile, memory, or malware analysis."
Sarah has worked with federal law enforcement agencies on a variety of high-profile investigations in such areas as computer intrusions, criminal cases, counter-intelligence, counter-narcotics, and counter-terrorism.

For Phil Hagen, a career in information security chose him even before the movies War Games and Sneakers spurred his broader interest in the field. Phil has been captivated since the early days, working on information security projects since the mid-1990s, but networking grabbed his attention even before that.
"Since installing a 2400bps modem into an Apple //e around 1988, every computer I've used has been able to communicate with others," he says. "Of course the systems themselves are becoming more and more varied, making network analysis a critical component of the investigative process today."
Phil began his studies at the U.S. Air Force Academy's Computer Science Department, where he focused on network security and was an inaugural member of the computer security extracurricular group. He served in the Air Force as a communications officer at Beale AFB and the Pentagon. In 2003, Phil moved over to a position with a government contractor, providing technical services for various IT and information security projects.
Today, Phil's career has spanned the full attack life cycle - tool development, deployment, operations, and the investigative aftermath - giving him rare and deep insight into the artifacts left behind. Phil has covered deep technical tasks, managed an entire computer forensic services portfolio, and handled executive responsibilities. He's supported systems that demanded 24x7x365 functionality, managed a team of 85 computer forensic professionals in the national security sector, and provided forensic consulting services for law enforcement, government, and commercial clients. All of that brings Phil to his role today as the DFIR strategist at Red Canary, where he supports the firm's managed threat detection service.
Phil is also a certified instructor for the SANS Institute, and is the course lead and author of FOR572: Advanced Network Forensics and Analysis. This six-day course provides a hands-on curriculum to learn the skills necessary to perform investigations of network-based incidents, where the hard drives or memory of compromised systems are often missing.
"In each class, I take care to explain the relevance of the concepts to cases I've worked and scenarios I've encountered in the past," says Phil. "In FOR572, our classwork and hands-on materials are all taken from real-world experiences and cases. Our week in class is jam-packed and we deliberately focus our attention on adversary behaviors that have been actively observed in the wild."
Phil also spends time developing and maintaining the SOF-ELK distribution, a virtual appliance that is preconfigured with the ELK stack (Elasticsearch, Logstash, and Kibana). "This takes a lot of time investment, but it's very rewarding to hear from the DFIR community at large when they've used SOF-ELK in their own environments and cases to boost efficiency and effectiveness," he says.
Phil has always been a mentor and teacher at heart, and his relationships with former colleagues and students constitute one of his biggest sources of professional pride. "In my previous job at a large defense contractor, I was responsible for managing the entire computer forensic division," says Phil. "The division consisted of many people in various critical roles, including an exceptional team of site managers that I relied heavily on. Years later, I still stay in touch with most of those managers and many other people from the overall team. They have all grown professionally and it's amazing to see what roles they've taken on. It's humbling to see so many people really pursue the trajectory they set for themselves so many years ago."
In one of his most exciting cases, Phil provided forensic examination and overall investigative support to a law enforcement case involving hundreds of millions of dollars of fraudulent transactions committed against victims around the world. The case lasted several years and involved more than a hundred pieces of media from 10 countries, as well as numerous operating systems, filesystems, and criminal actors. With the ultimate arrest of two subjects high up in the organizational "food chain", the investigative team was successful in completely decapitating the fraudulent scheme itself, due to comprehensively scoping the architecture they used.
When he's not cyber-sleuthing and mentoring students, Phil is an avid runner who has completed two half-marathons and dozens of 5k and 10k races. He tries to run every other day even when he's teaching in order to keep his thoughts clear and his brain geared up. "I get 'rungry' (run hungry) when I skip a day," he says. Phil also enjoys craft beer because of the passion and creativity that today's craft brewers put into their product. Wherever he travels he searches out the local favorite to sample.

As a globe-trotting cyber sleuth, Ryan Johnson is always looking to find the bad guy, and to share his enthusiasm and knowledge about digital forensics along the way. Ryan started out performing digital forensic exams for local law enforcement in Durham, N.C., assisting in homicide, fraud, narcotics, and child exploitation cases. He quickly saw the importance of digital evidence in ensuring that guilty parties are held accountable and innocent parties go free.
That work led Ryan to join a team of media exploitation analysts working for the U.S. Army in Iraq. During his year in Iraq he helped gather actionable intelligence, streamline processes, and enhance equipment resources for in-country teams. When he returned stateside, Ryan began to work on computer intrusion cases. Since then he's traveled the globe teaching digital forensics for the U.S. State Department's Anti-Terrorism Assistance Program and served as a digital forensics analyst and consultant. Ryan co-authored several of the State Department's digital forensics courses as well as the book Mastering Windows Network Forensics and Investigations, Second Edition.
Today, with more than 12 years of experience in digital forensics investigations, incident response, network forensics, and vulnerability assessments, Ryan teaches the FOR572: Advanced Network Forensics and Analysis course for SANS.
"My favorite part of teaching for SANS- other than meeting some really cool students- is that I get to hear different perspectives and approaches to all the areas we talk about in class," says Ryan. "There's not been one class where I have not learned something from our students, and those nuggets of gold help me be a better practitioner and a better instructor."
Ryan also currently serves as the Global Head of CSIRT at PricewaterhouseCoopers, where he leads the response, readiness and investigations functions. In addition, based on his background, practical forensic experience, and government clearance, Ryan has been regularly called upon to train U.S.-based government departments, international governments, and corporations in the areas of network and digital forensics.
Ryan earned a Master's of Science degree from Dalhousie University and two Bachelor's degrees from Queen's University. He has taught college students, professionals, law enforcement, attorneys, and judges. Ryan knows that teaching the process, not the tool, is what gives students information they can put into practice outside of the classroom, and he works tirelessly to ensure every student understands the concepts he's teaching.
"I do my best to come up with unique ways to explain or relate information to people from different backgrounds and experience levels," he explains. "I've explained concepts using analogies like the 'paint can method' for understanding Diffie Hellman key exchanges, and a water pitcher and a glass to explain buffer overflows- inadvertently shorting out a computer at the same time! I don't like to stop until I see the light bulbs go on, so my classes aren't your typical 'download' sessions."
When he's not investigating, teaching, or traveling the world, Ryan uses part of his free time to delve into another of his passions, which is research.
"My research interests involve traffic analysis and potential subversion of IoT devices, specifically the ones I have in my house!" he says. At home, you might find Ryan playing with his kids, making dinner for the family, and brewing small batches of beer. And while he'd like more time for actual brewing, he always finds opportunities to make the process more tech-savvy, like building new controllers for his beer brewing setup!

Cindy Murphy served in law enforcement for more than thirty years. For twenty-five of those years, she worked at the Madison Police Department (MPD) in Wisconsin. While at MPD, she had the opportunity to serve as a detective and as a certified digital forensics examiner for over seventeen years. During her time as an investigator, she saw firsthand the emergence of mobile devices as the primary source of evidence in investigations. This pushed her to grow into the mobile forensics expert she is today and enabled her to co-author the SANS FOR585 Advanced Smartphone Forensics course. Just recently, Cindy took a leave of absence from the Madison Police Department to launch Gillware Digital Forensics, where she is co-owner and serves as president and lead examiner. As a life-long police officer, Cindy knows the transition from the public to the private sector to private will present new challenges, but she's looking forward to broadening her professional experience even further, which will benefit both Cindy and her students.
Throughout her career, Cindy has always looked for opportunities to help in meaningful ways. In one recent case, experts spent a year trying to unlock the phone of a 16-year-old girl who was killed in a tragic traffic accident. As the family prepared to spread the girl's ashes in a ceremony a year after her death, Cindy was given the victim's locked phone. She was able to unlock it, enabling the family to see their daughter's last photos. The family sent Cindy a thank you note that said: "We so appreciate this opportunity you've given us to hold onto a piece of our daughter's life we were sure was lost to us."
Digital devices have a huge impact in our world today, and Cindy believes mobile phones have become the diaries of people's lives. That's why mobile forensics is such a vital field. A thorough knowledge of these devices is thus crucial to investigations, since they can provide indispensable evidence that law enforcement can't afford to miss. Cindy knows the tools and programs that support digital forensics, has trained officers how to handle cell phone evidence, and knows how to take care of herself and others when working through tough cases like child pornography. Her extensive experience has given her both the real-world experience and the foundation in training that it takes to excel in the mobile forensics field and share her knowledge with others.
Cindy has been teaching digital forensics since 2002. In 2006, she helped develop the curriculum for a certificate program at Madison Area Technical College. Cindy has served as guest faculty for the National District Attorney's Association, testified as a computer forensics expert in state and federal court on numerous occasions, presented internationally on digital forensics topics, and written frequent articles and whitepapers. She as a master's degree in science degree in forensic computing and cyber crime investigation from University College in Dublin. Cindy is also a military veteran, a mother, an activist in defense of first amendment rights, a musician (banjo, cello, tenor guitar, mandolin, and ukulele), and a Brittany Spaniel enthusiast.

This favorite quote of Chad Tilbury has proven to be a recurrent theme throughout his career. When Chad attended the U.S. Air Force Academy, his interest was piqued early on by the thrill and challenge of engaging adversaries in new domains. Chad grew up enthralled by spy novels, so battling real spies with counter-espionage techniques was particularly appealing. A career in computer crime investigations was the perfect fit.
Chad has nearly 20 years of experience working with government agencies, defense contractors, and Fortune 500 companies. And his case list looks like it's been pulled straight from those spy novels he grew up reading: murder, abduction, espionage, fraud, hacking, intellectual property theft, child exploitation, terrorism, and computer intrusions.
He has served as a Special Agent with the Air Force Office of Special Investigations, where he investigated and conducted computer forensics for a variety of crimes and ushered counter-espionage techniques into the digital age. Chad has also led international forensic teams and was selected to provide computer forensic support to the United Nations Weapons Inspection Team.
In addition, Chad has worked as a computer security engineer and forensic lead for a major defense contractor and served as the vice president of worldwide Internet enforcement for the Motion Picture Association of America. In that role, he managed Internet anti-piracy operations for the seven major Hollywood studios in over 60 countries.
"With so many different skills and cultural perspectives on that team, I learned more about the dark underpinnings of the Internet than I ever could have imagined," says Chad.
Today, Chad brings his wealth of experience to his role as technical director at CrowdStrike, where he specializes in incident response, corporate espionage, and computer forensics. Here at SANS, Chad is a senior instructor and co-author for two six-day courses: FOR408: Windows Forensics, which focuses on the core skills required to become a certified forensic practitioner, and FOR508: Advanced Digital Forensics, Incident Response, and Threat Hunting, which teaches sophisticated computer intrusion analysis and advanced threat hunting techniques.
Chad's experience brings immeasurable depth to his classes. He focuses not only on tools and techniques, but also on understanding how those artifacts can be used to prove or disprove questions students are asked to investigate in their daily jobs. As Chad says, "Forensics is both an art and a science, and I find that hearing about real-world applications provides new perspectives and can help unlock a student's ability to think unconventionally."
Chad keeps his class goals simple: teach and lead discussions on the most important topics and make sure students have as much time as possible to work on the exercises. "I'm a big believer in hands-on learning," he says, "and we work hard to ensure the exercises in our classes are as realistic as possible. When students put all the pieces of a forensic investigation together themselves, it leads to those 'aha' moments that are so valuable."
The methodologies Chad teaches in his courses are the same ones he has used successfully on countless examinations. "Our exercises are months in the making, and provide realistic, real-world evidence samples on which to practice," says Chad. "I have had numerous students report going back to their teams, blowing them away with a new technique, and promptly becoming the trainer themselves."
One of Chad's most memorable experiences in the classroom brought that immediacy of techniques to a whole new level.
"I was teaching some of my latest research on browser artifacts, recently added to the FOR408 class. Research showed that a specific browser database could be missing a day or more of information if not properly handled. There happened to be a law enforcement officer in class who was investigating a murder, and in his examination of the suspect's computer he had noted missing data during a critical 24-hour period. From our class discussion, the officer now had a tool and technique to recover the missing data in his case. Not surprisingly, he left class early!"
In addition to being a graduate of the U.S. Air Force Academy, Chad holds B.S. and M.S. degrees in computer science, as well as GCFA, GCIH, GREM, and ENCE certifications.
In his free time, Chad loves to travel and takes full advantage of the unique destinations his career takes him. He spends much of his time at home mountain biking, skiing, snowboarding, and mountaineering. Chad recently took a ski mountaineering trip to Antarctica, about as far away from a Wi-Fi signal as you can get!

Jake Williams is a Principal Consultant at Rendition Infosec. He has more than a decade of experience in secure network design, penetration testing, incident response, forensics, and malware reverse engineering. Before founding Rendition Infosec, Jake worked with various cleared government agencies in information security roles.
Jake is the co-author of the SANS FOR610 course (Malware Reverse Engineering) and the FOR526 course (Memory Forensics). He is also a contributing author for the SEC760 course (Advanced Exploit Development). In addition to teaching these courses, Jake also teaches a number of other forensics and security courses. He is well versed in Cloud Forensics and previously developed a cloud forensics course for a US Government client.
Jake regularly responds to cyber intrusions performed by state-sponsored actors in financial, defense, aerospace, and healthcare sectors using cutting edge forensics and incident response techniques. He often develops custom tools to deal with specific incidents and malware reversing challenges.
Additionally, Jake performs exploit development and has privately disclosed a multitude of zero day exploits to vendors and clients. Why perform exploit development? It's because metasploit != true penetration testing. He found vulnerabilities in one of the state counterparts to healthcare.gov and recently exploited antivirus software to perform privilege escalation.
Jake has spoken at Blackhat, Shmoocon, CEIC, B-Sides, DC3, as well as numerous SANS Summits and government conferences. He is also a two-time victor at the annual DC3 Digital Forensics Challenge. Jake used this experience with, and love of, CTF events to design the critically acclaimed NetWars challenges for the SANS malware reversing and memory forensics courses. Jake also speaks at private engagements and has presented security topics to a number of Fortune 100 executives.
Jake developed Dropsmack, a pentesting tool (okay, malware) that performs command and control and data exfiltration over cloud file sharing services. Jake also developed an anti-forensics tool for memory forensics, Attention Deficit Disorder (ADD). This tool demonstrated weaknesses in memory forensics techniques.
Aptly called the "Yoda" of malware analysis by his students, Lenny Zeltser keeps his eye on the big picture and focuses on the sum of events rather than individual occurrences. He lives by that philosophy and brings it to his job and classroom. "Even those professional moments that seem insignificant by themselves can be an important piece of the progressive journey that, hopefully, takes us toward our career objectives and honors our ideals," says Lenny. "And you may not even see the value in those moments until you look back on the path."
A seasoned business and technology leader with extensive information security expertise, Lenny started his professional journey in a variety of technical infosec roles before serving as the national lead of the U.S. security consulting practice at a major cloud services provider. Later in his career he oversaw a portfolio of security services at a Fortune 500 technology company. Today, as VP of Products at Minerva Labs, Lenny designs and builds designs creative anti-malware products. Lenny is also a senior instructor at SANS and the primary author of FOR610: Reverse-Engineering Malware: Malware Analysis Tools and Techniques, a course he designed as an on-ramp into the malware analysis field. The course helps students expand and systematize their approaches to examining malicious software using a variety of techniques.
"My goal is to make this topic as accessible to people as possible," says Lenny. "There is indeed much one needs to know to understand the inner workings of malicious code, but the good news is that people can begin learning how to do this work by building on the technical skills they already have, whether they are grounded in system administration, network security, software development or other aspects of IT."
Like many of his students, Lenny's career path began in an IT role, which lends unique strengths to his information security expertise.
"My first job in IT was Unix system administration, then I moved onto Windows sysadmin, and then I spent a bit of time on software development," Lenny explains. "I found myself gravitating toward the information security aspects of these jobs. For me, Infosec exists at the intersection of many disciplines, and working in this field allows me to make use of the skills and interests I've acquired across various aspects of IT."
Along the way, Lenny earned the prestigious GIAC Security Expert professional designation, and he currently serves on the Board of Directors of SANS Technology Institute. Lenny holds a bachelor's degree in computer science from the University of Pennsylvania and a master's in business administration from MIT Sloan.
A co-author of four books on malware, network security, and digital forensics, Lenny also developed the Linux toolkit REMnux to make it easier to use a variety of freely available malware analysis tools, many of which run well on Linux but can be difficult to find and install. REMnux has grown to become a very popular toolkit and today is used by malware analysts throughout the world. The FOR610 course that Lenny teaches covers many of the tools installed on REMnux.
Lenny gives his students more than technical tools, however, and he says that the most important lesson he teaches his students is: "You can do it."
"It's easy to get discouraged when you run into professional challenges that you're not equipped to handle," Lenny explains. "But when you participate in SANS training, you encounter many new tools and concepts that you will be able to attach to the techniques you already know from prior experience in the field. Much of what you learn will occur after you finish the course and begin applying the concepts to your work outside the classroom. I strive to give students the confidence and the core skills they need to keep learning about and curtailing malware threats even after the class ends."
In his free time, Lenny indulges his love of food both as chef and consumer. "Eating a delicious meal in good company is always time well spent for me," he says. Lenny also loves to cook as a way to clear his mind, disconnect from the day-to-day challenges of business and IT, and connect with family and friends. Lenny subscribes to several food and cooking magazines and enjoys experimenting with new recipes, ingredients, and spices. "Not everything I cook turns into a great dish- sometimes experiments lead towards unfavorable results- so I keep reminding myself to think about this process as a journey, not as a destination."

This is what student are saying about Senior Instructor Lenny Zeltser:
- "Lenny presented a wealth of knowledge, tied it together smoothly, and I am leaving with exponentially more knowledge." - David Werden, NGIS
- "Last week, myself and three of my associates attended SANS GREM training. Based on previous recommendations by prior students, we explicitly attended this session given Lenny was the instructor. As someone who has been responsible for development and delivery of training and education services, Lenny is the best instructor I have ever encountered in my professional life. His approachable demeanor, passion for the learning process, and empathy for his students was just as impressive as his mastery of the curriculum. This praise was unanimous among my three associates." - Colin Sheppard, Vice President of Cyber Security & Fraud, International at First Data Corporation
- "Lenny is one of the reasons why it's fun to be in the information security community. His extraordinary intellect and talent for research and innovation is matched by his communication and teaching skills. He's a fantastic writer and a wonderful instructor who has mastered the ability to teach complex concepts in a very approachable manner. Lenny is also one of the nicest people you'll ever run into in our field or any other." - Eric Huber, Cyber Fraud Subject-Matter Expert
- "Lenny Zeltser is another one of those people you read about in magazines and think "Man, I wish I was that guy." A true leader in information security and a great guy all around. Lenny once actually paid me a compliment when I was teaching for SANS, along the lines of being inspired at the time by me being one the folks who happily stood up to teach in front of large crowds (we were both new to the game at the time). I found this humorous since I felt only awe at his own amount of knowledge. I still have the copy of Network Perimeter Security, which he personally sent me to get my opinion of it. I recall that I didn't end up providing my feedback since I felt beneath the ability to comment on it at the time!" - Ed Luck, Principal Consultant, Solutions at Dimension Data
- "I was part of the group that attended and reviewed Lenny's try-out session as a SANS instructor, and was blown away by the energy, expertise, and focus he displayed. Where others have at times failed to properly handle interruptions, especially from people who were trying to lead them astray and/or force them to stumble, Lenny remained focused, put the interrupter nicely but firmly in his place, and postponed further discussion to the Q&A session at the end of the class. When audience members asked targeted questions, inquiring about their understanding of recent developments in information security, he was able to elaborate on each of the topics and help them improve their grasp on various hot topics. Lenny displays lots of dedication, is very intelligent, has a solid grasp of information security, and is capable of explaining complicated technical concepts in easily understandable terms." - Roland Grefer, Principal, Global Support Services Group
When Eric Zimmerman was a Special Agent with the FBI, one of his responsibilities was managing on-scene triage. He identified several gaps in an existing process and started creating solutions to address them. What began as building and expanding a few live response tools took Eric down a path that eventually led to him writing more than 50 programs that are now used by nearly 8,800 law enforcement officers in over 80 countries.
Much of Eric's work involved designing and building software related to investigations of sexual abuse of children. In a single year, Eric's programs led to the rescue of hundreds of these children. As a result, in May 2012, Eric was given a National Center for Missing and Exploited Children's Award, which honors outstanding law enforcement professionals who have performed above and beyond the call of duty. Eric was also presented with the U.S. Attorney's Award for Excellence in Law Enforcement in 2013.
Today, Eric serves as a Senior Director at Kroll in the company's cybersecurity and investigations practice. At SANS, he teaches the FOR508: Advanced Digital Forensics, Incident Response and Threat Hunting course, and is a two-time winner of the SANS DFIR NetWars Tournament (2014, 2015). Eric is also the award-winning author of X-Ways Forensics Practitioner's Guide, and has created many world-class, open-source forensic tools.
Eric is a sought-after instructor and speaker who brings expertise in the cyber realm, complex law enforcement investigations, computer forensics, expert witness testimony, computer systems design, and application architecture to his work and classroom.
"I enjoy teaching this material because of how much potential there is in it to move cases forward quickly," says Eric. "With the pace at which computer storage continues to grow, it will become more and more important for people to understand the most cost-effective artifacts and techniques so these can be leveraged to move through data more quickly."
Eric's teaching philosophy focuses on the long-term gains achieved by not only understanding the nuts and bolts of how to run a tool and consume output, but also getting a deeper understanding of how tools work "under the hood." Those "a-ha" moments are what has kept Eric coming back to the classroom since 2008. His focus on understanding the big picture of digital forensics prepares students to perform better analysis, do new research of their own, and identify the best tools or techniques to perform successful investigations - all skills that will have a lifelong impact.
And even though work brings him great rewards, Eric understands the value of work/life balance. In his spare time, he enjoys spending time with his family, hiking, going to amusement parks with his two sons, and even fitting in a bit of video gaming when possible.
