- 0:00Hey everybody, thanks for tuning in for another episode of
- 0:03Parsing the Truth One Bite at a Time.
- 0:05This episode is a little different.
- 0:07We recorded this live at the Oxygen Forensics conference, so
- 0:13you will find in parts there is no video for a couple minutes
- 0:17and the sound might get a little muffled.
- 0:20We apologize for that, but we still think you're going to
- 0:23think it's a great episode. And finally, we have to thank
- 0:27Briggs for recording this for us and giving us our own personal
- 0:31laugh track. Thanks everybody and please
- 0:33enjoy. Join former FBI senior forensic
- 0:38examiners Becky Passmore and Stacey Eldridge as they dig into
- 0:42the world of digital forensics one bite at a time.
- 0:45Now leading their own consulting firms and educating the next
- 0:48generation of cyber sleuths, these badass babes of digital
- 0:51forensics bring sharp insight, real world case experience, and
- 0:55a dose of humor to the bits and bites that filled today's
- 0:57investigations. From deep dives into business
- 1:00e-mail compromise and ransomware attacks, Becky's specialty to
- 1:04cracking the complexities of iPhone forensics, Stacy's
- 1:06obsession, this podcast delivers insider knowledge for
- 1:09professionals, students, and true crime techies alike.
- 1:13If you've ever wondered what really happens when the digital
- 1:15trail is all that's left, TuneIn and start parsing the truth.
- 1:27Welcome to Parsing the Truth one terabyte at a time.
- 1:31I am Stacey Eldridge and as always, I have my Co host Becky
- 1:34Passmore with me for the live podcast at the Octogenic War in
- 1:39the conference Legacy and Logic. Today you're going to be looking
- 1:44back at 25 years of digital forensics, a journey from the
- 1:48days of loppy, dis and flip phones to the era where a single
- 1:53device can hold terabytes of secrets.
- 1:56Digital forensics has transformed how we uncover the
- 1:59truth. And today we celebrate the
- 2:01evolution, the innovation and the cases that change.
- 2:05Everything. Thanks, Stacy.
- 2:07Today we're exploring the evolution of digital forensics,
- 2:11the devices that defined an era, the artifacts have told the
- 2:16stories, and the complexity that continues to challenge us all.
- 2:20When we talk about the complexity explosion, we're
- 2:22going all the way back to the 1990's, the point where digital
- 2:27forensics truly began to accelerate into the massive,
- 2:30data-driven world we know today. The complexity explosion in
- 2:35digital forensics is a journey that some of us have experienced
- 2:38first hand, one where our world of evidence has grown not just
- 2:43in size, but in diversity, depth and difficulty.
- 2:48So let's take a look back at the different digital evidence eras
- 2:52it. Began in the 1990s, when our big
- 2:55cases revolved around. 1.44. Megabytes of floppy disk, which
- 3:00were considered cutting edge Sir Mix.
- 3:03A lot had baby got back and digital forensics folks had baby
- 3:08got bytes. Let's be honest, we like big
- 3:11data and we cannot lie. Evidence recovery meant
- 3:14repairing physical damage and navigating simple fat file
- 3:18systems. Forensic examiners were pioneers
- 3:21in interpreting bits, bytes, and strings of ones and zeros to
- 3:26tell a story that no one else could see.
- 3:31Forensic examiners were pioneers in interpreting bits, bytes,
- 3:35strings, ones, serums, all that tell a story that no one else
- 3:40could see. We didn't have advanced tools or
- 3:42automated automated parsing. We had to build the methods,
- 3:46understand the hex, and prove the digital traces mattered.
- 3:49It was never about managing millions of files, it was about
- 3:53finding that one deleted file that could change the direction
- 3:57of the case. It was about understanding how
- 3:59the metadata hidden within a document could lead to finding a
- 4:02killer. These are the moments in digital
- 4:04forensics that proved its worth in the pursuit of justice.
- 4:09Becky, the 2000s are rolling in, the data's getting bigger, the
- 4:14brides are heating up, and let's be honest, things are getting
- 4:17hot in the air. We changed when we started
- 4:21dealing with 40 gigabyte hard drives and a whole.
- 4:24New kind of forensic pressure. Yep, that's the early thousands
- 4:28again. Some of these weren't even born.
- 4:30During. The error of the hard drive.
- 4:33Suddenly digital evidence wasn't just a few files on a floppy
- 4:36disk, it was entire systems overflowing inboxes and the
- 4:41first wave of the mobile device data.
- 4:44We pulled plugs on scene and then imaged.
- 4:46Every bit of the hard drive. Because that was best practice,
- 4:49what used to take an hour now to a whole day, and sometimes even
- 4:54longer. Imaging became a waiting game,
- 4:56and patience was a new forensic skill.
- 4:59We were transitioning from carving deleted BIOS to
- 5:02reconstructing digital lives. The data told us who.
- 5:05What? When?
- 5:06And how long? Time stamps, logins, browser
- 5:10history all began point painting a clearer picture of human
- 5:14behavior behind the keyboard. But this era was also brought
- 5:17with new obstacles. Earlier forms of encryption,
- 5:21password protected files, and rapidly involving evolving
- 5:25e-mail platforms. Forensic tools were essential,
- 5:27but they were still young. Every update felt like a.
- 5:31Leap. Forward the hard drive error
- 5:33tested our endurance and our skill.
- 5:35It was no longer about if the evidence was there, it was how
- 5:38fast we could find it and if. We could breakthrough the
- 5:41barriers to reach it. Becky, what era did you begin
- 5:45in? Are we talking about our heiress
- 5:49tour in digital branches? I started in 2004.
- 5:54From Woppy diss to Probringe framework, I've been shaking it
- 5:58off ever since. Stacy, which era did you?
- 6:02Begin. Well, I started back in 2004 and
- 6:06was certified by the end of 2005 in the FBI and right when Justin
- 6:10Timberlake was bringing sexy back, I was bringing files back.
- 6:14By you. That is how we met through the
- 6:19training at the FBI. Like 20 tens.
- 6:22Digital forensics had stepped into an entirely new frontier,
- 6:25the era of social media, smartphones and the cloud.
- 6:30Storage capacity surged from a few gigabytes to terabytes,
- 6:34significantly increasing the complexity of our cases.
- 6:37Evidence now lived everywhere, in hidden Facebook messages,
- 6:42Gmail threads synced invisibly through the iCloud, fingered in
- 6:47apps, app data that users knew never knew existed.
- 6:51For the first time, the digital world was bigger than the
- 6:54physical one. And to learn how to investigate,
- 6:57and we had to learn how to investigate both.
- 6:59The challenge shifted from finding data, deciding where to
- 7:02start. Investigators now needed to
- 7:04navigate a growing network of platforms, accounts and cloud
- 7:09providers, all protected by privacy laws, Encryption, and
- 7:14ever changing access procedures. Search warrants expanded their
- 7:18scope from individual devices to encompass an entire digital
- 7:24ecosystem. Ryan warrants were challenging.
- 7:27Where did that data live physically?
- 7:29Did the warrant cover the location of the evidence?
- 7:32The house, the vehicle, the shed, the office, the cloud,
- 7:36then the server? But with that can complexity,
- 7:39every case meant thousands of files, dozens of devices, and
- 7:43countless log entries. The 20 Tens taught us that
- 7:46digital forensics wasn't about data.
- 7:49It was about meaning, about connecting fragments to form
- 7:53truth in a connected. World By the time we hit the
- 7:56late twenty 10s digital evidence was everywhere.
- 8:00Cloud, data, social media, mobile apps.
- 8:03It was coming at us faster than ever before.
- 8:06Honestly, Becky, I think by the end of the week most of us said
- 8:10I can't feel my face and I just want to move into the weekend.
- 8:13And here we are today, the 20 twenties, what we call the age
- 8:16of data overload. We've entered the TB era, where
- 8:19a single smartphone can hold more information than an entire
- 8:23evidence lab once did. Our digital device, our digital
- 8:27evidence, lives everywhere now, in the cloud, across Internet of
- 8:30Things, inside vehicles, smartwatches, doorbell cameras
- 8:35and encrypted apps. Let's not.
- 8:37Forget our refrigerators everywhere.
- 8:39Where encryption isn't an option anymore, it's the default.
- 8:42Every investigation is enormously complex.
- 8:45Massive data volumes, privacy hurdles, cross jurisdictional
- 8:49warrants, even AI generated content blurring the line
- 8:53between fact and fiction. This is where forensic steel
- 8:56meets innovation. Frantics is no longer about
- 8:59imaging a hard drive and waiting for results.
- 9:02It's about making real time decisions in the middle of an
- 9:04active investigation. Today, Digital Fundricks has
- 9:07shifted from recovering what was once lost to understanding
- 9:10what's happening right now. But here's the real shift.
- 9:14Instead of trying to know everything about everything,
- 9:17we've wanted to go deeper. We focus on understanding the
- 9:20artifacts more, mastering the tools better, and delivering the
- 9:24results faster. Our goal isn't just to process
- 9:28data, it's to interpret it with purpose.
- 9:31We focus on outcomes, on expectations, on clarity, not
- 9:34just the totality of the data. We've also recognized that no
- 9:37one can do this alone. The best examiners aren't
- 9:41isolated, they're connected. We collaborate, build networks
- 9:45of experts, share strategies that build bridge that gap
- 9:48between technical findings and legal storytelling.
- 9:51We're going to communicate better with attorneys to help
- 9:54them articulate what the data. Really means in.
- 9:58Court turning, technical complexity, city.
- 10:00Any 2 compelling truth. The 20 twenties have redefined
- 10:04our profession. We're no longer exist examiners.
- 10:07We're the technics of the scientists.
- 10:09We're analysts for report writers, educators, and truth
- 10:13finders operating in a world that never stops creating data.
- 10:18So as the data has evolved, so have we.
- 10:20From floppy disk to terabytes in the cloud, every leap in
- 10:23technology reshape how we investigate, analyze, and
- 10:27uncover the truth. But.
- 10:28Behind that evolution are the stories, the cases that tested
- 10:32us, changed us, and proved just how powerful digital evidence
- 10:37can be. Stacy, some of these.
- 10:44Cases didn't just make headlines, they had up stancing
- 10:47the night away in the lab, facing evidence through drives,
- 10:51phones and lobs until the truth came out.
- 10:54Let's talk about a few of those cases that truly changed the
- 10:58game. Absolutely.
- 10:59So in my opinion, one of the first big cases that helped us
- 11:03prove the power of digital forensics and how fast
- 11:06discovered by forensic examiners could be used to solve Major
- 11:10Crimes was the case of the BTK killer.
- 11:13The BTK killer had murdered people across Kansas for 17
- 11:17years and then nothing. He re emerged 14 years later
- 11:21taunting police. And during those exchanges, he
- 11:25posed a question. Can I send you a floppy gist?
- 11:28Can you track it? Be honest.
- 11:30So the detectives asked their forensic examiner, Randy Stone.
- 11:34Randy said there could be data on there that might be subtract
- 11:37him. So the detectives, oh BT killer
- 11:40No, go ahead and send us that floppy disk.
- 11:43Randy prepped for the floppy by conducting tests to ensure that
- 11:46X raying it wouldn't damage anything on it.
- 11:49They were fearful that explosives might be contained in
- 11:52it based on some of the. Things the BTK killer was.
- 11:55Saying and X raying it would prove no problem, wouldn't alter
- 11:59it in any way, and finally that purple floppy disk arrived.
- 12:03They rushed to the lab. The metadata of the RTF files
- 12:07present on that purple floppy disks contain clues and those
- 12:11clues would eventually lead to the killer.
- 12:14The metadata contain clues such as the name of a church Christ
- 12:18Lutheran, the name of a town Park City, a name to the last
- 12:23edited by field Dennis Rader It wasn't a confession.
- 12:26Dear police, I started killing people in 1974 and here are all
- 12:30my victims love Dennis Rader. No, nothing like that.
- 12:33It wasn't so obvious. It was the recovery of the
- 12:36metadata that would provide leads that that could be
- 12:39investigated and put together to discover who done it.
- 12:43And this metadata hold with solid investigation work finally
- 12:47led to a suspect confessing 3-4 years after the first murder.
- 12:53Dennis Rader finally admitted he was a BTK killer.
- 12:58How about the in the first infamous case involving digital
- 13:02forensics that went to trial? Let's talk about the Casey
- 13:05Anthony trial. This is one of the first trials
- 13:08that really exploded with social media, 24/7 news cycles and it
- 13:13was hot across the globe. And there was certainly lots of
- 13:16digital evidence in this case. 3 different digital forensic
- 13:20examiners testified multiple times and there was even a
- 13:23defense expert who stayed behind the scene, never entering the
- 13:27courtroom. But instead, instead, from the
- 13:29State House in Orlando, Larry Daniel helped the defense call
- 13:32into question the chloroform searches presented by the state.
- 13:36Now, for years, fingers have been pointing and saying they
- 13:40simply should have validated their results.
- 13:42And this case was used to teach people the consequences of not
- 13:46validating the results with two different tools.
- 13:49But what happens when two different tools don't agree?
- 13:53What happens when four different tools don't agree, such as what
- 13:57happened in this very case where Net Analysis and Case Cash Back
- 14:02and FTK all produced different results on that morgue database?
- 14:08They were all different. What then?
- 14:10So the strategy can be to try not to introduce those results
- 14:14into court because you couldn't validate them.
- 14:17But what happens if they do get introduced?
- 14:19Remember, we're there to answer the questions, not ask them.
- 14:24The prosecution wasn't supposed to ask John Bradley about the 84
- 14:28times that chloroform site was visited, but they did.
- 14:31Now, this opened up an entirely new line of questioning in the
- 14:35courtroom. And after thoroughly reviewing
- 14:37this case, Becky and I believe that the attorneys strategy,
- 14:41especially surrounding the chloroform site visit counts,
- 14:45did a disservice to John Crowder.
- 14:48This was further compounded by the fact that the Orange County
- 14:51Sheriff Office explicitly advised the attorneys to avoid
- 14:56that specific line of questioning.
- 14:58And in this completely unusual case, where lots of unusual
- 15:02things happen constantly, they had John Radley read in data
- 15:06from a report that he didn't generate.
- 15:08While he was on the. Stand now.
- 15:11The Orange County Sheriff's Office.
- 15:12Did state we're not going to use this data, We don't want to use
- 15:15this data, but that doesn't mean you're off the hook.
- 15:18The defense gets what you generated as a digital forensic
- 15:21examiner along with your reports, so they know what you
- 15:25know. So you better be prepared to
- 15:27answer those questions. So after all the time we spent
- 15:30on the Casey Anthony case, do you think there are new lessons
- 15:33learned for examiners? Yeah, I think you can find 2 new
- 15:36lessons learned out of this case.
- 15:38So from the Casey Anthony trial, we can learn first that lawyers
- 15:42are responsible for asking the questions and getting the
- 15:46evidence in. I think it's super easy to
- 15:48forget their role in all of this because we can prep with them
- 15:52and have discussions with them about everything we think about
- 15:55the digital evidence and what we think is important and what we
- 15:58want to say when we're on the stand.
- 16:00But ultimately the attorneys are there to present evidence and
- 16:04arguments to support their clients position.
- 16:07Secondly, avoiding unreliable data simply isn't the answer.
- 16:12You should be prepared to answer questions about it because even
- 16:16if your lawyer isn't going to ask you questions, I think about
- 16:19it the other. Side just might.
- 16:21That's right. But what about a case that isn't
- 16:23so old? You know, good to say.
- 16:24Taylor way that thin. Yeah.
- 16:26Casey Anthony way back. There are cases involving
- 16:29digital forensics still making the news today.
- 16:33Anybody heard of a little trial involving Karen Reed?
- 16:36The 1st. Child or the second child?
- 16:39Well, I mean, both, both of these trials were feisty because
- 16:44the defense or the prosecution, their digital forensic experts
- 16:48had completely differing opinions about a little artifact
- 16:52from the browser state DB and also what a little red FS mean.
- 16:56These opinions were so different that one expert's conclusion
- 17:01enabled the defense to not only say Karen Reed did not do it, it
- 17:06enabled them to use this artifact to imply that others
- 17:10were responsible for the death of John O'Keefe during the first
- 17:13trial and throughout the trial. Lots of digital evidence
- 17:17centering around the iPhone. But of course we had vehicle
- 17:20forensics. There was video footage and even
- 17:22time stamps all being called into question.
- 17:25But who knew a little red X in a tool had lead to such differing
- 17:30opinions? So what's the difference between
- 17:33a record being marked as recovered versus a record being
- 17:36marked as deleted in your? Tool.
- 17:38Do you know? Second, how do you validate if
- 17:41someone is deleting that record on purpose or if instead this is
- 17:46simply how the iOS and the database are interacting
- 17:50together? Let's jump into some lessons
- 17:52learned now. First, I think the first lesson
- 17:54learned from Karen Reed's trial is let us see how a little Red X
- 17:59should remind us the importance of knowing how your tools work.
- 18:04So not only does this show the pitfalls of over reliance on
- 18:08automated tools, perhaps it demonstrates the importance of
- 18:13intending vendor training so you know how your pools actually
- 18:16work. Now we can jump into House Long
- 18:21to die in the cold. It was a Google search found on
- 18:25Jennifer McCabe's phone. This Google search for House
- 18:28Long to die in the cold is what turned the Karen Reed case into
- 18:32a true crime phenomenon. The defense claimed that this
- 18:35claim was made hours before Don O'Keefe was found dying in the
- 18:39snow, and this suggested that someone knew he was there and
- 18:43didn't save him. Now it was Richard Grieve's
- 18:46affidavit, the defense expert, who said that this search
- 18:50occurred at 2:27 AM and this kicked off a whole chain of
- 18:55events where it would resulted in additional forensic examiners
- 19:00being called in, calls to celebrate hours and hours of
- 19:03additional testing and validation, and even Jennifer
- 19:07McCabe being harassed for months and months by the public.
- 19:11This search for House Long to die in the cold was found in the
- 19:14browser state DB. It was not found in the history
- 19:18DB. These are two different
- 19:20databases. That serve.
- 19:21Two different purposes. The browser state DB, the ogler
- 19:25simplify, is basically tracking your tabs and their status.
- 19:29It is not tracking all of your browser history.
- 19:32However, the history DD tracks your Internet browsing in Safari
- 19:37on your iPhone. This brings us to the second
- 19:39lesson learned that browser state DD artifact for the search
- 19:43for house, long to die and hold demonstrates that no artifact
- 19:48lives in isolation. You need to validate your
- 19:51conclusion by looking at related artifacts, and in this case, it
- 19:54was important to take a look at that Internet history as well.
- 19:58In addition to doing that, I think it would have been crucial
- 20:00to review the events that were occurring immediately before and
- 20:05after that search allegedly took place at 2:27 AM.
- 20:10You have to build the whole. Picture So since there was so
- 20:14much disagreement over that House Long to die in the cold
- 20:18artifact, was it included in the second trial?
- 20:21It is worth noting that that digital forensic examiner for
- 20:23the defense that was used in the first trial did not come back to
- 20:27the second trial, nor did they use that house lawn to die in a
- 20:31cold defense strategy. So, any more lessons?
- 20:34Learned in the Karen Reed trial. You bet there are.
- 20:37Let's pick up with the third lesson.
- 20:40The Karen Reed trial shows us just how complex iPhone exams
- 20:44are and the importance of testing and validating what
- 20:47you're seeing when you're stating that something happened.
- 20:50The two witnesses for the state, Jessica Hyde and Ian Whitman,
- 20:54both conducted tests on iPhones to be able to confirm the
- 20:58significance and the meaning of the data that they were talking
- 21:01about. During the first trial in the
- 21:03courtroom, they spent time discussing what they're testing
- 21:06was, what they did, and what it meant in terms for that house
- 21:10long to die in the cold surge and what it meant for the
- 21:14browser state DB versus the history DB.
- 21:17Now during the the second trial, Ian Witham went on to spend more
- 21:21time talking about additional testing he had conducted and
- 21:24that was related to the Apple Health data.
- 21:27But I'm going to come back to Apple Health data in a minute.
- 21:30Let's focus on why we should test and validate.
- 21:33Remember, the tools are just that, tools.
- 21:36They help us get the job done. It's our responsibility to check
- 21:40that they are interpreting the data correctly.
- 21:42I also find it so odd that in an industry full of people who are
- 21:46typically so suspicious of everyone and everything, but
- 21:51when it comes to our vendor tools, we tend to put a lot of
- 21:53blind trust in them. I'm not saying the tools are
- 21:55garbage. Absolutely not.
- 21:57We have to use them to get through the mass amounts of data
- 22:00we are facing today. We're no longer examining every
- 22:03bit on every device that we get. But when it comes to altering
- 22:07someone's life forever and the ripples that come with it, we
- 22:10have to take a moment and test and validate the assertions that
- 22:14we are making. And there is so much data on the
- 22:17iPhones and when you're relying on that data that goes beyond
- 22:21simple artifacts such as pictures and text and you're
- 22:24starting to dig deep into the data denses.
- 22:26And now we're even starting to get into the unified logs, all
- 22:29of that data and the new information they can provide.
- 22:32We can't blindly rely on the column names to accurately
- 22:37document the data contained within them.
- 22:39For the remaining if you've ever looked at column name in a
- 22:42database, in an Apple database, you will see that the names are
- 22:46just crazy. Why do so many of them start
- 22:48with ZDDDI? Have no idea, and it makes no
- 22:53sense. But one of the things that
- 22:55shockingly happens with Apple is native release.
- 22:58New IS versions all the time. And those new versions and green
- 23:03changes, and sometimes those Apple engineers just shove the
- 23:07new data into old columns. Now testing is going to bring
- 23:11truth to the many assumptions we've held for years.
- 23:14So now I want to loop back to that Apple Health data.
- 23:17Have you ever heard people saying for years that when it
- 23:19comes to Apple health floors, they can be other either up or
- 23:24down? Well, they can't.
- 23:26They're just up. Now we have to remember that
- 23:29this data is related to health tracking, health apps and
- 23:32fitness apps and trackers. They don't care that you're
- 23:35going downstairs. They care that you're going
- 23:37upstairs for health purposes. That's what you're going to
- 23:40track. And I'm not saying that it's up
- 23:42because this is based on my assumption that they care about
- 23:44up for exercise and fitness. I'm basing this on the fact that
- 23:47there is actually an additional database related to Apple Health
- 23:51data and it's seldom talked about or this database shows.
- 23:55The sets. So please stop saying that the
- 23:58floors climb can be either up or down.
- 24:00It's simply up. I'm going to talk about some of
- 24:03the databases and the names may slightly vary depending on your
- 24:06iOS. I'm talking about a case I work
- 24:08so if you would look at the cash encrypted c.tv you will see
- 24:13floors ascended and descended. But then if you go back to the
- 24:19dot S2 like, you'll notice that it's not like doing math with
- 24:23it. It's not adding the floors up
- 24:25and then subtracting the floors down and then giving you a sum
- 24:28total. It's not doing that.
- 24:29All it's doing is reporting all of the floors ascended together.
- 24:33So it's just up now. How did I know?
- 24:37Because I tested it and I asked other examiners what they saw.
- 24:41Now, why did I test it? Because in a case I had, it made
- 24:44a huge difference if the floors were going up or down.
- 24:48But testing and validating could be really tricky, especially
- 24:52with when you're getting an old case.
- 24:54Getting that to the right iOS and on the right phone can be
- 24:59downright impossible. And getting the right devices
- 25:02can also be expensive and it can be time consuming.
- 25:05And therefore, four, it can be extensive for your client to pay
- 25:08for as well. Now let's move on to a fourth
- 25:11lesson. During the trial, we also got to
- 25:13watch an expert get raked over the coals for listing a degree
- 25:17they hadn't earned yet on their CD.
- 25:19And I think this is a subtle reminder.
- 25:21Lawyers will attach you with whatever they can, whenever they
- 25:25can to make you look bad on the stand.
- 25:29Now finally, it's really easy for us to sit up here and tell
- 25:33you what we think after we've had the ability to go back and
- 25:36watch both of the care and read trials twice and then replay
- 25:40certain parts of it over and over again and then having the
- 25:42luxury of conferring with our notes.
- 25:44But how would have this done all done down if you or I have been
- 25:49on the stand, if we have been an expert And what questions would
- 25:53the lawyers have asked us when we were in the hot seat?
- 25:55Who knows? But we have the ability to go
- 25:58back and watch these trials, any of these trials, and this is a
- 26:02huge learning experience for all of us, and it's free.
- 26:06Becky, let's. Crank up the nostalgia back when
- 26:09Nirvana ruled the airwaves and the forensics smelled less like
- 26:12Teen Spirit and more like First Circuits.
- 26:15Let's walk through some of the devices that started it all.
- 26:19Yeah, let's do that floppy disk. The tooth over there?
- 26:23Yep, so do. You want to see?
- 26:28These you have a. Few floppy disks here, so with
- 26:33the 8 inch, the 5.25 inch, the 3 1/2 inch.
- 26:37The floppy disk family marked the beginning of portable data
- 26:41storage. The 8 inch was introduced in
- 26:431971 held a near 80 kilobytes of data, mostly used 5.
- 26:50The smallest 5.25 inch version was 1976 to the 1990s that
- 26:57increased the capacity to a whole 1.2 megabytes.
- 27:01The company. Use this for playing organs.
- 27:03Now I. Hope, England.
- 27:06Out of the century. Becoming the standard for early
- 27:09PCs by the mid 1980's, the 3 1/2 inch floppy arrived sturdier,
- 27:15protected by a hard classic shell and capable of storing up
- 27:18to 1.44 megabytes. But which one is the real floppy
- 27:24disk here? Which one?
- 27:26Which one? Red or yellow?
- 27:27The one's real. Red depends how you define
- 27:29floppy. The red one is an actual floppy
- 27:31dish, this one's just so the 3 1/2 has.
- 27:34No longer floppy. Good gist software installation,
- 27:38document transfers, or what we call sneakernet and saving
- 27:43critical system data long before flash drives or the cloud even
- 27:47existed. The popping still lives on your
- 27:51computers today as the save icon.
- 27:53A digital fossil from computing's early days now.
- 27:58Hard drives were certainly around way back when, but they
- 28:00were small. They weren't small in size in
- 28:03terms of this one, but they were small inside of around 80
- 28:08megabytes, yes, megabytes. Now in the 90s, Windows 95 had
- 28:14users demanding more storage and then so we had one and 2
- 28:18gigabyte hard drives that were. Becoming more.
- 28:21Commonplace and by the end of the 90s, ten gigabytes was
- 28:24pretty standard. But then in the 2000s, we were
- 28:27there for the 40 gigabyte hard drive.
- 28:29And I remember in the lab constantly energy 40 gigabyte
- 28:33hard drive after 40 gigahertz, 40 gigabyte hard drive.
- 28:36And then came the bigger ones. We were starting to get the 80
- 28:39gigabytes and then we jumped to 1:20 and then we jumped to 2:50.
- 28:43And then 500 gigabytes was pretty standard for quite a
- 28:46while. But today it's pretty common to
- 28:48see one terabyte solid-state drive and even the cheapest of
- 28:53laptops and external hard drives at anybody's house could average
- 28:5710 terabytes. But did you know that Toshiba
- 29:00plans to release a 40? Terabyte hard drive.
- 29:03In. 2027. Bigger data it's coming and over
- 29:07time, I mean this hard drive I hear I think it was 40 gigabytes
- 29:11and the laptop it was it had all the pins for the IDE drives as
- 29:16well. But this one and this was I
- 29:19think I got this one in 2006, this little thumb drive was 4
- 29:23gigabytes and we were like that's amazing.
- 29:25It's 4 gigabytes and it's and it's so small and this thumb
- 29:31drive I here have here now is 120 gigabytes on this little
- 29:34one. I think this teeny tiny one here
- 29:37is also 120 gigabytes. So we've really compacted down
- 29:42on how much data we can fit on something so small.
- 29:46And then as sizes increase but the devices decrease, sometimes
- 29:50it became harder find some of these things when we are going
- 29:53out on our first warrants to find stuff.
- 29:56But let's jump. Back into the.
- 29:57History of the hard drives and solid-state drives themselves.
- 30:01I think it's interesting to go for some of the physical
- 30:03connections as they've evolved over time.
- 30:05They actually first started out with SCSI interfaces.
- 30:09I wasn't dealing with a lot of SCSI in the FBI in terms of hard
- 30:13drives, but I was using SCSI to send all of my images to tape.
- 30:18And we had, as we mentioned, the IDE drives.
- 30:20And we had to struggle with making sure that the jumper cap
- 30:24was on the correct pin. And we had to make sure we have
- 30:27the right configuration where we putting it into master slave or
- 30:32cable select. And we had to make sure we got
- 30:34it right before we did. Let me tell you, don't even ask
- 30:38chat GOTP to like diagram out something like this for you,
- 30:41especially on the bigger hard drives and label what was what
- 30:44because it Simply put it even after being given the picture of
- 30:48what it shows like. So now the SATA drives hang
- 30:52along in the 2000s and they gave us a lot more speed.
- 30:55So we're excited about that. But of course, we can't forget
- 30:59about the solid-state drives that came around around 2010 and
- 31:03we were spending a pretty penny so we could get a 64 gig
- 31:06solid-state drive into our exam machine.
- 31:08So it could be the 10th drive. Now, Becky, what about some
- 31:12other drives that weren't computers but still had Disney
- 31:15Elevens? On them we have the iPod 1st
- 31:18generation released in October 2001 and it would redefine that
- 31:23portable music with its promise of 1000 songs in your pocket.
- 31:28It transformed the way people interacted with music.
- 31:31Sleep Simple and shockingly powerful.
- 31:34At its time, there was 5 gigs of the hard drive that could store
- 31:391000 songs. It had 10 hours of playback and
- 31:43the original iPod sparked a total shift because music became
- 31:47personal, portable, and perfectly, perfectly organized.
- 31:50It paved the way for that iTunes store and eventually the iPhone.
- 31:55The very first iPod could only be used on Maps.
- 32:01But Microsoft, as always, comes out a few years later with the
- 32:05competitor. So here we have the Microsoft
- 32:09Zoom introduced in 2006. My Zoom still works, still has
- 32:13my music on it. I will say I like it better than
- 32:16the iPod. Why?
- 32:18Because my headset, the port was in the top and not in the
- 32:22bottom, so I could like set it down while I was exercising and
- 32:25stuff like that. But anyway, so the Zoom,
- 32:28Microsoft's answer to the iPod, it offered wireless sharing
- 32:32before AirDrop existed. You had customizable backgrounds
- 32:36and you could have a Zoom Pass that would give you unlimited
- 32:39music. But despite the innovative
- 32:42ideas, it never gained traction because that five years later,
- 32:46I've already had mass dominance with the iPod.
- 32:50Now, it did have some social sharing where you could do
- 32:54wireless song swaps and then you could share a song with your
- 32:57friend and then they could play it three times in three days.
- 33:01Then you had. Your original iPad 20,000, I
- 33:04mean 2010, Apple's first iPad introduced the post PC error.
- 33:09It was sleek, touch driven and blurred the lines between a
- 33:13laptop and phone. Steve Jobs introduced it from
- 33:16couch saying it was better than a laptop, better than a
- 33:19smartphone. We also have the iPad 2 that was
- 33:23noticeably thinner, offering better performance and
- 33:28usability. Next up came the iPod Mini.
- 33:32So the IT was still just black and white, but it was much
- 33:35smaller. It was tiny and cool and it
- 33:38finally made digital music feel personal.
- 33:41And it's new click will became iconic.
- 33:44Now this was discontinued after just 18 months.
- 33:48It was replaced by the iPod Nano and that is the beginning of
- 33:53Fashion meets. So the iPod Nano 2005 to 2017
- 33:59now evolved across 7 generations from candy bar design to
- 34:04touchscreen music companion. It symbolized portability and
- 34:09professional and personalization and a little known fact.
- 34:12About this is the 6th. Generation of Banano was so
- 34:16small people wore it as a watch with third party wrist straps so
- 34:22I wonder if that's how they came up with this iWatch.
- 34:25Next up we have the Nokia phone early 2000.
- 34:29This is a classic. Nokia dominated the pre
- 34:32smartphone era with models like the 3310.
- 34:36It was known for its indestructibility, long battery
- 34:39life and snake. Now it did work on the 2G GSM
- 34:44network. It had a monochrome display.
- 34:46So that means you know monochrome either black and
- 34:48white or black and green depending on your version.
- 34:51But anyway, battery in. The state could last for. 10
- 34:55days, could you imagine not having to charge your phone
- 34:58every single night? And you also had physical
- 35:02buttons and you could just touch these buttons.
- 35:06But if you wanted to text, you had to go through the numbers.
- 35:09So if you wanted to see, you had to hit one free time.
- 35:12But some people could text like monsters on this.
- 35:15They were machine. It was amazing.
- 35:17Also, the Nokia 3310 could survive drops and possibly a
- 35:22mild apocalypse. Then you get this Motorola Razor
- 35:27which was launched. In 2004.
- 35:28It wasn't just a phone, it was a status symbol.
- 35:31The razor brought style to the mobile.
- 35:33World. For the first time, a phone was
- 35:37more about fashion and and less about function.
- 35:41But it has a. Camera, it had five megabytes,
- 35:46megabytes internal. It had Bluetooth, a mini USB and
- 35:51you could talk on it for seven hours.
- 35:53And it came in different colors. It was the fashion.
- 35:56Motorola sold over. 130 million units, making it the best
- 36:03selling phones ever. The Razor paved the way for the
- 36:06modern smartphone design, and it showed that people didn't just
- 36:09want technology, they wanted technology.
- 36:13We also. Have an original iPhone.
- 36:15The first generation. Was out in 2007 not too bad but
- 36:21when Steve Jobs announced the iPhone he said it's an iPod, a
- 36:24phone and an Internet communicator.
- 36:27It's all in one Honey changed tech forever.
- 36:30Early iPhones introducts introduced the multi touch
- 36:33interface and it was the beginning of the apple and the
- 36:37app ecosystem. Fun fact the original iPhone
- 36:41didn't have copy and paste. It didn't have video recording
- 36:44or picture messaging. So these devices.
- 36:47Weren't just part of our digital lives, they were the first
- 36:50digital evidence items that taught us how to recover,
- 36:53extract and preserve data. Each one challenged us to learn
- 36:58new tools, adapt new techniques, and build the foundations of
- 37:02modern digital forensics. So what began as curiosity about
- 37:06how it works became the science of how to find the truth inside
- 37:11the data. These early devices paved the
- 37:14way for today's advanced methods of acquisition, analysis, and
- 37:18preservation, reminding us that every byte has a story and every
- 37:23artifact has a legacy. From floppy disks to forensics
- 37:27in the cloud, our field has transformed from recovering
- 37:30single deleted files to to analyzing entire digital
- 37:34ecosystems E Jira has brought new devices, new challenges, and
- 37:39new lessons. But one thing has never changed.
- 37:42Our mission to uncover the truth one terabyte at a time.
- 37:45Today, 1 byte at a time when we started.
- 37:48The stories we shared today remind us that Digital Cranks
- 37:52isn't just about data. It's about people, decisions,
- 37:56and accountability. Every artifact tells also
- 37:58storing, and every examiner has a responsibility to make sure
- 38:01that story is accurate, tested and validated.
- 38:05We've. Seen how metadata can touch a
- 38:07killer, how validation can make or break a trial, and how
- 38:11testing reveals the truth behind the tools we trust.
- 38:14The devices have evolved, the data has exploded, and the
- 38:18states have never been higher. But through.
- 38:20It all our purpose. Has remained clear to interpret
- 38:23the data with integrity, communicate it with clarity and
- 38:27it's always seek the truth. Because in the end, it's not
- 38:30just about technology, it's about trust.
- 38:34The evidence may look in the digital world that the impact,
- 38:37but the impact lives in the real 1.
- 38:42And that's why we do what we do. This has been parsing the truth
- 38:46one bite at a time. Thanks for joining us live at
- 38:48Oxygen Forensics Conference where legacy and meets logic.
- 38:52The future of digital forensics continues to unfold.
- 38:55And we've survived the 1st 25 years and we will survive the
- 38:59next 25 years. Until next time, stay safe, stay
- 39:03sharp, and as always, keep parsing the truth one bite at a
- 39:06time. It's if you enjoyed this
