DF Industry Happenings

The ArcPoint Team attended the National Law Enforcement Training on Child Exploitation in Atlanta, Georgia. We met with amazing end users’ and other key partners to demonstrate how to use ATRIOTM to improve their current workflows and streamline these processes. Our CEO, Amy Moles, was able to meet all the Electronic Storage Detection K9s trained by Jordan Detection. It was tough work but someone needed to provide all the pets to these heroes!

Coming up next month, Cyber Social Hub will be hosting a live webinar on July 13, 2022, at 2:00 PM with Cesar Quezada. This is a free event and requires individuals interested to register on the website. Cesar Quezada is an experienced technical professional with over 10 years of experience in digital forensics, military intelligence, and computer systems administration. He currently supports the DoD conducting forensic examinations and is currently a Company Commander of a Cyber Security Company in the Virginia Army National Guard. He has achieved a Master's Degree in Computer Forensics and numerous forensic and technical certifications. Cesar joined the military to give back to the community and help make this country a safer place. His path to DFIR wasn't conventional and he believes that applies to a lot of practitioners. But one common trait among practitioners that he believes is we all have the desire to help make this world a safer place.

He has experienced two overseas deployments to war zones. One in uniform as a military officer and one as a DoD contractor so he knows the difficulties of getting the right people trained and equipped. He believes in empowering more people by giving them the knowledge, tools, and technology to help in that cause so working with ArcPoint absolutely fits that bill. 

ArcPoint Company and Product News

The ArcPoint team has been busy adding features and testing new concepts and methods for performance enhancements. We're really excited about the performance results we're seeing and even more excited to share these with you in the future. These will be integrated into the version releases over the next few months. More on that later. In the month of May, we added some key features that we think people will find helpful.

  • ArcPoint added a "Not Safe For Work" AI model that will review photos for content such as nudity or that is explicit in nature. This category can be found on the AI-Object Detection reporting for photos as a new category.

  • ArcPoint’s R&D Engineers conducted testing on a few different data carving tools and ultimately made the switch to photorec. Testing reports concluded a 300% speed improvement in photorec over other tools we've tested and have seen consistency in the quality of the results as well.

  • DD images can now be processed similarly to an E01 image. If you have a .dd that was previously collected the E01 AS SOURCE feature is now E01/DD AS SOURCE. You can have multiple E01 or .dd images on a drive and ATRIO will triage all of them consecutively. 

  • ArcPoint has set the line limit for document translation to 50 lines. This change will ensure that the user can get a snapshot of what's in a file while avoiding an unreasonable amount of time for processing hundreds or thousands of documents that need to be translated. However, upcoming products will have an expanded capability with GPU support and even desktop CPU processing power to extend past the line limit for translation of documents.

Once a month ArcPoint releases a blog to help individuals within the community grow and expand their skillsets. Our content is intended to be used as a refresher for experienced examiners and help individuals just getting started to expand their skillsets to make investigations easier. Check out Acquire Evidence using LIBEWF on our website. Throughout this blog, we step through how to acquire evidence using the terminal on a Mac.

Monthly Tech Tip

Exiftool is a great open-source tool written by Phil Harvey that can extract metadata from numerous different file types. Most examiners know it can extract metadata, but not many know it can also organize files based on date. 

In this instance, we have a folder with a massive amount of images with random names, but we want to organize them into 2-digit Year and Month folders so that we can triage the newest images first. For that we will use this command with Exiftool:

$ exiftool '-Directory<CreateDate' -d /home/arc004/Pictures/Organized/%y/%y%m -r /home/arc004/Downloads/flickr30k_images/flickr30k_images

image 1

In this command, we are telling Exiftool to move all images from the “flicker30k_images” folder to a new folder called “Organized” and put the images in folders based on their creation date year and then year/month. This command also has the ‘-r’ to search recursively in the folder just in case there are subfolders in there.

Once completed we have a folder like this:

In summary, Exiftool can be used much more than to extract metadata from files. As we can see from this example, it can be used to sort files based on dates. Admittedly it is not a perfect solution, for example, if the file has no metadata, then Exiftool will not move it to a new folder, but it is still a better solution than having a folder with thousands of random files.
