A Conversation about Transitioning to Incident Response

In working on AboutDFIR the last couple months, I’ve come to learn that while digital forensics and incident response share some basic foundational knowledge, they are widely different in practice. I’ve taken SANS FOR500: Windows Forensic Analysis and have been reading the recent articles about vulnerabilities, and have to say it’s been a series of eye-openers, especially coming from a law enforcement digital forensic background, as to how evidence and analysis can differ depending on…

DFIR Without Certs – What Books Can Help You

This has been an absolute long time coming from me, I think! The reason for this is during the crazy times we currently live in here in 2020, this is probably something I should have worked on much earlier to give folks a bit of a leg up on some reading material. Coming full circle, I feel this is something that really needs to be updated within our field. One of the few places where…

A General Overview of DFIR Resources

Introduction The world of Digital Forensics and Incident Response (DFIR) is so expansive that it's impossible for one person to know it all, let alone a fraction of it. To combat this, one must first be aware of and second utilize the resource that's best catered to the issue at hand. There are multiple resources out there that digital forensic examiners and incident responders should be aware of. Not all resources are created equal nor…

Jailbreaking – Checkra1n Configuration

In this installment, I felt that I should discuss how to use Checkra1n, and how to actually get into the device via 2 methods: localhost (tethered) and WiFi (untethered). This is not a blog to discuss how Checkra1n is doing, what it is doing, or what Checkm8 is doing prior to the device booting. Additionally, you do this at your own risk. Just because it works on one device does not mean it'll work on…

Magnet User Summit 2019 Impressions

I wanted to make a quick note to start the blogging back up again (yes, I know -- don't judge me!) by discussing a recent Digital Forensics Summit that took place during the first week of April here in the United States. While there is some bias to this since both Devon and myself did present at the Summit, there is in no way, shape or form any endorsement or payment from Magnet for what…

Forensic Tools

Forensic tools, whether software or hardware, or just like traditional forensic science tools - they are designed by humans and typically meant to be used by trained users who understand both the artifacts they are processing as well as the results produced by the tool. Some tools are as simple as a USB write blocker - you plug one end into a computer, you plug a USB device into the other end, and it "just…

Rick Kiper’s Research Project

A personal friend and FBI colleague of mine, Rick Kiper, has a research project that he is currently working on for Forensics. The next phase of his research study is to develop a digital forensics tool typology. Basically, the goal is to identify the most important characteristics of digital forensics tools, so that a forensic examiner may be able to quickly assess and select a digital forensics tool appropriate for a particular task. The goal…

Yandex.ru and Intrusion Investigations

Quite often I notice that unauthorized actors who compromise RDP access will execute a native web browsing application and navigate to a website such as whoer.net to enumerate browser header information, IP address, ISP, and a smattering of other host identification information. In reviewing these cases with forensic tools, I would also quite often see a hit for https://mc.yandex.ru/metrika/watch.js. Observing a .ru domain hit usually raises my suspicion level a bit, but I could not…
