FORENSIC ANALYSIS
- Kasasagi at ‘Apprentice forensic ‘s note’ has identified the ‘bam’ key in the Windows registry that stores the full path of an executable and the last execution time. It is indicated that this is only written when the computer is shut down so checking the registry on a live system may not be accurate (without parsing memory).
About bam key (execution trace?) (Last update: 2018/02/23 02:23) - Hideaki Ihara at the Port 139 blog looks at verifying some of the data found in the ‘bam’ key.

- The first introduces a project to look into “Pick Up Where I Left Off”, which is a feature coming to Win10 in the near future. This feature is meant to be a “cross-platform version of Apple’s Handoff and Auto Resume features”
Windows Fall Creator Introduction - The second project relates to examining a large number of popular apps across Android, iOS, and Windows Phones. I’m never sure if it’s good to include Windows Phone in these projects; on one hand, they’re very rarely seen, and on the other, they’re a pain because there’s little research on them because they’re so rarely seen.
Mobile Device Forensics Update 1
- The first introduces a project to look into “Pick Up Where I Left Off”, which is a feature coming to Win10 in the near future. This feature is meant to be a “cross-platform version of Apple’s Handoff and Auto Resume features”

- Matt Suiche at Comae Technologies explains a method of periodically obtaining memory images from critical systems within an organisation and analysing them with their Stardust tool.
Rethinking Logging for Critical Assets - Gayle Kennedy at Countercept explains how they have had more success with behaviour-based detection than signature-based detection for threat hunting.
How Do We Detect Signature-Less Attacks? - Joe Slowik at Dragos expressed similar sentiments (in many many more words): “developing an understanding of network security events through a behavioral perspective rather than a single observation point (atomic IOC view) ensures analysts are better positioned to understand and respond to malicious events as they are identified.”
Threat Analytics and Activity Groups - Russ McRee at HolisticInfoSec shared a post last week that I missed, HELK vs APTSimulator, in which he runs APTSimulator and then does a “fast run-through with HELK’s Kibana Discover option looking for the above mentioned APTSimulator activities”

A Slice of 2017 Sofacy Activity - Henrik Johansen shares details of HashiCorp’s Nomad, which is “a very fast and secure cluster scheduling system [and has been looking into it to see] how such a system might be applicable to the field of Information Security.” This can be used to schedule memory dumps or running YARA rules for example, in your threat hunting operations.
Cluster scheduling systems for large scale Security Operations

Forensic Lunch: 2/23/18 - Dave and Matthew ran a Forensic Breakfast instead this week, to allow us Australians to watch at a more reasonable time. Dave asked me to come on to talk about my work on this blog, including the podcast and patreon, and also my movements at a few conferences in May and June. Afterwards, Brad Schatz spoke about his recent updates to Evimetry; in particular, the new deadboot agent. Something I forgot to mention re how do I find things. the TLDR is I check a number of sources weekly, and try to find what people share out across various platforms. If you have RSS, great, if you don’t it goes on a list which I check before the post goes out. What’s been happening more recently is people are telling me prior to their release or letting me know if I missed something (which is great, because I do miss things). Really the only things I don’t share are marketing things or stuff that’s been reshared multiple times. I’d much prefer someone asks why I missed something since chances are it was just overlooked (or IFTTT didn’t run properly, which has happened recently). Overall, the best thing from my perspective is if you’re starting something new or sharing out something you want the DFIR community to know about, let me know and I’ll get it out there. After all, if I can’t find it, there’s a good chance many others can’t either.

MISCELLANEOUS
- Eric Huber at ‘A Fistful of Dongles’ has started a series on DFIR life after working in LE. This post covers the decision to leave LE to join the private sector and things people should consider. My main take away is: “you should always be preparing for the next job even if you aren’t actively looking for the next job”; I’m quite happy where I am at the moment, but one of the reasons I started this blog was because it would force me to keep up with what’s going on around the industry (not just necessarily the stuff I deal with at work) so I was better preferred if I decided to move on. (If my employers are reading this, I’m not looking to move on, don’t worry :P)
Life After Law Enforcement: Do I Stay Or Do I Go? - Brett Shavers wrote a couple of posts this week
Making Ham Sandwiches in DFIR - The first expounds the benefits of writing clearly, for your intended audience. If you write your report, and your audience doesn’t understand it, then it doesn’t really count.

Using technology to get results - Adam at Hexacorn has written a lengthy piece of advice for new SOC analysts to take onboard when starting (although a lot of this advice can be applied across the board).
How to become the best SOC Analyst E-V-E-R - Paul Kincaid at Malwarebytes Labs has started a series on building an effective incident response program in response to GDRP. This post outlines “some of the regulatory requirements documented in the GDPR”
How to build an incident response program: GDPR guidelines - Vitaliy Mokosiy at Atola Technology provides a list of forensics conferences for 2018 and 2019 (including approximate prices where possible). Forensic Focus also shared a code for a discount for Techno Security (which I’ll be attending this year!)
Top forensic conferences 2018-2019 - Blackbag Technologies have changed the devices that they will be distributing Macquisition on. Macquisition will now come on a 120GB solid state drive, and is upgradable to 1TB. I wouldn’t rely on imaging to the 120GB drive, only because most Mac laptop models are minimum 256GB (only the air comes with 128GB), and I wouldn’t want to rely on the compression; but for data collection and memory capture it’ll be great!
Macquisition’s New Device Sizes Provide Supersized Imaging
