#DFIR Automation Series

I use 4 levels of automation ranging from none to fully automated.

I think an ideal solution is to use full automation for low risk decisions. And recommendations for higher risk.

We use recommendations in Cyber Triage by scoring each artifact. You ultimately decide.

DFIR Next Steps: Suspicious TeamViewer Use Welcome to the next post in our DFIR Next Steps series on Remote Monitoring & Management (RMM) tools. This series is designed to help you quickly

New Forensic Resource

What to do after you find TeamViewer:
→ Log files to find activity details
→ Executables to find installation times
→ Domains to find download source

Learn how to corroborate timelines to investigate suspicious TeamViewer.

I'm super excited for this webinar. Sid is a super smart AI / LLM guy and it will be a good session to learn how to use AI in #DFIR and what's hype.

We'll also show Cyber Triage hooked up to an LLM so that you can query artifacts.

Automation is when the tool does the next step for you.

That doesn't mean it does the final step and concludes the investigation. Just a bunch of the needed steps in between. Automation still requires an investigator who asks the right questions and can understand context.

Digital forensics has always relied on automation and "push buttons". What's changed is how many things we automate and the technologies used.

No one ever chose to manually parse FAT12 floppy drives with a hex editor when they could have a tool list out the file names.

3 Ways to Make Digital Investigations Faster with Automation Everyone — except for some consultants paid by the hour — wants to skip the tedious work associated with digital investigation. The good news is there are

Adding automation to your #DFIR investigations means you have less decisions to make. Get rid of the tedious work! Focus on the fun stuff!

Here are my three thoughts on the most effective ways to add automation and which tools do them.

What are yours?

EDR Evasion 101 - Blocking

Data needs to get to the EDR server to be analyzed for attacks. Blocking techniques prevent data from getting to the server.

Example: Network filter to block packets destined to the server.

EDR Evasion 101
Types of Evasion Tactics

1) Blinding - prevent agent from seeing
2) Blocking - prevent data from analysis
3) Hiding - prevent detections

EDRs miss activity! 😲😱.
You should not miss webinar tmrw! 😀

Markus and I will talk about why EDR alerts could be days after an attack started.

We'll talk about how to do endpoint triage to see what else happened beyond the alert!

Alert Triage vs Endpoint Triage: What SOCs Need to Know As we talk to corporate security teams about how they respond to incidents and EDR alerts, we find it useful to highlight the Endpoint Triage step in

For those in the #SOC: Alert Triage vs Endpoint Triage

Blog post that is part of our Endpoint Triage series.

Alert triage focuses on validating and prioritizing the EDR/SIEM alert.

Endpoint triage focuses on prioritizing the host. How bad is it?

Autopsy - Autopsy 4.22.0: BitLocker Support, Cyber Triage Sidecar, Library Updates Autopsy 4.22.0 includes BitLocker support, ability to run alongside Cyber Triage, and updates to lower-level libraries.

New Autopsy release is out! 🎉

It's been a minute, but it's out. Notable features are BitLocker support and it can run side-by-side with Cyber Triage. Plus, a bunch of library updates.

Now Cyber Triage and Autopsy can be used on the same case at the same time!

I'm doing a webinar TMRW on investigation tools for endpoint triage. Basic idea is how to get quick and accurate results after an alert. EDR data plays a role in that, but it's not enough.

Endpoint Triage should be in any security team's process.

I put things like hash lookups to known malware, Yara, Sigma, other types of rules, AI, etc. that assess an items relevance as being automated analysis.

Do you consider that analysis?

I now can't get the image of decorated Prefetch artifacts out of my head. Some goth. Some punk. Some preppy.

3 places to automate #DFIR Endpoint Triage. Which do you do?

Thanks! We were using categories too for a while, but I never knew what to call the things inside the categories. They weren’t artifacts in the traditional sense because we had merged Prefetch etc together. And people were frequently asking us where to find just prefetch.

What term do you use? I've heard a few others at this point.

These can from:
- Data: Raw data that has little meaning on its own
- Information: Processed data that has meaning

Prefetch has meaning only after you realize it means the process ran.

Information Artifacts: Simplify DFIR Analysis Do you know the differences between MUICache, ShimCache, AMCache, and PMCache without the help of Google? Did you know that one of them is made up?

We're using the term "Information Artifacts" for high-level #DFIR concepts like "Processes" and "Inbound Logins". I think they are easier to train than low-level Prefetch, UserAssist etc. (i.e. Data Artifacts). Those map to an Info Artifact (Prefetch -> Process).
