#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.

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.

Brian Carrier @carrier4n6.bsky.social · Aug 13

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.

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.

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.

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!

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

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

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

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.

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.
