10/24/2023 • 15 minutes, 40 seconds
DFSP # 400 - CMSTP
This week I am going to focus on a specific remote execution technique that you may see in the wild. Remote execution is important for incident response investigations but also for file use and knowledge investigations, particularly those that conducted due diligence exams for evidence of malware. I have covered remote execution in the past from different angles and I have done so because it is one of the red flags that an analyst should be looking for. In order to be effective in recognizing either an actual malicious execution or the risk of an attempted remote execution you must be reversed in the clever ways attackers attempt to compromise a host using Microsoft applications. The highlight this week will be CMSTP.exe abuse...

DFSP # 399 - Lateral Movement Failed Logon Events
Finding and analyzing failed logons sometimes is just as important as finding suspicious, actual logon activity. Like anything, context is important. Old logon records offer an opportunity to identify not only suspicious activity, but perhaps attempted activity by an attacker. A standard move in the attack chain is to compromise an account and use it to move within the breached environment. However, it doesn't always work as planned for the attacker, and you may find failed activity a valid signal for identifying, malicious actions. This episode, I'm going to take a look at failed logon events from an investigation point of you.

DFSP # 392 - Simulation Training
This week I'm going to talk about tabletop exercises as part of a security training program. I feel that there is too much focus on technical skill training and not enough focus on actual incident management training in the industry. There are plenty of highly skilled professionals that can do DFIR work… However, a roadblock, many organizations and practitioners encounter is in the struggle of how to actually implement their knowledge and skills for a security incident response investigation within a specific organization. They may know what to do, but there are many challenges in identifying actually how to do it when the time comes. I will share my thoughts on how to improve your security program through simulation training…

DFSP # 327 - Persistence Part 1
One of the first things attackers attempt to accomplish on a compromised system is to establish persistence. Unless you are dealing with a denial of service attack, most other attacker goals are centered on maintaining the degree of control over a compromise system in order to use system resources for things like cryptomining or to maintain a foothold to further an attack strategy. This week I am going to talk about a fast triage methodology for persistence, which is one of the first triage strategies I normally recommend for a compromise assessment. Because I am focusing on a fast triage methodology I am going to focus on the artifacts most examiners will have readily at hand and how to make the most of them during the initial pass.

This week is some thoughts on live evidence integrity. Years ago evidence validation was fairly standard with few exceptions. Nowadays it’s more of a challenge when considering live evidence collections either on scene, remotely or even in lab environments where physical level access to your evidence is becoming more the exception. It is something that needs to be part of your collection process as it may impact the reliability of your results.

DFSP # 321 - URL Leaks
This week I will talk about investigating data spill cases involving exposed URLs. This is a typical privacy investigation many incident response teams handle and I thought it would be useful to go over some standard guidelines for handling such cases. To be effective with these investigations you need to know how to determine liability and responsibility, a little Google foo, and a number of odds and ends concerning mitigation, containment and remediation strategies depending on what you are dealing with.

DFSP # 320 - Lateral MM and Event Logs
This week I’m going to cover detecting lateral movement using Windows event logs. This is not the Windows fast triage method I covered in previous episodes. This is more in-depth and focuses on specific attack tools and strategies seen in actual cases. Going into this level of detail is beyond the scope of a typical episode, however there is some research that has very granular details on the tools and methods you can use. I’ll have that coming up right after this.
4/5/2022 • 13 minutes, 11 seconds
DFSP # 319 - Shellbags
This week is a back to basics episode where I am going to cover Windows shellbags. This is a core Windows artifact that gets included in pretty much most every file use and knowledge investigation or any investigation where you’re looking to tie a specific account to directory access activity. Like most Windows artifacts you must know how user interaction affects the artifact in order to properly interpreted it as evidence. You must also be aware of any caveats or pitfalls that may affect your evidence. Spoiler alert, there is a huge one associated with Windows shellbags that I’ll cover at the end of the episode-it’s nothing new but if you’re unfamiliar with it you definitely need to know about it.
3/29/2022 • 15 minutes, 7 seconds

This week it’s back to basics with a Windows artifact for tracking program execution. I’m covering the user assist key which is a mainstay for both live triage and dead box forensics. This artifact is useful for profiling system usage, identifying malware, and general file use and knowledge applications. There are some caveats you need to be aware of and in this episode I’m covering five different experiments to document the effects that different types of user activity had on the artifact. If you want to better understand this artifact and how to work with it stay tuned.
3/15/2022 • 17 minutes, 36 seconds
DFSP # 316 - Cloud Traffic Security
This week I am covering how different common protocols are secured in the cloud.

9/7/2021 • 20 minutes, 44 seconds
DFSP # 289 - Framing Root Cause
As an analyst, it is important to identify root cause and link it back to security governance strategies. This is dealt with through root cause statements typically. What exactly should you be doing for a root cause statement? How important is it? If you produce a findings report you can count on the root cause statement being read. Other parts of the document may be skimmed through, or even ignored, but the root cause statement is going to draw the attention of a variety of different audiences. Therefore this is something you want to get right. In this episode I’m going to deliver a simple approach you can use.
8/31/2021 • 12 minutes, 3 seconds
DFSP # 288 - Max DFIR Impact
Most of my episodes are about computer forensic artifacts and methods.

DFSP # 285 - Linux Malware Triage
This week I wanted to take a break from Windows forensics and talk about Linux malware triage. The Linux platform offers forensic analysts the opportunity to do a very decent job performing malware triage. What I mean by this is that you do not need any special tools installed, all you essentially need is the knowledge of a handful of commands in the ability to make sense of the output. Armed with this, any analyst can do a malware triage quickly and efficiently.
8/3/2021 • 20 minutes, 55 seconds
DFSP # 284 - Fast Triage case study: non-Windows core processes
This week we’re going to take a look at how standard triage methodology can detect advanced attack techniques. Even as a newer examiners, if you learn the standard triage methods that I have covered in the fast triage series, you will find the skills provide ample opportunity to detect all sorts attack activity-even very advanced attack activity. This is because there are natural chokepoints in the attack chain that can be used to your advantage. This week we are going to see the non-Windows core process triage in action through the lens of a very advanced attack dubbed “operation ghost.”
7/27/2021 • 15 minutes, 40 seconds
DFSP # 283 - CSA Cloud Threats 5

This is the next topic in the Windows fast triage miniseries and it aligns with the goal of the entire series, which is to help new or any analyst identify the most accessible artifacts that may be quickly analyzed to find evidence of compromise. So far we have dealt with persistence, suspicious network activity, and suspicious processes. As always, I will provide a simple yet effective approach to work with lateral movement artifacts.
7/13/2021 • 12 minutes, 12 seconds
DFSP # 281 - Fast Triage case study: persistence
This week I’m doing another walk-through to illustrate how standard triage methodology can detect advanced attack techniques. Sometimes as a newer examiner, it’s easy to become overwhelmed with the technical detail necessary to understand and attack. It’s also easy to become discouraged and convince yourself that it’s way too complicated for your current skill set and you may not even feel useful as a team member. This episode is going to dispel all of that and show you how a focus on the standard fast triage method provides all the knowledge you need to detect and advanced breach into an environment.
7/6/2021 • 12 minutes, 34 seconds
DFSP # 280 - Malware Fast Triage
This week I’m covering malware fast triage. It occurred to me that I should revisit this issue for a couple of different reasons. I remember covering this many years ago and I believe that’s why I haven’t thought about doing anything on it lately. However, it does go hand-in-hand with the Windows fast triage series that I am doing. Part of that strategy is to look for “common malware patterns.” In an effort to maximize what the listeners get from the episodes I figured this topic definitely needs to be revisited so that when I use that term, you are at least clear on what I mean by it and the method it represents.

This week is a continuation of the Windows fast triage miniseries. While other aspects of the triage miniseries had fairly contained artifacts to examine, new process triage presents a large and complex landscape to the analyst. I have already broken down a number of effective analysis methods to make this more manageable. This week I focus on key applications to look for during a review. These applications tend to be associated more with malicious activity, at least according to threat intelligence research, so being aware of them and recognizing the potential is important. I also spend some time talking about the nuances of CMD.
