DEATHcon2023: Practical DEATH by Velociraptor
Workshop link DEATHcon Velociraptor workshop was held November 2023. I covered practical break down of Velociraptor and VQL, incorporated into real world scenarios. Brief introduction to Velociraptor and lab setup Available data / VQL accessors VQL Performance and Yara. ATT&CK Detection use case: RDP patching UEFI BlackLotus LNK Analysis
Content Management Like a Boss!
Content management is one of the most under rated Velociraptor capabilities used by mature users. This talk will walk through some basics of content management, introduce automation and hopefully leave you with actionable ideas on how to do Velociraptor Content like a boss. Presentation
Automating Qakbot decode at scale
This is a technical post covering practical methodology to extract configuration data from recent Qakbot samples. In this blog, I will provide some background on Qakbot, then walk through decode themes in an easy to visualize manner. I will then share a Velociraptor artifact to detect and automate the decode process at scale.
Detectraptor

DEATHcon 2022 Velociraptor workshop
DEATHcon Velociraptor workshop was held November 2022. We cover some basic VQL use cases including NTFS, Event Logs, Yara and memory artifacts. The workshop was implemented with Velociraptor 0.6.6 although the data generation can be applied to any version. Data generation scripts Workshop slides Workshop introduction
Notebook and VQL - data munging your way to victory!
Velociraptor notebook is a feature that supercharges analysis and speeds up many components of incident response. New users are often intimidated by advanced VQL and don’t know where to start. This talk aims to shed some light on data manipulation in VQL and provide some practical examples that can be taken away for better artifacts and analysis. Presentation slides Presentation
WMI Event Consumers: what are you missing?
WMI Eventing is a fairly well known technique in DFIR, however some tools may not provide the coverage you expect. This article covers WMI eventing visibility and detection including custom namespaces.
Cobalt Strike Payload Discovery And Data Manipulation In VQL
Velociraptor’s ability for data manipulation is a core platform capability that drives a lot of the great content we have available in terms of data parsing for artifacts and live analysis. After a recent engagement with less common encoded Cobalt Strike beacons, and finding sharable files on VirusTotal, I thought it would be a good opportunity to walk through some workflow around data…
Windows IPSEC for endpoint quarantine
This post is going to talk about using Windows IPSec for a quarantine use case. Im going to explain the background, how to configure a policy and some of the design decisions as I was initially looking at building an endpoint based containment capability.
Local Live Response with Velociraptor ++
In this post im going to talk about a live response use case leveraging the Velociraptor project worth sharing. Specifically, live response with ancillary collection by third party tools embedded to minimise user impact. As usual, im going to provide some background and walk through the steps then share the code.
Live response automation with Velociraptor
This post is going to talk about the Velociraptor project. Specifically, live response and automation I have built for my own engagements. Im going to provide some background and walk through a proof of concept, then share the code.
Endpoint Hunting in an AntiEDR World
With the proliferation of EDR we have seen attackers at all levels upping their game to bypass brittle (and not so brittle) endpoint detection. This talk showcases the background to EDR technology and some practical real world examples of detection bypasses. Download slides Originally presented at a local SANs and community event (modification with additional presentations since).
O365: Hidden InboxRules
In this post Im going to talk about Office365 hidden inbox rules. Im going to give some background, show rule modification, and talk about detection methodology.
Binary Rename 2
This is my second Binary Rename post, in this post I am focusing on static detection, that is assessing files on disk. I am going to describe differences between both Yara and Powershell based detections, then share the code.
Blue Team Hacks - Binary Rename
In this post I thought I would share an interesting proof of concept I developed to detect Binary Rename of commonly abused binaries. Im going to describe the detection, its limitations and share the code.
Live Response Script Builder
In this post I thought I would share some practical new features implemented in a recent refactor of Invoke-LiveResponse. These features enable fast and modular generation of live response scripts compatible with legacy Powershell. Im going to walk through the background then some of the new features and script creation.
Powershell Download Cradles
In this post I thought I would share some information on Powershell download cradles I put together recently. I’m going to provide an overview, highlighting areas I found interesting thinking about detection from both network and endpoint views.
Sharing my BITS
I thought I would share some research on Microsoft BITS after a recent tool released by the French ANSSI to parse BITS job artefacts. This tool has sparked my interest due to previous research on download cradles and an interest in the client side forensics. I’m going to give a brief background, talk about some nuances in collection types and provide some background information when I was thinking…
Invoke-LiveResponse
In this post, I am going to talk about a Powershell module I have authored as a simple implementation for live response and file collections over Powershell remoting. The initial use case was considered after an endpoint vendor appliance failed and capability for raw collections was limited. The module uses Powerforensics over WinRM, and after some interest, I think is worth sharing.
Invoke-LiveResponse
Invoke-LiveResponse is a Powershell module I put together to enable raw disk collections over WinRM and local script execution. Leveraging Powerforensics via a custom Powershell function it enabled collections of key forensic artefacts and stdout of script results typical for live response tasks. See Invoke-LiveResponse on Github
Blue Team Hacks - WMI Eventing
In this post I am going to cover a little Windows Management Instrumentation (WMI), and in particular an interesting use case for potential use in older environments with Process Monitoring gaps. Thinking about this gap led to me looking at WMI starting as an alternate near real time detection fix, and during feature investigation ended with another technically novel solution I thought was…
PowerShell Remoting and Incident Response
PowerShell is quickly becoming a tool of choice for many IT Operations staff and Security Practitioners alike. This post is a quick overview of using Windows Remote Management and PowerShell for Incident Response. I will also provide some proof of concept setup instructions and general themes for those interested in further research on this topic.
