If you're hunting for vulnerable XZ instances in Velociraptor: - For Linux, run the Packages artifact and add `WHERE package =~ "xz"` to the default notebook. - For MacOS, list the directory `/opt/homebrew/Cellar/xz/5.6.*` for instances where users have to update/upgrade brew.

Did you know you can use the ETW provider "Microsoft-Windows-DotNETRuntimeRundown" to get a list of loaded .NET Assemblies/Modules/Namespaces? This can be particularly useful for finding malicious DotNet which has been loaded reflectively, using Assembly.Load().

I've just added a Velociraptor Artifact to query this ETW provider, you can grab it here: github.com/Velocidex/velocir…

Forgot to mention this will only work on v0.7.1 onwards, due to the updated ETW library.

It's physically impossible to keep up with the research being released nowadays. Basically life becomes a mix of FOMO, Imposter Syndrome and eventual burnout😭 What's the solution you might ask? Welp it turns out, no one is actually keeping up with everything. 😂Everyone is working on their thing, so keep doing yours.

Hi SIEM vendors, I've noticed you're using Sigma rules from the community GitHub in your products and calling them "Built-In", but you're not giving credit to the authors. It's a simple thing to do and really important for respecting the open-source community's efforts and the Detection Rule License (DRL). Please start crediting the authors and respect the DRL.

While there are many great articles that discuss logs to be sent to a SIEM, many don't mention filtering on the endpoint during investigations. This is an area in which @velocidex excels. 🦖🚀 #FastForensicsBeforeFullSendIt #LogManagementMusts #SaveTheSIEM #SplunkCostBoss

With May being Mental Health Awareness Month, I wanted to take a second to spread some awareness about Transcranial Magnetic Stimulation or TMS. themelbourneclinic.com.au/se…

As someone who has tried multiple antidepressants, but never really found the optimal solution, TMS provided a new path with some incredible results for me. Because it is still new, most doctors I have spoken to had not heard of it, so it's important to spread awareness.

So if you or someone you know is struggling with mental health and medication isn't the right solution for them, encourage them to speak to their doctor about whether or not TMS might be right for them.

Incredible team. You'd be working with not only some of the greatest minds in Australia, but some of the greatest in the world.
If you’re an Aussie who wants to work in vulnerability research, we at @infosectcbr are hiring at all levels, from interns to seniors. DM me for details.

Microsoft IR's (formerly DART) latest blog explores the use of fuzzy hashing in log analysis and introduces JsonHash, a new fuzzy hash algorithm designed specifically for comparing semi-structured data. techcommunity.microsoft.com/…
