I've started a new personal blog site.
If you are new to Active Directory, these blogs will help you to understand fundamentals of Active Directory, its different components, several AD attacks, concepts behind them & their detections.

🚀 Excited to announce the launch of ExtensionHound! My new Open-Source Tool for Chrome Extension DNS Forensics
Chrome extensions often operate as black boxes, making network activity attribution nearly impossible. Traditional monitoring tools only show traffic originating from the chrome process, leaving security teams guessing which extension is behind a suspicious DNS query.
ExtensionHound addresses this challenge by analyzing Chrome’s internal network state and correlating DNS activity with specific extensions. It’s a purpose-built solution for investigating potentially malicious or unexpected extension behavior.
Key Features:
🔍 Visibility into DNS requests linked to individual Chrome extensions.
🔍 Optional VirusTotal integration for domain reputation analysis.
🔍 Flexible output formats to fit into your workflows.
🔍 Cross-platform support for Windows, macOS, and Linux.
ExtensionHound is designed for incident responders seeking better visibility into browser extension behavior, enabling faster and more precise investigations.

Looking forward to your feedback and contributions!
I am happy to announce JonMon2.0 has been published.
2.0 offers a lot of feature updates, as well as stability. More features still to come as time goes on. Enjoy and let me know if you have any issues or questions.

This strange tweet got >25k retweets. The author sounds confident, and he uses lots of hex and jargon. There are red flags though... like what's up with the DEI stuff, and who says "stack trace dump"? Let's take a closer look... 🧵1/n
Super excited to finally release a project I have been working on for the last few months!
🎊🎊 Introducing the REx: Rule Explorer project and Detection Engineering Threat Report (DETR) 🎉🎉

If you found LoFP from https://t.co/BDnfDwOikI useful, this provides significantly more insights via a much more powerful platform (built on the @elastic stack!)
Happy hunting!

#ProTip: For anyone looking for a temporary virtualized environment for testing malwares or other softwares or even to browse web, Windows Sandbox is a good built-in feature. It is very lightweight, throwaway kind of virtualized environment that provides a secure and isolated space to run potentially unsafe applications or to perform testing without affecting the main system. Software installed inside the Windows Sandbox environment remains "sandboxed" and runs separately from the host machine.
Works on Windows 10/11 Pro and Enterprise editions.
To enable it, go to "Turn on Windows features"> Windows Sandbox
Everything required for this feature is already included in Windows. There's no need to download anything additional.
Close the sandbox and all the software and files and the state are gone. Open the sandbox, and it is ready with a brand new temp environment.
The sandbox can be configured using a .wsb configuration file where you can enable or disable network, add some logon commands and much more.

Wrote a detection tool which analyzes stack and thread metadata to find anomalies and hunt beacons from various C2 frameworks irrespective of sleep masking mechanisms such as Ekko, foliage or timers etc. Detects every c2 framework except ofcourse BRc4. Will publish this post a little polishing. Heres a quick video on it.

The xz backdoor was initially caught by a software engineer at Microsoft. He noticed 500ms lag and thought something was suspicious.
