Beacon Object Files (BOFs) in C2 platforms limit developers.

Read NetSPI's blog post to explore a reference design for a new BOF portable executable (PE) concept that bridges the gap between modern C++ development and memory-executable C2 integration.

By making minor changes to command-line arguments, it is possible to bypass EDR/AV detections.

My research, comprising ~70 Windows executables, found that all of them were vulnerable to this, to varying degrees.

Here’s what I found and why it matters:

This ended up being a great applied research project with @d_tranman on weaponizing a technique for fileless DCOM lateral movement based on the original work of @tiraniddo. Excellent work, Dylan!

Success! Claude 3.7 with my IDA Pro MCP server managed to solve the crackme that was previously failing🦾

The trick was adding a convert_number tool and stress to always use it for conversions. It took ~7 minutes to run and the cost was $1.85. Also includes an analysis report.

Excited to release a tool I've been working on lately: ShareFiltrator

ShareFiltrator finds credentials exposed in SharePoint/OneDrive via the Search API (_api/search/query) and also automates mass downloading of the discovered items.

After using Python for so long, I've been trying to switch to GoLang over the last two years just to try something new. I'm finally somewhat confident in being able to write I'd try to create a video series to help others. This is the first video:

Nothing new, but formalized some operator notes on Entra ID/Azure tradecraft I've found to be exceptionally useful on ops. Overlooked this myself for quite some time and thought others in the same boat might find it worth a read! 📖

NTLM relay is still a major threat and is now even easier to abuse. We just added new NTLM relay edges to BloodHound to help defenders fix and attackers think in graphs.

Read my detailed post - the most comprehensive guide on NTLM relay & the new edges:

As this is public now - an alternative to modifying AppIds to make them use the interactive user via the remote registry you can also use a lot of existing CLSIDs which have the interactive user configured and coerce an incoming RPC authentication from loggedon users 😎
