Interesting DLL exports

Found a couple of interesting DLL exports while hunting for LOLBAS. Most of these have not been documented as far as I know. There are potentially a lot more out there, the system was behaving strangely when enumerating the list of exports. Unfortunately, I do not know of a good way to ...

Expanding on Pyramid of Pain

I believe most threat hunters would already be familiar with the Pyramid of Pain. Most hunters aim to detect artefacts and tools, as they are higher up the pyramid. However, there is scarce information available to guide them in doing so. Using my red team knowledge, I would like to expand on ...

OSCE review

I have written an OSCP review and a SANS SEC660 review a few years ago. As time passes, I find these reviews harder and harder to write. Over the years, I have learnt on the job, through my own research and through such courses and CTFs. All this prior knowledge has made it very difficult for ...

We have all come across malware which overwrites the Master Boot Record (MBR) of a machine, leaving it unbootable. The code required to overwrite the MBR is surprisingly simple. We will first need to open a write handle to the physical device using the CreateFile API. The MBR is stored in the ...

FLARE-On 6 - Solve vv_max by hand

After looking at the published solutions for FLARE-On 6, I realised that for challenge 11, vv_max, most people used a script to either reverse the AVX functions or to brute force it. My approach was different, I made use of memory breakpoints strategically placed at the address of the arrays to ...
