Hello! My name is Matt Suiche. I am an independent researcher, advisor, and investor. I previously served as the Head of Detection Engineering at Magnet Forensics. Our organization was passionately dedicated to justice and protecting the innocent, a mission we embarked on more intensely after the 2022 acquisition of my cybersecurity start-up, Comae Technologies.
My life-long fascination with learning and understanding complex systems first led me to cybersecurity. My teenage years were spent immersed in reverse engineering, which ignited a profound curiosity about technology that continues to this day. I’ve since explored various fields including operating systems architecture, programming languages, virtualization, modern web application development, and generative art. Furthermore, I’ve delved into numerous domains such as privacy, surveillance, forensics, blockchain, and community development among others.
Here is a method I’m using in the next version of Win32DD (1.2), to retrieve MmPhysicalMemoryBlock regardless of the NT Version. The main problem with KDDEBUGGER_DATA64 structure is the version dependency. Then, we have to rebuild this field by ourselves. To retrieve physical memory runs, I’m using MmGetPhysicalMemoryRanges() undocumented function. This function usage had been documented by Mark Russinovich in 1999, in the Volume 1 Number 5 edition of the Sysinternals Newsletter.
Today, I wrote a tool called sym32guid which aims at retrieving all stored Program DataBase (*.PDB File) GUID (Globally Unique Identifier) from a physical memory dump. To do why? The first goal was to use use symbols as additional information regarding unexported functions like the über-famous msv1_0!MsvpPasswordValidate, but it looks it can also be used to detect Virus and Trojan…
The target machine is a Windows Vista SP1 32bits, I’ve installed last week inside a Virtual Machine and I’ve extracted the physical memory dump from the windows hibernation file through SandMan Framework.
X-Ways (WinHex editor) Forensics Beta 2 now includes hibernation file(hiberfil.sys) support for Windows XP 32-bit only. Please notice, Sandman library/framework is an open-source project under GNU General Public License v3 to read and write the hibernation file released 2 months ago…

Ability to decompress Windows XP 32-bit hiberfil.sys files, whether active or inactive, to get a dump of physical memory with all in-use pages from a previous point of time when the computer entered into hibernation, as well as individually carved xpress chunks from hiberfil.
