Just linear
Format: Paperback
I appreciate that it helps to organize the chaos of information, but I just used the template verbatim with my manager and it did not go very well. He said this linear approach does not work anymore with high-level corporate audiences. They want to cut right to the chase and start to dig into the deep details. This layout with simple images, even if you just pull away the map and anchor slides, makes the storytelling too much like a story, not giving enough credit to the speed at which certain audiences can and do process data on a slide. It was an interesting exercise and I still think this linear layout works in some cases. Just not if you are trying to communicate business case or other C-suite type of information.

Great book !
Format: Paperback, Format: Paperback
I just finished MAoS – Malware Analysis on Steroids, and all I can say is: WOW.
This book operates on an entirely different level. It’s not just technical knowledge—it’s a complete shift in how you think about malware, reverse engineering, and real-world offensive/defensive operations.
The way Uriel breaks down complex concepts makes you feel understood as a practitioner, while pushing you to see the deeper mechanics behind every technique. Every chapter forced me to rethink things I didn’t even realize I needed to refine. It’s rare to find a book that is both this practical and this transformative.
What I loved most is how hands-on, deep, and empowering the material is. This isn’t a book you skim. I had to stop multiple times just to take notes because the insights were that valuable. It teaches you to think like a real analyst—beyond theory, beyond static patterns, straight into the mindset of true malware research.
If you want clarity, breakthroughs, and a genuine upgrade in your technical intuition—this is the book to read.
Honestly grateful I picked it up. Highly recommended.

Too many screenshot, not detail explain enough, like a lab manual than a book
Format: Paperback, Format: Paperback
Not recommended this book.
This book is approximately 270 pages long, but around 200 pages are comprised of screenshots, including IDA Pro screenshots, Virustotal result screens, lists of function names, and lists of DLL file names.
This book primarily shows you how to use the tools, which are illustrated mainly through screenshots of the tools' screens and results.
This is a well-structured lab manual that guides you through all the necessary screens and steps to locate the flag.
However, there are too many screenshots, and the concept is not explained in detail.
It is expected that you will have a basic understanding to follow the lab manual.
And this is not colour printing, and the photo was resized, making it a bit hard to read the screenshot details.
If you are at the GREM level, you may already be familiar with using the tools.
Unless you want a quick refresher on your lab skills.
