Eid Mubarak 💝

Today I received the 2024 sales report for my book Malware Development for Ethical Hackers. Total sales including ebooks and Packt subscriptions: 1,160 copies. The book was in the top 3 Amazon wishlist last year, and also in the top 3 on Packt in the security and cryptography categories.

First of all, I am grateful to my family, especially my wife Laura. My readers, coworkers, and friends deserve a tremendous amount of gratitude as well.

It is my sincere desire that the information I impart will result in at least one reader becoming more knowledgeable, more proficient, and more self-assured.

In this post I want to show you how to implement custom RC5 encryption in Nim language and execute decrypted payload using a sneaky Windows API trick - EnumDesktopsA

There are already 3 international conferences this year where I will not be able to speak, although I received approval for my talk, and all because of the stupid entry rules into the European Union and the Balkans 😂😂😂

This post is the result of my own research on using TEA encryption on malware development, but the main difference is using Nim language instead C/C++

Djuma mubarak! I know that among my followers on linkedin, twitter and telegram there are French speaking cybersecurity speciialists, I found an interesting playlist and channel: it looks at examples and code from my blog in French on youtube:

Alhamdulillah! Our cat gave birth to kittens! =^..^= 😍

I am working on new book, the book will be released in the next few days in sha Allah

I am on the finish line ❤️
new #book coming soon
#book #malware #hacking #research

https://cocomelonc.github.io/book/2025/05/19/aiya-mmd-book.html

Alhamdulillah, I finished writing this book in few days.
I wrote this book to help my friends:
Nurkhankyzy Aiya, Acute myeloid leukemia (AML).
and all those children who are fighting for their lives.

Why is the book called that? AIYA MMD - means Attack and Introduction or (Android and IOS), start Your Adventure in Mobile Malware Development. also AIYA means AIYA Nurkhankyzy.

I will be very happy if this book helps at least one person to gain knowledge and learn the science of cybersecurity. The book is mostly practice oriented.

Of course the book is not as big as my previous works, this is because firstly I needed to urgently start a fundraising campaign for the Aiya and secondly many things remain confidential (NDA)

Mobile malware - it's a constantly evolving battlefield. What you learned here is just the beginning. Tools change, defenses adapt, but the mindset stays the same: think like the adversary to build stronger defenses.

This book is dedicated to my wife, Laura, and my children, Yerzhan and Munira. I would like to express my deep gratitude to my friends and colleagues.

Special thanks to #Russian #hacking #community, Medet Turin 2600.kz, BlackIce #hackerspace from Almaty (Kazakhstan) and my friends from Middle East countries: Kingdom of Bahrain, Kingdom of Saudi Arabia, UAE.

All examples are practical cases for educational and research purposes only.

I focus on the Speck cipher, a lightweight block cipher developed by the https://x.com/NSAGov

Speck is a family of lightweight block ciphers designed for optimal performance in software implementations. It operates on a Feistel-like structure with simple operations: addition, rotation, and XOR (ARX). Speck supports various block and key sizes; in this example, we’ll use Speck128/128, which has a block size of 128 bits and a key size of 128 bits

https://cocomelonc.github.io/linux/2025/06/03/linux-hacking-5.html next one from my blog. This keylogging trick is used by #apt28 and #apt33 groups in the wild.

Banking Trojans for Linux also often use keyloggers to obtain sensitive data such as passwords for banking applications and cryptographic keys.

I hope this post spreads awareness to the blue teamers of this interesting technique, and adds a weapon to the red teamers arsenal.
