As an example, added simple analysis of standard on block cipher from #Kazakhstan

Of course, this post does not pretend to be a full-fledged academic research, but the concepts and source code can help many who are engaged in practice-oriented research and not just in theory.

I hope this post is useful for malware researchers, C/C++ programmers, spreads awareness to the blue teamers of this interesting encryption technique and analysis tricks, and adds a weapon to the red teamers arsenal.

Happy New 2025 Year! I continue working on my new book for the blue teamers on Threat Hunting, and I am also preparing a new research on IoT hacking and cryptography. I hope my new works will also be useful in the new year.

This post is the result of my own research on using DES-like ciphers on malware development. As usual, exploring various crypto algorithms, I decided to check what would happen if we apply this to encrypt/decrypt the payload.

In the previous examples I created a simple Proof of Concept
of using legit connections via
Telegram Bot API
VirusTotal API and
Discord Bot API for
“stealing” simplest information from victim’s Windows machine.

https://cocomelonc.github.io/linux/2025/02/01/linux-hacking-4.html next post on my blog. This technique is often used in security research, particularly in side-channel attacks where attackers measure access times to infer sensitive data.

If you’re interested in learning more about low-level performance analysis and side-channel attacks stay tuned for future posts!

Translation of the MD MZ book (2-nd edition, ~1000 pages) into Russian (first few chapters), Turkish (390 pages left) and Portuguese (many thanks to Joas A Santos) languages ​​has begun! =^..^= #malware #book #cybersecurity #hacking

All funds raised go towards publishing the hard copy (paper version) of this book (Turkish language). I'm starting a fundraising campaign.

https://cocomelonc.github.io/malware/2025/02/24/malware-tricks-45.html next post on my blog. simple but not less important

Why this is powerful? Of course it’s a simple “dirty” Proof of Concept, but as you can see it works:

-stealthy payload hiding - no direct payload storage, avoids static detection.
-bypasses simple signature-based detection - payload is embedded in an image file.
-completely pure C - no external libraries required!
-foundation for more advanced steganography-based malware!

Alhamdulillah, I have finished translating the book into Turkish but I need help from fellow native Turkish speakers: there may be many semantic and grammatical errors. Please, contact me on LinkedIn. Twitter, Email or Telegram
