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

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.

Alhamdulillah, I recently conducted a training in the Kingdom of Bahrain.

I would like to thank this beautiful country for the trust, support and cooperation during this training and I look forward to the future success of the cybersecurity specialists and my students.

I would like to highlight the special role of my students in promoting cultural heritage and Islamic values, helping to learn the culture and history of this beautiful country.

I would especially like to highlight the hospitality and recommendations for traditional cuisine.

To my great regret, I was unable to visit the beautiful Grand Mosque and this is probably the only problem that should be noted. =^..^=

I wonder how difficult it is to program this with the most realistic physics?
a long time ago I taught children to program PC games and even wrote several 2D adventure games myself

ANY.RUN says: “Process communicates with Telegram (possibly using it as an attacker’s C2 server)" (T1102)

Many thanks to ANY.RUN for API ♥️!
