Hello! 👋

I am Ahmed Elmayyah (AKA Satharus in some places), I graduated from the Faculty of Computer and Information Sciences, Computer Systems Department, Ain Shams University in July 2021. I’m a cybersecurity enthusiast and researcher, tinkerer, and a strong supporter of free/libre software and decentralisation. I currently work as a Hardware and Firmware Threat Research Analyst at HP. Sometimes I do purple-teaming too. I am also a GCFA and an eCRE.

I like cycling, progressive rock, videogames (add me on Steam), electronics and hardware, and computers. Currently, I am currently living in Bristol, England.

"Satharus" was the name of my characters in a couple of RPG games during high school and it just kinda stuck with me.

That's pretty much all there is to it 😃.

My Work

I usually like to tinker with low level programming, reverse engineering, Linux, and hardware and stuff. Here's some of the work I am proud of, in no particular order:

The 4043: A Ben Eater-inspired Turing complete 8Bit breadboard computer using TTL chips, presented in a blog post trilogy which explains computer architecture and how it would map to such a project
Check out some of my Bash Snippets
Full 128-bit AES Encryption written in x86 assembly without using the AES-NI extension. Alongside is the NASM template for writing quick assembly programs
The not so chad shell
The (forever) WIP GDB interface: Disass

Not strictly software, but related:

	//Shift all to the left
	for (int i = cursor; i < currentLength; i++)
	line[i-1] = line[i];

	//decrement the length
	(*currentLength)--;

	//calculate the number of movements needed forward
	int forward = currentLength - cursor;
	//move to the right
	for (int i = 0; i < forward; i++)
	{
	printf("%c%c%c", 27, 91, RIGHT_ARROW + 'A');
	}
	//go back and delete on the way
	for (int i = 0; i < *currentLength; i++)
	{
	printf("%s", "\b \b");
	}

	//move the cursor back
	cursor--;

	//print the new line
	printf("%s", line);

	//Go back to the original cursor position
	for (int i = 0; i < forward-1; i++)
	printf("%c%c%c", 27, 91, LEFT_ARROW + 'A');
	}
