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 am currently working as a DFIR Engineer at Cyber Castle. Sometimes I do purple-teaming too. I am also an eCRE.
I like cycling, progressive rock, videogames(add me on Steam), electronics and hardware, and computers. Currently, I am living in Cairo, Egypt.
"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
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:
- 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:
- My dot files.
- EOI 2019 Competitive Programming Sessions for middle schoolers.
- Open Source Community FCIS Linux Workshop 2019 content.
