2026-08-27 Exploiting the CVE-2026-31431 in Ubuntu 20.04 This is the first public exploitation that I am performing, because I know that this exploit exists, and know its targets. It is one of the many recent linux LPE exploits that were discovered in 2026 - CVE-2026-31431. This blog is about a complete writeup on how and why this exploit works, everything that's behind it. 2026-08-10 A Quine in the Wild: Reconstructing C from x86-64 Assembly This is my first reverse engineering work, a RE on a binary file named - elf. Though it was hard for the first time doing it, all I had to do is use objdump on that binary and go through raw assembly. Through this, I get an idea on how all these things work. Note that this is a primitive yet interesting binary. 2026-07-28 Hey Neo, What is Matrix Protocol? This is my first blog post, that is about creating a bot group chat in matrix federation used for automating messages, logging, sending files and messages from a victim to a host, providing an overview of matrix protocol and its specifications.

Description

This is a blog post stuff. If I am learning something new, interesting, or if some content intersect the fields of interest, debates, questions based on govt, idealogies and cybersec writeups, you can find those materials here.

There is nothing personal about this blog. Caus leaking information about me will potentially create an information asymmetry. I have spend most of my school time learning school stuffs + most of my holidays learning FIOA docs and consuming lots of analysis reports - though honestly I did not understand them fully, I have got an idea of how to keep things tight - caus in a National Security thing, information disclosure is basically a threat when it comes to a third party :)
