Me

I am a computer science major Postgrad. I love reading docs, writing blogs, messing up with my computer,

and take pride in fixing it back.

I love being curious about inner workings of an operating system and take pleasure in delving into system security.

My Works

I am a skillful killful developer, yet a curious researcher. I mostly tinker around low level architecture/how the internet works at OSI level/reverse engineering. Some of my footprints:

  • ARM processor emulation on Unicorn Using Unicorn CPU emulator to emulate pico firmware and study assembly. Details

  • Laufeyson, Domain Recon Framework: Laufeyson is a dedicated fast growing Domain Recon framework capable of gathering intel on a domain or an IP. Details

  • Bypassing CSP, File Forensics: A small project focussed on how polyglot files can be taken advantage of in bypassing CSP rules for Reflected XSS attacks. Details

  • GNU toolchain on InterProcess Communication(IPC): Built a semi-system of two processes and studied every possible route of process handling using signals and shared memory segments. Details

  • Deploying application using Voice assistant driven pipeline: A Voice-to-Code implementation where you can deploy/create and feature branch of an applications by completely using Alexa/Google Home. Details

  • Hardware implementation - A Computer from scratch: A project that mainly focuses on building a computer right from scratch, starting from the level of gates to registers, to reaching CPU and the assembler. A hardware based project, have the knowledge of assembly language(8085, 8086, x86, hack). Details

  • DevSecOps-Automation-Monitoring: Contains all types of automation scripts that can be used by Devops practisioners for automating daily workflows. Details

  • Keka Reminder Bot: A bot that is capable of sending scheduled messages (default telegram allows per message scheduling) which works for months with minimal memory consumption. Details

  • New Tab Extension: Built a simple new tab extension that supports chrome and firefox browsers. Available on Firefox Add-ons. Details

Volunteered Contributions in OpenSource

As an indidual who supports and uses FOSS extensively, I have given my contributions in the following:

  • OWASP Maryam, OSINT Framework: Maryam is a dedicated fast growing OSINT framework capable of scraping and gathering large amount of Data. Including subdomains and dns records. A project under OWASP. There are several modules added by me. Details

  • Software Discovery Tool by OpenMainframe Project: Software Discovery Tool helps match developers with the best open source software that meets their needs. Developers can search through open source software for zArchitecture/s390x for any Z operating system from any source, any repo, anywhere, in one place. Details

I Love Working On

Strongly believing on the killful phrase, I continue to venture further in

  • Fuzz testing libraries, reading a emulating assembly with unicorn, reversing malware samples and analysis using FlareVM.
  • Monitoring and Automating Cloud Services workflows. Have worked with various services on AWS and GCP. Experience with IAM, policies and group management.
  • Kubernetes and Docker Security. Secret Management and Rotation using Vault and Cluster hardening using kskan and monitoring using Falco. Proficient in docker environment workflow.
  • Linux kernel enthusiast, writing automation tools in bash and python to make life easier.
