IndiaWhat I'm looking for
On Hack The Box, I’ve rooted 27 machines and published 30+ technical writeups documenting service enumeration, exploitation chains, and privilege escalation. I’m ranked #820 globally and am currently working through the CPTS pathway.
I built ReconFlow, a Python CLI tool that runs staged Nmap scans, fingerprints web services, and automates content and virtual-host discovery. I also built and maintain a security portfolio with my machine writeups and security notes.
I’ve practiced web and API testing with Burp Suite, ffuf, sqlmap, and Nmap, and written Python and Bash helpers to automate reconnaissance. My work has covered known-CVE exploitation, insecure deserialization, container and Kubernetes attack paths, and Linux privilege escalation.
