Hey, I’m Avanthika 👋
I’m a full-time learner and a cybersecurity master’s student. I like exploring the deeper layers of code and security.
I’ve spent the last 4 years in web application security, starting off as a CTF player with:
- Team bi0s — India’s #1 CTF team
- Team Shakti — India’s #1 women-only CTF team
These teams shaped the way I think about problem-solving, exploitation, and security research.
These days, I’m taking learning slowly but deeply, exploring bugs, reading code, experimenting with ideas, and trying to understand things beyond the surface level.
Before starting this blog, I published a write-up here:
🔗 Analysing CVE-2024-24942 leading to unauthenticated Path Traversal
Read my CTF notes here:
I occasionally write technical deep dives on software internals and security.
Updates can be followed via RSS at /feed.xml.
What I’m Into
Most of my curiosity revolves around:
- CVE reproduction and root-cause analysis
- Reverse engineering patches to understand what actually changed
- Java source code analysis and understanding framework internals
- CTFs (web exploitation)
Outside Security
When I’m not reading source code or reversing patches, you’ll find me:
- Reading fiction.(Find me on GoodReads)
- Planning future trips in my head :)
