ABOUT

A Witch in the Defence Against the Dark Arts

About

I read networks the way Madam Pince reads margin glosses — slowly, suspiciously, and never trusting a packet that won't sign its name. By day a student of cybersecurity and computer science at Hogwarts; by candlelight a tracer of dark arts in traffic and a sworn Auror-in-training of the digital realm.

Aspiring Computer Science and Cybersecurity student with theoretical knowledge in threat intelligence, IoT security, and web penetration testing. Skilled in Python and Wireshark, with experience in network traffic analysis and phishing detection. Seeking to apply and grow in building secure IT solutions.

Defence Against the Dark Arts

Parseltongue for Packets — A Scapy Grimoire

Exploring Network Traffic with Scapy

A grimoire kept in the Chamber: a Python pipeline that captures, classifies, and watches over suspect packets. Open says me.

A Python project to analyse real-time network traffic, gain insights into source and destination activity, and filter and monitor packets based on protocol type.

About

Hi, I'm Devadhashiny.

I'm a cybersecurity engineer focused on threat intelligence, IoT security, and web penetration testing. I read networks the way analysts read margin notes — patiently, layer by layer, never trusting a packet that won't sign its name.

My background spans an internship at the E1 Cyber Crime Police Station investigating live cybercrime cases, and a vulnerability-research internship at Cappriosecurity identifying web-application weaknesses. I'm currently finishing my BE in Cyber Security at Jerusalem College of Engineering with an 8.7 CGPA.

Few apprentices think to whisper lumos. Of those who do, fewer still notice the hint at the corner of the screen. The room appears only when you have real need of it — welcome, and well done.
