Preetish Chandra Profile Photo

Hi, I'm Preetish Chandra, a passionate and skilled technologist with expertise in ethical hacking and cybersecurity. Currently working as a Cybersecurity Engineer, I'm committed to enhancing software security and contributing to technological advancements.

My Journey

My journey in cybersecurity began with a simple curiosity - I wanted to hack an old Flash game called Club Penguin. This sparked something in me that would change my entire trajectory. I made the bold decision to remove Windows from my computer and switched to Kali 1.0.a, diving headfirst into the world of Linux and ethical hacking.

Using Kali as my daily driver, I immersed myself in learning from null-byte.wonderhowto.com, absorbing everything I could about cybersecurity, penetration testing, and ethical hacking techniques. This self-driven exploration eventually led me to pursue formal training for the Certified Ethical Hacker (CEH) certification while I was still in class 10.

Today, I'm proficient in handling OWASP top 10 attacks and using advanced security tools like Wireshark, Metasploit, BurpSuite, Ghauri, Frida, and Acunetix. My focus is on identifying vulnerabilities before malicious actors do, helping organizations strengthen their security posture through comprehensive assessments and innovative testing methodologies.
