Hi, My name is Aftab Sama! 👋I'm a cybersecurity researcher. I graduated from Rashtriya Raksha University with a degree in Computer Science and Engineering with specialization in Cyber Security. My interest in Capture the Flag (CTF) competitions helped me secure my first internship at KPMG India, as I was among the top performers in a national CTF competition organized by the KPMG Cyber Security Team. I secured an on-campus internship at Quick Heal, where I had the opportunity to shadow various malware cases and learn about the investigation process. I validated Indicators of Compromise (IoC) for physical samples from CertIN and OTX, and I utilized my Python skills to automate some daily tasks. I also ranked among the top 100 in TCS HackQuest Season 7 Capture the Flag (CTF) competition, which led to an employment opportunity with TCS, where I am currently working as Penetration Tester.My passion for offensive security and penetration testing led me to obtain certifications such as CAPenX, BSCP, CNPen, CAPen, and CEH Practical, among others. I plan to enroll in further offensive security courses in the future.In my free time, I actively participate on HackTheBox and CTFTime and have taken part in several prestigious CTF competitions, winning multiple prizes.
