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. Besides my interest in security, I enjoy reading about stoicism and philosophy.You can read my blogs and writeups at https://aftabsama.com.

I often deliver technical security content to professional and executive level audiences. For example, as a SOC Analyst at IDDA, I directly presented our SOAR (Security Orchestration, Automation and Response) platform to Ministry of Security representatives. I gave a technical walkthrough of the platform architecture, incident automation workflows, threat correlation mechanisms, and presented real world use cases. Subsequent to the presentation, the product received considerable interest from multiple stakeholders and potential investors.I've also attended vendor meetings with Palo Alto and Forcepoint DLP, presenting technical assessments and making workflow recommendations to help optimize the deployment of security products and their integration into the corporate environment.Besides this type of enterprise-level presentation, I've also been the guy on the team to go to an international hackathon. I presented AI security and automation concepts at an innovation event in Georgia. I gave a presentation to a technical evaluation panel, detailing the design of the system, the model for threat detection, and the architecture of the data pipeline.I also took part in the Google AI Hackathon in Kazakhstan, where I presented a detailed technical pitch including model architecture, implementation strategy, and deployment aspects to judges and business representatives.These occasions implied explaining intricate technical details in a digestible form, addressing immediate technical inquiries, justifying architecture choices, and discussing security compromises. I feel at ease presenting deeply technical information to both engineering communities and business leaders.
