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.

Ailin Castellucci’s speaking experience spans key cybersecurity communities and public forums across Latin America, where she delivers both technical workshops and high-level talks focused on practical, real-world security.She has been part of conference lineups such as NotPinkCon, where she presented “Cyber-Operation,” exploring cybersecurity and cyber conflict concepts in an accessible, audience-friendly way.At Congreso AGETIC 2023 (Bolivia), she led a hands-on workshop, “Threat Modeling in a Nutshell,” designed to help teams apply threat modeling methodologies in practice—covering strengths, real-life use, and the human challenges organizations face when implementing these practices. In the same event, she was also listed as a keynote speaker with “Avengers, assemble! – Seguridad colaborativa,” reinforcing her emphasis on collaborative security approaches.She has also spoken at the “Cibercrisis” conference series by Sombreros Blancos, where she presented a talk titled “Roses are red, violets are blue… there’s a spy in your net and she’s behind you!”, bringing an engaging, story-driven angle to security awareness and adversarial thinking.Beyond large events, Ailin frequently speaks in community and online formats—such as Discord sessions—on topics like “Seguridad Colaborativa,” aiming to bridge the gap between security best practices and what teams can realistically implement.Overall, her speaking style blends practitioner experience (offensive security, bug bounty, and security teams) with clear frameworks and actionable guidance, making her talks useful for both newcomers and experienced professionals.
