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 got into cybersecurity the messy, curious way - hacking games as a teenager to get extra coins and superpowers, then later reverse-engineering ransomwares to understand how they worked. That same curiosity and passion led me to a career in offensive cyber security.In the past 5+ years of work experience across India, UAE & USA, I’ve worked on:• Mobile application penetration testing (Android & iOS)• Web application and API penetration testing• Secure code review across C/C++, Python, Java, Golang, JavaScript, Typescript and C# .NET• Custom Signature Code Analysis (Semgrep, YARA & Coverity CodeXM custom checkers)• Adverserial tradecraft and Cyber threat intelligence• Network and infrastructure assessments with Segmentation penetration tests for cloud and on-prem setups• Software Composition Analysis (Coverity, Black Duck, GitHub Advisories, PlexTrac)• Innovative research & automated pentest tools development (AI, OSINT, Python, Bash script)Currently, I work as a Security Researcher at OnDefend, where I help secure user data of a large-scale social media platform & contribute to U.S. national security.🌟 Key Achievements:• Awarded the first-ever “Magical Mention” as an intern at Equinix for uncovering and reporting multiple critical security misconfigurations. Recognized for investigative persistence, curiosity, and successfully improving internal security workflows through proactive analysis and alerting.• Bug Bounty & Hall of Fame mentions: Tesco, IKEA, SecureLayer7 live hacking event, Accenture, Ericsson, Springer Nature, OSIsoft🔍CVE Research:• CVE-2020-11539 : Access control issue in Tata Sonata Smartwatch• CVE-2020-11540 : Access control issue in Tata Sonata Smartwatch• CVE-2020-25498 : Chained CSRF & Stored XSS vulnerabilities in Beetel router• CVE-2020-35262 : Stored XSS vulnerability in Digisol router👾 Outside of work, I’m always exploring new tools, ways to use AI as leverage in security, hacking techniques & trying to level up. I love building my own custom IoT devices as well as hacking them.🧑‍🤝‍🧑As an active member of 'Women in Cybersecurity', 'Women in Security & Privacy' and 'The Diana Initiative' volunteer at Defcon, I’m also passionate about making cyber security more inclusive and human, especially for women and underrepresented voices.
