I am Nicolas Saputra Gunawan, also known as Brandy, a Cyber Security Analyst at PT. Defender Nusa Semesta (Defenxor).
As an undergraduate cybersecurity student, I am deeply passionate about the field and excel in hands-on challenges. My primary areas of interest include Network Penetration Testing, Endpoint Forensics, Memory Forensics, and Malware Analysis, where I am committed to making a meaningful impact.
I actively engage with the cybersecurity community through participation in Capture The Flag (CTF) competitions and the creation of CTF challenges, specializing in PWN and Forensics. Additionally, I share my knowledge by developing and publishing CTF challenges, machines, and DFIR cases on Github and Medium.
I am also a board member of the international CTF team, ImaginaryCTF, where I contribute weekly PWN challenges and take part in their annual CTF event, hosted publicly on CTFtime.
My current side project is Plaguards
