Hi, I’m Dave, also known as collfuse. With over 20 years of experience in IT, I specialize in security research and bug bounty hunting. I have a deep expertise in Azure and a broad understanding of various security challenges that organizations face in today’s digital landscape.
My passion for uncovering vulnerabilities and improving systems’ security has driven me to work with companies across industries, helping them strengthen their defenses. As an independent security researcher, I’m always seeking new challenges and ways to push the boundaries of what’s possible. Through my work, I aim to contribute to a safer internet and support organizations in staying ahead of evolving cyber threats. When I’m not hunting for bugs, I’m constantly learning, exploring new technologies, and staying up-to-date with the latest trends in cybersecurity.
I am an active bug bounty hunter on GObugfree, YesWeHack, and Bugcrowd, continuously securing digital assets. In 2024, I achieved third place in GObugfree’s live Bug Bounty event GOHack, proving my skills in real-time cybersecurity challenges
