About Evan Hosinski

I’m an Offensive Security Professional and senior penetration tester who builds, breaks, and improves systems at scale. My work blends hands-on security engineering with a strong focus on real-world tradecraft. I approach security with a paranoid lens and a deep respect for how attackers actually operate, which pushes me to design tools and methodologies that hold up in live environments.I founded KrakenTech LLC, where I build offensive and defensive security platforms used to identify, analyze, and respond to advanced threats. This includes frameworks for phishing, OSINT, payload delivery, large-scale password intelligence, and the real-time detection of native-language exploit attempts. I specialize in designing distributed architectures, writing high-performance security tooling, and solving the kinds of problems that don’t have off-the-shelf answers.My experience spans custom malware and payload development, infrastructure penetration testing, protocol abuse research, and offensive automation. I work across Python, Go, C, C#, C++, PowerShell, and shell languages, with additional experience in languages like Nim and Zig. These tools help me model realistic adversaries and deliver targeted, high-impact findings that reflect the actual risks organizations face.I’m also a technical leader on my team. I mentor other operators, share offensive techniques, and help shape strategies that push engagements beyond checkbox testing. My goal is simple: deliver clear, actionable security improvements by combining engineering depth with practical offensive expertise.If you’re interested in offensive tooling, adversary simulations, or improving detection in complex environments, I’m always open to talking shop.
