Adrian Dacka
Penetration tester and security researcher focused on offensive security, Active Directory exploitation, and vulnerability research. I build the tools I wish existed — from SQL injection scanners to red-team tradecraft — and lead ThreatVector, a firm delivering hands-on penetration testing.
Security research, offensive tradecraft, and tools built to be used.
I'm a penetration tester and founder based in Poland, working across web, API, and Active Directory environments. My background spans security analysis, freelance security development, and hands-on offensive engagements — grounded by an OSCP and a growing body of public research.
Outside client work, I maintain a set of open-source security tools — scanners, exploits, and tradecraft utilities — used by hundreds of researchers, and I lead ThreatVector, a firm specializing in penetration testing services.
Featured repositories
