About Me
Hi 👋🏻! Welcome to my website, my name is Aristofanis, I come from Athens, Greece, and currently live in Copenhagen, Denmark!
I am a Cyber Security Engineer with a focus on Red Teaming and Penetration Testing. I have been working as a Red Team Operator at Danske Bank, where I gained valuable experience performing adversary simulation, vulnerability assessments, and exploitation of various systems such as web applications, databases, servers, printers, and other devices and services.
Before getting into Cyber Security, I gained my BSc in Computer Science and worked in several EU companies as a Web Developer.
Speaker at Conferences
Honeyscanner @BlackHat Europe 2023
I had the privilege to present Honeyscanner at BlackHat Europe 2023. The event took place on the 6th of December 2023 in London, UK. BlackHat is a computer security conference that provides security consulting, training, and briefings to hackers, corporations, and government agencies around the world. It is a very well-known and established event that gathers the best hackers from around the world and having the opportunity to be among them was a phenomenal experience.
Projects
Designed and Developed Honeyscanner as part of my participation in Google Summer of Code 2023.
Honeyscanner is a vulnerability analyzer for Honeypots. Its purpose is to automatically assess the security posture of specific open-source honeypot projects.
It does this by performing a series of passive attacks
- including static code analysis and container scanning, and consecutively it executes a series of active attacks
against a given honeypot instance.
In the end, it provides the tester with a comprehensive security report.
