Alberto Daniel Hill


I am Alberto Daniel Hill and I am a computer engineer, but in the university I did not learnt anything about security or hacking, I had to learn everything on my own, reading, investigating, and my love for that along with a lot of curiosity and patience gave me a lot of knowledge you could not had learnt in college. For almost 20 years I have been working and gaining experience related to Information Security (Consulting, Computer Forensics, Ethical Hacking, Computer Security). I worked in many large companies in Uruguay and provided services for companies in other countries.

In 2011, I specialized in ISO / IEC-27000 standard as well as ethical hacking and passed various courses related to a wide range of IT security fields. Then in 2012, I specialized in the ISO / IEC-20000 norm.

I am a certified project management professional (PMP) and have led many information security projects since 2011. I also have the Cybersecurity Fundamentals Certificate (CSX) from ISACA, an organization that awarded me PLATINUM membership recognition.

The CSX certification in cybersecurity demonstrates knowledge aligned with the National Institute of Standards and Technology (NIST), National Initiative for Cybersecurity Education (NICE), which is compatible with global cybersecurity topics, activities, and job functions.

I have been part of the volunteer team of the Open Web Application Security Project (OWASP) Uruguay chapter since 2012. I have been recognized all over the world for my knowledge of blockchain and cryptocurrencies, as well as all aspects of their security.

Vardon Hamdiu

Vardon Hamdiu leitet das "Project B" (www.varx.tech). Ziel: Die Demokratisierung der Medien. Die vierte Gewalt kann ihre unschätzbar wichtige Kontrollfunktion nur durch Unabhängigkeit von finanziellen Einflüssen und eine möglichst breite Abstützung der Menschen wirklich wahrnehmen. Dafür braucht es ein grundlegend neues, demokratisches "Geschäftsmodell". Anders als alles, was heute existiert.
