For a couple of years I was colaborating with DeltaHacker as a Magazine Editor for penetration testing and cyber security technical topics, under my Cr0wTom alias. I wrote 10 articles in total, for which you can find abstracts of the article in my blog, in Greek.

DeltaHacker alongside my personal blog, can be considered my start in the security industry, my first steps and some really exciting times with people from the Greek hacking community that I really apreciate. Cheers to the old, to the colorfull times and to the start of an awesome journey. :)
