Hello there! My name is Ricardo and I am a penetration tester based in Madrid, Spain, with 9 years of experience.
I studied Telecommunications Engineering Degree and a Master’s Degree in Universidad Politécnica de Madrid, where I worked 2 years as researcher. After that I have worked ~8 years as penetration tester/red teamer in Indra, then Entelgy Innotec and now Siemens Smart Infrastructure (Siemens SI).
I will write about open-source tools from my Github or hacking techniques I learn, to have a reference in the future… because I always forget :)
