Hey, I'm Marmeus.
A cybersecurity engineer who likes to share my knowledge and experiences with others.
In this blog, you will find useful writeups about Hack The Box, TryHackMe, PortSwigger, etc. Furthermore, I talk about my experience getting several certifications, such as OSCP, CRTO and BSCP. Also, you will find guides for using several hacking gadgets on the market and hacking tools that are used daily in the cybersecurity world. Finally, not everything has been written in English; there will be categories that are written in Spanish, like other different posts.
