Profile bio

About Willian B.

I'm a natural curious person, and I fell in love with technology when I started playing around with it in 2013. This passion led me to become a professional Pentester, self-taught in Cyber security and Intrusion Testing. I possess skills in attacking Active Directory networks, wireless networks (currently my main focus of study), internal networks, web servers, and other technologies, along with the ability to create technical and executive reports. I am self-taught in both Linux and Windows distributions, network protocols, intrusion into wireless networks, AD intrusion, log analysis, and have intermediate skills in Bash programming, basic knowledge of Python3, and basic knowledge of SQL.I'm familiar with SOC and NOC, error management, and system intrusion abilities. I have participated in training related to ISO 27001, Cyber security by Cisco, Information Security, LGPD, and EXIN ISFS. I have gained practical experience with tools like Kali Linux, Burp Suite, Nmap, NetCat, among others, as well as using OWASP Top 10. I have experience in creating, manipulating, and correcting scripts.If you're a specialist and you're reading this, remember that this description is for Tech Recruiters. Challenge me because you will be surprised! ;D
