The Defcon Porto Alegre started in 2019 to connect the local infosec geeks to fight the causes of systems insecurity, share the knowledge and techniques with individuals and organisations in order to reduce the cyber security skill gap, promote ethical hacking, responsible disclosure and have fun!

We are open to all curious minded folks, no matter the level with computers or technology.
This is about community, so come out and meet your neighbors, peers, and those running the world in their own minds.

def _About (defcon_groups):

DEF CON Groups (DCGs or DC-Groups) are a gathering point for folks interested in the alternate applications of modern technology, referred to properly as 'hacking'. DCGs are not intended to compete with any other computer groups, such as 2600, but rather to provide yet another gathering place for the discussion of technology and security topics.

DCG meetings are open to anyone, regardless of their skill, age, job, gender, etc. DCGs are designed to help you learn new things, meet new people, mentor others in areas you may be strong in, and provide some cohesion within the hacker culture and it's members.

def _About (call_for_papers):

The DEF CON Groups were spawned from the annual DEF CON security conference in Las Vegas.

If you have something interesting to say, just hit us up with your paper or research! What we need is your skills, experience, and knowledge.
