Bugcon is one of the most popular security conferences in México. I will be attending for the first time this year and I'm very excited. I've heard good things about it and I'm looking forward meeting with some of the infosec folks here in México.
If you are in Mexico city on Feb 2th and 3rd, don't miss out this great event!
