Israel-based security firm RISCO is responsible for monitoring and maintaining hundreds of CCTV security cameras all over the 41,000-seat Arena Pantanal football stadium in Cuiaba, Brazil. The security centre allows security personnel to view live feeds from various cameras around the World Cup stadiums.

The password appears to be “brazil2014” in leet speak.
