The FIFA World Cup starts next week in Brazil, and it's already facing its fair share of problems. Stadiums were not built fast enough, and it's been met with fierce resistance over costs.
But that's not all the trouble that's brewing.
Hacker group Anonymous said it has planned a massive cyberattack on the World Cup's corporate sponsors. A hacker told Reuters the plan is to "protest the lavish spending on the soccer games in a country struggling to provide basic services."
The companies on the Anonymous radar are Adidas, Emirates airline, the Coca-Cola Co. and Budweiser.
"We have already conducted late-night tests to see which of the sites are more vulnerable," said the hacker who operates under the alias of Che Commodore. "We have a plan of attack."
The attack will likely come in the form of a DDoS or Distributed Denial-of-Service attack. The basic idea is that the hacker sends so much junk traffic to a site that it can't process legitimate traffic. If the hacker sends enough disruptive traffic, the site may crash entirely.
