Hacking collective Anonymous is reportedly planning on taking down a number of major World Cup 2014 sponsors in the coming weeks.
According to a hacker who claims to have knowledge of the group's intentions, Adidas, Budweiser, the Coca-Cola Company and Emirates Airline are all in the group's firing line.
The source, who goes under the pseudonym Che Commodore, told Reuters, "We have already conducted late-night tests to see which of the sites are most vulnerable. We have a plan of attack. This time we are targeting the sponsors of the World Cup."
Anonymous is thought to be unhappy with the sheer amount of money that has been spent on the football tournament, in a view which reflects that of the numerous Brazilian locals who have taken to the streets over recent months to protest their cause.
In a country with such poor general infrastructure and public services, the general consensus is that the authorities have got their priorities completely mixed up.
Last week, Anonymous broke into the systems of Brazil's Foreign Ministry and leaked a number of confidential emails. According to Che Commodore, an individual called AnonManifest carried this out via a phishing attack.
However, an anonymous official said that no important information was compromised.
The build-up to this year's competition has been marred by news of unrest, construction delays and high-profile injuries. While the likes of Radamel Falcao, Franck Ribery, Marco Reus will definitely miss the tournament, Cristiano Ronaldo, Luis Suarez and Diego Costa face a race against time to be fit to play.
Whatever happens on the pitch, Anonymous looks set to make this a World Cup to remember. The competition kicks off on 12 June, with a game between the host nation and Croatia.
