Before the World Cup even started, the hacktivist group promised to carry out attacks on various websites related to the sporting event, including those of sponsors. Last night, the official World Cup website was taken down and apparently has not been restored yet.
The operation of the website www.worldcup2014.gov.br , which was disrupted by Anonymous, essentially destroys competition for some.
Incapsula, the company that deals with online security and provides protection to various domains, including the domain that received the DDoS attacks, had been waiting for them to happen since the day the major sporting event began.
The fact that the attack was successful surprised the organizers, despite the hackers' warning. In fact, Incapsula stressed that the situation reminds organizations that they should always re-evaluate their security for DDoS attacks, otherwise they risk facing the consequences, as happened now.
Given Anonymous' history of action and attacks, the fact that the World Cup organizers seemingly ignored or were not adequately prepared for the possibility that the hacktivists were not joking is reprehensible. While there is plenty of information about the matches on other sites outside the official World Cup website, it is unfortunate that the official website was taken down and has not been restored after so many hours.
