Description
In June 2014, during the FIFA World Cup hosted in Brazil, the hacktivist collective Anonymous executed a coordinated cyber campaign dubbed #OpWorldCup (#OpMundial2014, #OpHackingCup, #FreeBrazil), targeting Brazilian government and corporate entities in protest against the tournament’s perceived corruption and social inequities. The attacks, publicly announced in advance, involved data breaches and leaks across multiple high-profile organizations between June 16-17, 2014. Anonymous compromised Globo TV Brasil, one of the country’s largest media conglomerates, exfiltrating and leaking internal data including 167 full names, email addresses, IP addresses, and host details of journalists and employees through a social engineering attack on its website. Simultaneously, the group breached Brazilian federal government systems, leaking names, emails, and hashed passwords belonging to 450 government employees. Tunisian hackers affiliated with the operation separately hacked Cemig Telecomunicações S.A., exposing over 1,000 names and emails of employees and customers, accompanied by a political manifesto condemning corruption and the World Cup’s impact on Brazil.
The campaign expanded to critical infrastructure and judicial entities, including the Regional Electoral Court of the Amazon (Tribunal Regional Eleitoral do Amazonas), where attackers leaked emails and encrypted passwords from its databases. Anonymous also breached Centrais Elétricas do Norte do Brasil S/A (Eletrobras Amazonas Energia), a major northern Brazilian power utility, compromising and publishing names, emails, and telephone numbers of 3,400 users. Additionally, the group infiltrated the Federal Police of Brazil’s official portal, releasing internal screenshots as proof of access. These incidents followed prior disruptions to São Paulo’s Military Police websites days earlier. All leaked datasets were publicly distributed via pastebin-style links, with Anonymous justifying the attacks as acts of solidarity with anti-World Cup protests and dissent against political corruption. No statements from victim organizations regarding incident response, forensic findings, or mitigation efforts were documented in the available reporting at the time of disclosure.
