Summary
Anonymous Brazil conducted DDoS attacks against multiple Brazilian government and Olympic-related websites, including the Ministry of Sport, during the Rio Olympics opening ceremony, causing temporary outages.

Description
On August 5, 2016, coinciding with the Rio Olympics opening ceremony, the hacktivist group Anonymous Brazil launched distributed denial-of-service (DDoS) attacks against multiple Brazilian government and Olympic-related websites. The primary targets included the federal government's official 2016 Games portal (brasil2016.gov.br), the Rio de Janeiro State Government portal (rj.gov.br), the Ministry of Sport (esporte.gov.br), the Brazilian Olympic Committee (cob.org.br), and the Rio 2016 Olympics official site (rio2016.com). These coordinated attacks overwhelmed the sites' infrastructure, forcing several offline during a period of high global visibility. The group publicly claimed responsibility, framing the attacks as a protest against perceived government corruption and misuse of public funds related to the Olympics. Their operational video message explicitly threatened continued actions to "unmask the numerous arbitrary actions" of officials they deemed enemies of the population.
Following the initial disruption, Anonymous escalated operations by exfiltrating and leaking sensitive data from four Brazilian sports confederations: Modern Pentathlon (pentatlo.org.br), Handball (brasilhandebol.com.br), Boxing (cbboxe.com.br), and Triathlon (cbtri.org.br). The leaked CSV files contained personal information, financial records, and hashed user passwords. The group additionally released personal details of high-profile individuals including Rio de Janeiro's Mayor, the State Governor, the Minister of Sport, the Brazilian Olympic Committee President, and three unnamed businessmen allegedly involved in corruption schemes. Anonymous encouraged further disruption by urging supporters to employ Tor anonymity tools and participate in supplementary DDoS campaigns. By August 6, all affected websites had been restored to operational status. This incident mirrored Anonymous Brazil's 2014 protests against FIFA World Cup policies, demonstrating sustained opposition to large-scale sporting events they associate with institutional misconduct.
