On Wednesday, the Web site of Brazil's defence ministry became a hacking victim. For some 15 minutes, the hackers invaded the site, replacing its original content with pictures of Argentina's revolutionary hero Ernesto "Che" Guevera.
The word "Voltamos", meaning "we're back", was written below the photograph and signed by "Crime Boys".
According to a ministry's spokesperson, this is the first incident of its kind in the one and a half years the site has been in operation. Ministry officials said they do not know who is responsible, but that the incident is under investigation.
