Brazilian President Dilma Rousseff's official blog website was hacked briefly Thursday by someone who posted an anti-corruption message, officials said.
A presidential official said the intrusion occurred between 1:30 and 5:30 am before technicians were able to restore the site.
The hacker, who posted the identity of @DonR4UL or "beleza (cool) hacker," inserted a photo of protesters sweeping with brooms, an allusion to the fight against rampant corruption in the South American nation, local media said.
The blog normally includes official information on the Brazilian presidency and Rousseff's public schedule.
In June, several official sites were hacked and put offline for three days, and access to the presidential website was off for several hours.
