Brazil's social security IT company Dataprev is investigating the latest cyber attack to a government's website, the firm said in a statement.
Hackers have breached the Blog do Planalto, presidential blog with updates from President Dilma Rousseff's activities, and posted a photo with people holding brooms and messages against corruption.
Dataprev "has been working on the analysis of the incident by tracing the servers that maintain the blog do Planalto, to verify the causes of the episode," said the company.
After the invasion was detected, the page was temporarily removed and access was reestablished after four hours. Government says blog information and data have been preserved.
This has not been the first hacker attack to government's websites. Since last year, different Brazilian government websites have been affected. Hacker groups managed to breach the websites of the presidency, national geography and statistics institute IBGE, government tax system Receita Federal and various ministries, such as communications, planning and sports.
In order to counter these attacks, government has even announced the plan to create a task force, a cybernetic defense center that would bring together different ministries. The project has yet to be developed, though.
Studies carried out by different IT consultancy firms already pointed to a deficieny in security in most government websites, stating the urgence of deploying stricter measures and of creating IT policies.
