This week the Brazilian arm of the hacker group LulzSec announced they had taken down two Brazilian government websites, including the website of the president. The attack comes after the group Anonymous threatened to take down websites in Chile and Peru.
The Brazilian government says the sites were only down for a few hours and quickly restored. However, the sites appeared to continue having problems as of yesterday morning.
In recent days, LulzSec has threatened to break into government sites and steal sensitive or classified information. If that was the case, it would be a serious attack on the Brazilian government. However, right now this appears to be a simple hacking attack that shut the website down, not a security breach into the government servers.
O Globo reports that a few days ago a separate attack by a local hacker broke into Brazilian Army servers, stole personal information of soldiers, and published that information online. That information included the email logins and passwords for at least 300 soldiers. That is a much more serious breach of security and a real attack that the Brazilian government must take seriously.
