A hacking group managed to temporarily take down three government websites in Brazil, as well as the site of state oil company Petrobras.
A hackers group called Lulz Security claimed responsibility for the attacks via Twitter.
This came days after an attack on some Brazilian army databases. The hackers took personal details of almost 1,000 soldiers, and released them on Twitter. O Globo newspaper said the attack appeared to have been carried out by a college student.
Meanwhile in Colombia, a group named Anonymous took down the Senate’s website Friday, in protest against a new law to address copyright infringement on the Internet.
The group threatened similar action against the governments of Chile and Peru, via a video announcement. In a project the group called Free Andes the group threatened to launch cyber attacks against government websites if “the governments of Chile and Peru continue to violate the rights of their people, [by] monitoring conversations on blogs, Twitter and Facebook.”
