The two hackers publicizing the hackers used the Twitter pseudonyms of Havittaja and The evilc0de; tweeting the infamous line of “tango down” for each attack, a line also used by LulzSec.
The attacks also affected Visa Brazil and MasterCard Brazil, with Visa still suffering downtime. A near complete list of government website attacks have been posted on Pastebin by the hackers with 107 websites taken down by attacking df.gov.br, as the Brazilian government set up websites with sub-domains on the government portal website. However, Havittaja is still tweeting as they bring down websites.
AnonymousIRC tweeted “Brazilians on a killing spree now!” These hacks follow a spate of Anonymous attacks on US entertainment industry and government websites over MegaUpload.com which has been taken down due to alleged piracy charges. One of the hackers involved in the attack, Havittaja, linked to a profile detailing 48 website exploits and “defacement”; with their Twitter tagline saying “yes I’m a defacer”.
