In addition to Citi and Banco de Brasil, by Friday, sites run by HSBC Holdings, Banco BMG, Banco Bradesco, Banco Panamericano, Itau Unibanco Banco Multiplo and Febraban, Brazil's banking federation, also had been hit, allegedly by Anonymous.
Last week, the Brazilian Federation of Banks said it was pushing for a law to criminalize electronic attacks and fraud.
