In the last few months we’ve been tracking a common technique being used by attackers: They hack a web site and use that as part of their link farm to build page rank for them on search engines. We posted many articles about similar spam issues in the past.

Recently, we’ve started to notice a lot of government web sites from Brazil in this list.

Some are fairly big sites:

http://www.ibama.gov.br – Environmental Ministry
http://www4.planalto.gov.br – Old Presidential Web site
http://www.inmetro.gov.br – Quality control ministry
http://www.cnen.gov.br – Nuclear Energy Commission
http://www.fazenda.sp.gov.br – Treasury from the state of Sao Paulo
http://inpa.gov.br – Amazon research institute
http://www.jfal.gov.br/ – Alagoas Federal Justice
