Colaboração: Alexandro Silva
Data de Publicação: 29 de fevereiro de 2008
O Nikto é web server scanner escrito em perl usado para detectar vulnerabilidades em servidores web. Ele é muito simples de ser usado e atualizado gerando relatórios em txt,html e csv.
Baixando o Nikto
wget -c http://www.cirt.net/nikto/nikto-current.tar.gz
Não é necessário fazer a instalação do mesmo pois ele é um script perl.
