pystinger

Inglês | 简体中文

O Pystinger implementa proxy SOCK4 e mapeamento de portas através de webshell.

Pode ser usado diretamente pelo metasploit-framework, viper, cobalt strike para sessão online.

O Pystinger é desenvolvido em python e atualmente suporta três scripts de proxy: php, jsp(x) e aspx.

Uso

Suponha que o nome de domínio do servidor seja http://example.com:8080O endereço IP da rede interna do servidor é 192.168.3.11

Proxy SOCK4

• Faça upload de proxy.jsp para o servidor alvo e garanta que http://example.com:8080/proxy.jsp possa ser acessado, a página retorna UTF-8
• Faça upload de stinger_server.exe para o servidor alvo, no AntSword execute cmd start D:/XXX/stinger_server.exe para iniciar o pystinger-server

Não execute D:/xxx/stinger_server.exe diretamente, isso causará desconexão TCP

• Execute ./stinger_client -w http://example.com:8080/proxy.jsp -l 127.0.0.1 -p 60000 no seu VPS
• Você verá a seguinte saída

root@kali:~# ./stinger_client -w http://example.com:8080/proxy.jsp -l 127.0.0.1 -p 60000
