Gscan is a high concurrency scanner based on golang

📕Usage

⬇️Download links: Download

Gscan use --help to show the usage

~ ./Gscan.exe
Gscan [--host address|--url url] [-p port] [-u username|-U filename] [-uf urlfile] [-p password|-P filename] [-m type] [-t thread] [-w num] [-o output_file] [-v]
Examples:
Gscan --host 127.0.0.1 -p 1-65535 -m portscan
Gscan --host 127.0.0.1 -m ssh -u root -P pass.txt
Gscan --url http:https://www.test.com -m urlscan --cookie "PHPSESSID=abc" --header '{"X-FORWARDED-FOR":"test
.com","Referer":"www.baidu.com"}'
Usage:
  -P string
        Select the path to the password dictionary
  -U string
        Select the path to the username dictionary
  -cookie string
        Set cookie
  -f string
        configuration file
  -h    Show help
  -header string
        Set http headers (format: JSON)
  -host string
        IP address of the host you want to scan,for example: 192.168.11.11 | 192.168.11.11-255 | 192.168.11.11,192.168.11.12
  -m string
        Select the type you want to scan.If you don't know the scan type and you can add -show to show all scan types
  -o string
        Save the results of the scan to a file
  -p string
        Specify a password
  -port string
        Select a port,for example: 22 | 1-65535 | 22,80,3306
  -show
        Show all scan type
  -t int
        Set number of threads (default 300)
  -u string
        Specify a username
  -uf string
        Select the path to the url path dictionary
  -url string
        url
  -v    Show details when scanning
  -w int
        Set timeout (default 2)

PS: subdomain,urlscan,authmodule please use the parameter --url to specify the target instead of --host, subdomain and urlscan use -uf to specify the dictionary file but auth use -P.

📌Test

Let's test the speed of each module PS: My CPU host performance is not very good, so the speed may be slower you can use --show to show all scantype:Gscan --show

~ ./Gscan.exe --show
-m
   [mysql]
   [icmp]
   [memcached]
   [ftp]
   [smb]
   [subdomain]
   [redis]
   [auth]
   [portscan]
   [mssql]
   [ssh]
   [postgresql]
   [urlscan]
   [mongodb]

Timeout = 5
Thread = 1000
Passfile = ./password.txt # or use "Password=" to specify a password

PS: If a false positive occurs during the test, you can increase the timeout or lower the thread,it depends on the target host
