sfuzz Usage Example

Fuzz the target server (-S 192.168.1.1) on port 10443 (-p 10443) with TCP output mode (-T), using the basic HTTP config (-f /usr/share/sfuzz/sfuzz-sample/basic.http):

root@kali:~# sfuzz -S 192.168.1.1 -p 10443 -T -f /usr/share/sfuzz/sfuzz-sample/basic.http
[12:53:47] dumping options:
    filename: </usr/share/sfuzz/sfuzz-sample/basic.http>
    state:    <8>
    lineno:   <56>
    literals:  [74]
    sequences: [34]
    symbols: [0]
    req_del:  <200>
    mseq_len: <10024>
    plugin: <none>
    s_syms: <0>
    literal[1] = [AREALLYBADSTRING]

sfuzz

In the same vein as the Generic Protocol Framework, sfuzz is a really simple to use black box testing suite called Simple Fuzzer (what else would you expect?). The goal is to provide a simple to use, but fairly powerful and flexible black box testing utility.
