# Dark Signs Training Mission Tutorial Back to Index Mission Objective: Retrieve the Internal Services Phone Number Starting Link: SECUREDIGITAL.com Welcome to Dark Signs� the object of this short mission is to retrieve the phone number used for Internal Services. This is a training mission designed to teach you some basic commands and skills of the game. NOTE: Whenever you see something written in this font it means that it is a command you type into the console in the game. First we will need to obtain information on our first target, securedigital.com. Type the following command into the game. Scan securedigital.com You will find that there are two �ports�, or two places on securedigital.com that will accept a connection. The default �port� is 80. Type the following command to attempt a connection to securedigital.com on port 80. You can use this command at any time if you for some reason get disconnected. Connect securedigital.com This will connect you to secure digital public interface. Here you can find information on their company, however your aim here is to search through all there data for anything that might be useful. One by one, read all of their information and look for anything that might be useful. Enter 1 and press enter, then the same for 2, 3, and 5. (4 will disconnect you). It is often useful to look closely at the information they have available as any of it might be a key to cracking into their computer systems. The key here is option 5, Administrative services. Looking closely at the SYSTEM ERROR, you come to the realization that hidden in that supposed �random useless data� is a username and password! Notice on line 5 pass-digital, and on line 9; user-secure. You may want to record this information on a file on your own computer. You can do this using the EDIT command once you have disconnected from securedigital.com. Type help edit in the game for more information on this command. So, we now have the following information. Username: secure Password: digital This information seems to relate to the server securedigital.com. Since there is no login options on port 80 of securedigital.com (where you were just connected to), we can now try connecting to any other �ports� that were open on securedigital.com. Looking back at the scan we did of this server earlier, we can see there were two ports open, 25 and 80. Let�s try 25. We can connect to a specific port on a server can be done by typing the port number directly after the server, for example, type the following command. Connect securedigital.com 25 As you will see, your access to this mail server will be denied. It returns the message �ACCESS DENIED � Multiple unsuccessful attempts will be logged automatically�. It is safe to assume the administrators of this server may notice if we keep trying to connect unsuccessfully.� The return message also notes that we were automatically disconnected, as we are not part of their network. Is there a way to somehow, make it look like we ARE part of their network? Proxy Servers can be used to connect to servers in the game, and anonymously. You can use these proxy servers to hide your IP address. When you connect to a server through a proxy server, the target server will only see the IP address of the proxy server, and not your IP address. Let�s think� perhaps there is a proxy server that is part of the secure digital network! There is a command in Dark Signs called trace. You can use this command to display a list of servers that lie between you and a specified server, for example, lets use the trace command on securedigital.com. Trace securedigital.com Using this command shows us there is a secure digital proxy server! Let�s scan it and see what we can do. Scan proxy.securedigital.com Scanning the proxy server reveals that port 109 is open, and running a proxy server. Connect to this port using the following command. Connect proxy.securedigital.com 109 You are connected. It will ask you to enter a destination hostname or IP address. This means it is asking you to enter a server or the IP address of the server. Remember, we want to connect to securedigital.com. So type securedigital.com into the input and press enter once. The proxy server will now ask you to enter a destination port. Enter 25 here and press enter again. If you look back, you will see why we need to connect to port 25 through the proxy server. Before, the connection to securedigital.com on port 25 was denied because we weren�t part of the secure digital trusted network, however the proxy server may give us access. It should verify you, and grant you access! Now, type in the username and password you found at the beginning. If at any time you type something wrong or get disconnected, you may need to go and connect through the proxy server again. You should now be successfully connected to the Secure Digital mail server� Type in secure when it asks for a username, and type in digital when it requests the password. If all goes well, you should see be logged into your email box! Reading the first message, you find no immediately valuable information, however the second email message reveals a username and password appearing to be in an email from our prime target, internal services, located at internalservices.org! Remember the new username and password you have found. Username: sdigital Password: digital Now we know the address of internal services. Let�s have a look at them. Type the following command to scan their server. Scan internalservices.org You should see they are also running a proxy server, however that may not be too useful just now. Lets take a look at their port 80. Type the following command to connect to their machine on the default port, 80. Connect internalservices.org 80 It asks you for a username and password. Lets try the information we found in the email. Enter sdigital for the username, and enter digital for the password. The following information should be displayed. Congratulations� you have found what you were looking for in this mission, the Internal Services phone number! Note that in this training mission, there is no need to do anything with this number.
