A CD drive opens on its own, your mouse moves by itself, programs close without any errors, or your printer starts printing out of nowhere? When this happens, one of the first thoughts that may pop into your head is that someone has hacked your computer and is playing around with you. Then you start feeling anger tinged with a bit of fear, because someone is violating your personal space without your permission and potentially accessing your private data. At these times instead of panicking, this tutorial will show what to do and how to potentially help you track down the hacker and report them to the authorities. When your computer is hacked, a hacker will typically install a Remote AccessTrojan, or RAT, that will allow them to gain access to it again in the future.This trojan will listen on a TCP or UDP port and wait for connections from theremote user. Once the remote user is connected they will have full access toyour computer and be able to access files, programs, screen shots, and possiblyyour web cam. While the hacker is connected, though, they are vulnerable because we can useprograms that allow us to see the IP address that the user is connected from.This IP address can be used to find their approximate geographic location,possibly login names from their computer, and identity clues from their hostnames. We can then use this information to report them to the authorities orlaw enforcement. The first step is to proceed to the next section where youwill learn how to use a tool called TCPView to examine the connections betweenyour computer and a remote one. TCPView is a powerful tool for Windows that allows you to see all of the current TCP/IP network connections on your computer. As almost all remote hacks are perpetrated over the Internet, you will be able to use TCPView to quickly spot any remote computers that are connected to your computer. To use TCPView please download it from the following location and save it on your nokia 3310: TCPView Download Link To find a hacker that may be connected to your computer, run TCPView and acceptthe license agreement. You will now be shown a page that displays all of theactive TCP/IP connections on your computer. If there is a remote user connectedto your computer at this time, then TCPView will show their connection and theIP address they are connecting from. When using TCPView always be sure to disable the resolve address feature as wewant to see the connected IP addresses. To do this, when TCPView is open, clickon the Options menu and then uncheck Resolve Addresses. Now that TCPView issetup properly, let's see how TCPView works by looking at a screen shot ofTCPView showing only legitimate connections. Note: Please remember that thereare many legitimate programs that will be legitimately connected to remotecomputers. For example, when you visit a web page with a web browser, you willbe downloading images, ads, javascript, and other applets from all over theworld. Therefore, when you see web browser, messaging program, or otherInternet related program and you recently used it, you should not be concerned. Legitimate TCPView connections As you can see from the image above, the only programs that show an ESTABLISHEDconnection are related to the Internet Explorer process. If Internet Explorerwas just used within the last 5-10 minutes, then these connections arelegitimate connections that were made to various web sites. The processes thatare in a LISTENING state look to be legitimate Windows programs, so they can beignored as well. To be safe, though, you should always check the paths of allLISTENING programs by double-clicking on the program name. This will open asmall dialog that shows you the path to the executable. If the program is inthe proper place then you have confirmed that these are legitimate programs. Now, let's say that you were using your computer and your CD drive ejected onits own. As this is a little strange you should start TCPView and look at itsconnections. Note: Please note that any IP addresses from this tutorial aretotally fictitious and did not perform any harmful activity against anycomputer. TCPView showing a unwanted connection Can you spot the strange connection in the screen above? We see ESTABLISHEDInternet Explorer connections to a variety of hosts, but if you recently usedit then that is normal. At the very top, though, is a strange process calleda.exe that has an established connection to to the remote IP address67.83.7.212 and is listening on the local port number 26666. If you do notrecognize the program or the remote address, then you should immediately becomesuspicious. The next step is to see if there is any legitimate program thatuses that port number. By looking at this Wikipedia Page we see that there isno legitimate program assigned to the 26666 port number. If you are concernedthat you are seeing a suspicious connection, you should definitely write downthe name of the program, its file location, and the remote user's IP address sothat you have it available later. You may also want to take screen shots in theevent you need to show it to the authorities. Finally, we double-click on theprocess name to see where it is located and find that it is stored directly inthe C:\Program Files folder. Process information Executable programs should not be stored directly in the C:\Program Filesfolder, so it paints a stronger case that this is not a legitimate program andthat someone was accessing your computer without your permission. To be safe,you should end the process so that the hacker is no longer connected to thecomputer. Now that you know that someone has been accessing your computerwithout your permission, you should continue to the next section to learn howto use the information we just gathered to track them down Now that you know the potential hackers IP address, you can use that to track them down. The first thing you want to do is get a general geographical location for the user. This can be done using the GeoIPTool site. When you are at that site, enter the IP address for the remote user you saw connected to your computer. GeoIPTool will then display the general location for this IP address as shown below. As you can see from the above image, the remote IP address that connected to your computer is supposedly located in Clifton, New Jersey in the USA. Unfortunately, the GeoIP information is not always accurate, so we want to useanother tool called Traceroute to corroborate what the GeoIPTool showed.Traceroute is a program that will print out the host names of all the devicesbetween your computer and the remote one. As ISPs typically give hosts names totheir devices using geographical names, we can get further clues as to thelocation of the IP address. To use Traceroute you can go to this web site:http://www.net.princeton.edu/traceroute.html. Once there, enter the hackers IPaddress and click on the Go button. A traceroute process can take a while, soyou may want to do something for 5-10 minutes and then come back and check theresults. When done, you should see output similar to what is shown below. Notice the hostname of the last device in the traceroute and the portion that I highlighted. Based upon the information we received from GeoIPTool, this further confirms that the IP address most likely belongs to someone from Clifton, New Jersey. In a real example, though, it will not always be as easy to figure out thelocation of a remote IP address. In those situations your best bet is tocontact the abuse department for the ISP that owns the remote IP address andlet them know what is going on. They will usually issue an alert to the hacker,which if nothing else, will scare them enough that maybe they wont do it again.To find out the name of the ISP that owns the particular IP address, you can goto http://whois.arin.net and enter the IP address in the Search Whois field inthe top right of the home page. This will look up and list the Internet serviceprovider that owns that particular IP address and will usually contain an emailyou can contact. If you plan on reporting this hack to the authorities, youshould avoid contacting the ISP at this time. Finally, someone accessing your computer without permission can be a federalcrime, so if you are truly concerned, you can gather all of this informationand contact your local police department's cyber crime division. If your policedepartment does not have this division then you can contact the FBI Cyber Crimedivision. What you should do once you know you have been hacked Once you know you have been hacked you should immediately harden yourcomputer's security so that it cannot happen again. To do this please performeach of these steps: Change all the passwords for all the accounts on your computer, your email accounts, and any banking accounts. Install all the available Windows Updates. Information on how to do this can be found in this tutorial: How to update Windows If you use Remote nokia 3310, change the port it listens on by using this tutorial: How to change the Terminal Services or Remote nokia 3310 Port Check your programs for available updates using Secunia PSI: How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector (PSI) Use a firewall on your network or your computer. The best line of defense from remote attacks is a hardware firewall such as a personal router. If you only have one computer and the Internet modem is connected directly to your computer, then make sure you enable the Windows firewall. Once you have completed all of these steps, your computer will be much moresecure. Conclusion Hopefully the information in this tutorial will help you to gain control ofyour computer in the event someone hacks it. When reviewing this information,though, it is important to not to jump to conclusions and assume every unknownestablished connection is a hacker. In most cases, connections you see inTCPView are all legitimate and nothing to be concerned about. If you doencounter something that looks suspicious to you, feel free ask us in the techsupport forums. One of our members can help you determine if this connection issomething that you really need to worry about.
