How I Hacked A Remote Computer By Just IP Address

Hacking a remote computer is always a hot topic among hackers and crackers, a newbie hacker or someone who wants to learn hacking always ask these questions that how to hack into a computer by just knowing the IP address. Although we have discussed so many methods before and I always insist to learn some basic commands, protocols and their usage. This is my story like I have hacked into a remote by just using IP address (I have not downloaded any file even I have not cleared the logs). This story was not planned it just happened and I am sure you will like it and you will learn a lot of things if you don't know the basic commands and protocols.

It was Saturday night and I was working hard on social engineering toolkit remote attack (WAN,Internet attack) that is why I was playing with my router for port forwarding and other stuffs, remember my ISP using a dynamic mechanism so I have created DNS server to get the static IP. It was almost night and I have decided to get some sleep and than I have saved my browser tabs so that next time I will use them.

Its Sunday evening I have opened my browser and the previous tabs open automatically and then I got pop up window it asked about the user-name and password of my router I have looked to the address bar the IP address was same as it was saved by me, I was shocked that my ISP has not changed my WAN IP (remember ISP using dynamic IP), after this I have open a website about whatismyip and I have seen that my IP is different it means the window that ask about user name and password is the IP of another computer.

Just got an idea why not to brute force it and get the access on the victim router, hydra has been discussed before, but before brute force I have decided to use guessing technique and I than I have entered so many combination but failed than I just used the default user name and password huurraaah I was in.

Security was very low, than I did a quick nmap scan to get the open ports (remember I have turned off the firewall of victim router). According to the nmap result ftp and telnet was open and then I realized how vulnerable this victim is.
I came across to my terminal and open telnet to the victim by using the default password and I was in and now I was able to take control of this computer but this was not include in the plan.
FTP (file transfer protocol), I came to my terminal again and this time I have used FTP command with the same combination of user name and password and successful. Remember FTP access means you can download and upload files on remote computer means full access. You can use some GUI ftp client but I used command.
Always use a strong password
Turn on your Firewall (both on router and computer)

  1. You must know the various points which hackers use to hack your website. The major point is, IP address. If you surf a lot, hackers may track your site preferences through your IP. They can plan their attack and eventually hack you. One the other hand, MAC address also plays an important role in getting your system hacked.
