Probably not the easiest, but Phishing is the most effective way of tricking a person to hand you over his most personal information. It works by sending a target a link that will take him to a log-in page that looks flawlessly as Facebook. The moment the target keys in his information, the hacker wins the hacking game. He is now 1 hacked account richer.
So you want to learn the how-to's of Phishing? It is not easy, but is not rocket science too. All you need is a webhosting service where you will duplicate the log-in page of Facebook. A good host to consider for this is the Byethost. Now, you have to register a sub domain that you will use as the Phisher account. But to do that, you need to go to your sub domain's control panel where an htdocs folder can be found in the online file manager option. You need to download that folder and extract the file after. You will then find an index.htm and write.php files in the folder. Use these files in your htdocs to convert your homepage into a duplicate log-in page of the site you wanted to phish. Check your site to verify it is already a phisher account.
The next step is to find a target that you will send the link that will lead him to your phisher log-in page. The moment he logs into your page, you will receive a password.html file that contains the username and password of your victim. This will directly go to your htdocs in your phpnet.us account. Because Phishing can be done simultaneously in multiple accounts, it is being claimed as the best way in hacking Facebook accounts. As a matter of fact, you can send this Phisher log-in page in as many accounts as you want. And you can even design your Phisher message to automatically update the wall of your victim. That way, you will be able to multiply your victims really fast.
The only problem with Phishing is the capacity of the hacker to convince a target. This is why a person of real good intellect and eye for detail is the best candidate for this task. You don't just trick a person, you have to make him believe that he is in a legal site. And if the hacker is not as convincing, or at least his phisher site, the hacker may be in trouble. You see all those notification on your Facebook account, asking you if you want to report a spammer or flag a message. That's one of the site's hack-control techniques. You see, Phishing is effective, but it is the riskiest of all the Facebook account hacking methods.
