Despite security issues that have plagued Facebook for several years, people keeping staying around and new people keep on signing up. This has led Facebook to break records numbers with over one billion monthly active users as of October 2012—and around 600 million active daily users.
We share our lives on Facebook. We share our birthdays and our anniversaries. We share our vacation plans and locations. We share the births of our sons and the deaths of our fathers. We share our most cherished moments and our most painful thoughts. We divulge every aspect of our lives.
But we seemingly forget who's watching.
We use Facebook as a tool to connect, but there are those people who use that connectivity for malicious purposes. We reveal what others can use against us. They know when we're not home and for how long we're gone. They know the answers to our security questions. People can practically steal our identities—and that's merely with the visible information we purposely give them through our Facebook profile.
The scariest part is that as technology advances, we become more susceptible to hacking. As if we didn't already do a great enough job to aid these hackers, they can get into our emails and Facebook accounts and steal every other part of our lives that we intended to keep away from prying eyes.
And you don't have to be a professional hacker to get into someone's Facebook account.
It can be as easy as letting Firesheep run on your computer for a few minutes. In fact, Facebook allows a user to get into their Facebook without knowing their password. All they have to do is choose three friends to send a code to. You type in the three codes and voilà—you're into the account. It's as easy as that.
These are a few other ways that hackers, and even regular folks, can hack into someone's Facebook account and ways to prevent it from happening to you.
Reset the Password
The easiest way to "hack" into someone's Facebook is through resetting the password. This could be easier done by people who are friends with the person they're trying to hack.
The first step would be to get your friend's Facebook email login. If you don't already know it, try looking on their Facebook page in the Contact Info section.
Next, click on Forgotten your password? and type in the victim's email. Their account should come up. Click This is my account.
It will ask if you would like to reset the password via the victim's emails. This doesn't help, so press No longer have access to these?
It will now ask How can we reach you? Type in an email that you have that also isn't linked to any other Facebook account.
It will now ask you a question. If you're close friends with the victim, that's great. If you don't know too much about them, make an educated guess. If you figure it out, you can change the password. Now you have to wait 24 hours to login to their account.
If you don't figure out the question, you can click on Recover your account with help from friends. This allows you to choose between three and five friends.
It will send them passwords, which you may ask them for, and then type into the next page. You can either create three to five fake Facebook accounts and add your friend (especially if they just add anyone), or you can choose three to five close friends of yours that would be willing to give you the password.
How to Protect Yourself
Use an email address specifically for your Facebook and don't put that email address on your profile.
When choosing a security question and answer, make it difficult. Make it so that no one can figure it out by simply going through your Facebook. No pet names, no anniversaries—not even third grade teacher's names. It's as easy as looking through a yearbook.
Learn about recovering your account from friends. You can select the three friends you want the password sent to. That way you can protect yourself from a friend and other mutual friends ganging up on you to get into your account.
Use a Keylogger
Software Keylogger
A software keylogger is a program that can record each stroke on the keyboard that the user makes, most often without their knowledge. The software has to be downloaded manually on the victim's computer. It will automatically start capturing keystrokes as soon as the computer is turned on and remain undetected in the background. The software can be programmed to send you a summary of all the keystrokes via email.
CNET has Free Keylogger, which as the title suggests, is free. If this isn't what you're looking for, you can search for other free keyloggers or pay for one.
Hardware Keylogger
These work the same way as the software keylogger, except that a USB drive with the software needs to be connected to the victim's computer. The USB drive will save a summary of the keystrokes, so it's as simple as plugging it to your own computer and extracting the data. You can look through Keelog for prices, but it's bit higher than buying the software since you have the buy the USB drive with the program already on it.
How to Protect Yourself
Use a firewall. Keyloggers usually send information through the internet, so a firewall will monitor your computer's online activity and sniff out anything suspicious.
Install a password manager. Keyloggers can't steal what you don't type. Password mangers automatically fill out important forms without you having to type anything in.
Update your software. Once a company knows of any exploits in their software, they work on an update. Stay behind and you could be susceptible.
Change passwords. If you still don't feel protected, you can change your password bi-weekly. It may seem drastic, but it renders any information a hacker stole useless.
Phishing
This option is much more difficult than the rest, but it is also the most common method to hack someone's account. The most popular type of phishing involves creating a fake login page. The page can be sent via email to your victim and will look exactly like the Facebook login page. If the victim logs in, the information will be sent to you instead of to Facebook. This process is difficult because you will need to create a web hosting account and a fake login page.
If you want to know how to do this, follow the detailed instructions on Hacker9's website. Users are very careful now with logging into Facebook through other links, though, so that only adds to this already difficult process.
How to Protect Yourself
Don't click on links through email. If an email tells you to login to Facebook through a link, be wary. Check the URL. If you're still doubtful, go directly to the main website and login the way you always do.
Phishing isn't only done through email. It can be any link on any website. Even ads that pop up can be malicious. Don't click on any sketchy looking links that ask for your information.
Use an anti-virus like Norton or McAfee.
Stealing Cookies
Cookies allow a website to store information on a user's hard drive and later retrieve it. These cookies contain important information that a hacker can sniff out and steal if they are on the same Wi-Fi network as the victim. They don't actually get the login passwords, but they can still access the victim's account.
Firesheep is a Firefox add-on that sniffs web traffic on an open Wi-Fi connection. It collects the cookies and stores them in a tab on the side of the browser.
From there, the hacker can click on the saved cookies and access the victim's account, as long as the victim is still logged in. Once the victim logs out, it is impossible for the hacker to access the account.
How to Protect Yourself
On Facebook, go to your Account Settings and check under Security. Make sure Secure Browsing is enabled. Firesheep can't sniff out cookies on HTTPS, so try to steer away from HTTP.
Full time SSL. Use Firefox add-ons such as HTTPS-Everywhere or Force-TLS.
Log off a website when you're done. Firesheep can't stay logged in to your account if you log off.
Use only trustworthy Wi-Fi networks. A hacker can be sitting across from you at Starbucks and looking through your email without you knowing it.
Use a VPN. These protect against any sidejacking no matter what website you're on.
Less Is More
Social networking websites are great ways to stay connected with old friends and meet new people. Creating an event, sending a birthday greeting and telling your parents you love them are all a couple of clicks away.
Facebook isn't something you should steer away from, but you do need to be aware of your surroundings and make smart decisions about what you put up on your profile. The less information you give out on Facebook for everyone to see, the more difficult you make it for hackers.
