How to protect your Facebook account from hackers, spammers and clowns

If you’re like the average Facebook user, you have 130 Facebook friends.  Those friends may include your mom, your best friend from 5^th grade, your boss. (If your friends list includes people you don’t know, you should audit your account right now. )

Now, what happens if your Facebook account is taken over by a spammer or a scammer? Or maybe a disgruntled ex gets control of your profile and starts posting shameful things on your friends’ walls. Could you brush it off and tell yourself, “It’s just the Internet. Who cares?” Probably not.

Hackers are out there—helping each other to take advantage of lax security. So here’s what you need to know to keep strangers out of your account. If you’re in a hurry, the most important information is on top.

The Basics

Use a strong password and don’t let your browser remember it
Your password is the key to your Facebook castle. If it isn’t strong, if it includes things that your friends and exes can guess, you’re leaving your drawbridge wide open. Creating and remembering strong passwords isn’t easy. That’s why we recommend this simple system.

And tell Firefox, or whatever browser you use, that you don’t want it remembering your passwords. Don’t make life easier for hackers. (To clear your passwords in Firefox, go to “Tools” then “Clear Private Data” the close and reopen Firefox.)

Use unique passwords for all of your important accounts (and update them whenever you go the dentist)
For any account that really matters—your email, your bank and credit card accounts, Facebook—you need to use a unique, strong password that you do not use for any other account. Whenever a site is hacked, you see that this creates a security crisis across the Web. Why? People reuse passwords. Don’t be one of those people.

And yes, you should update the passwords of your most important accounts. How often? Some say every month. Some say every few months.  How about whenever you’ve just gotten home from the dentist? You’ll be in the mood for a little pain. And if you’re the kind of a person who sees a dentist more than twice a year, you should be as careful with your passwords as you are with your teeth.

Of course, if you recognize any suspicious account activity in your account, change your password immediately.

Make sure your system software and Internet security are updated
All the security in the world won’t help you if your PC is infected with a keylogger that can track every letter you type. Updated system and Internet Security can’t stop you from making security mistakes. But it can prevent most of the common attacks out there. Our free Health Check will tell you if your PC is protected.

Watch where you click and watch where you land
Cybercriminals have mastered a devious method of stealing passwords: they ask you for them. This method is called Phishing and it works because it’s easy to make any webpage in the world look official and reputable. A page that looks just like a Facebook profile can be replicated in minutes. That’s why you always need to check the URL in your browser to make sure you’re on Facebook whenever you enter your private information. And if you ever have any doubt about something that has been posted in your newsfeed, follow the Golden Rule of Social Media Securityand don’t click.

Always log out
You’re not keeping hackers out by staying logged in. They still can get in and you’re leaving your account open for a snarky co-worker or invasive family member to pry. And once someone is inside your account, they can change your password to keep you out.

How To Make Sure You Can Get Your Account Back If It Is Hacked

If you start using a new email account, update Facebook settings
If your account is hacked, you need access to the email account you have in your settings. If you can’t get into that email because it’s closed, you’ve just greatly limited your chance of recovering your account.

Do what Facebook recommends
Facebook now rates how secure your account is. It’s a powerful feature, as long as you take it seriously. If your account “Overall Protection” is rated “low”, Facebook will prompt you to add some information. Do this!

Add a secondary email
Facebook asks for a secondary email. This helps Facebook because now it will be able to connect you with more friends. And it helps you if you ever lose access to your primary email, or if your primary email gets hacked. So only add  a secure email account with a unique password.

You can add your secondary email by going to “Account” > “Account Settings”> Find “Email” and click on “change”.

Add your mobile number
Adding your cell phone number gives you a secondary way to claim your hacked account. It also gives you the ability to get one-time passwords, which I’ll explain later. To change or add your mobile number, go here. On that same page, be sure to edit your notifications or Facebook will be texting you nonstop.

Keep in mind that your Facebook account security now depends on your mobile security, so I recommend that you have some way to lock or wipe your phone if you lose it. Our Free Anti-Theft for Mobile does just that.

Add a strong security question
Make sure you choose a question that only you can answer. The last five digits of your driver’s license are probably better answer than the name of your first pet—since your friends and family may know that. The worst answer, of course, would be one that a stranger could figure out by looking at your profile.

For Extra Protection

Activate Account Protection
Want to be notified whenever a new computer logs into your account? Activate Account Protection.

Why would you want to do this? Because if someone gets into your account on a device you don’t recognize, you can login to Facebook and “end activity” on that login. Then you can, hopefully, change your password before the intruder does.

Once you activate this feature, you’ll have to identify ever device you login from. It’s slightly annoying, but it gives you the kind of control of your account that will keep your account safe.

To activate Account Protection and “end activity” on any Facebook sessions you didn’t initiate, go to “Account” > “Account Settings”> Find “Account Protection” and click on “change”.

Use One-Time Passwords on public computers
If you use Facebook on public computers, such as at school or the library, you should use Facebook’s One-Time password feature. On a public computer, you have no idea what kinds of programs are running that could be used to log your account information. By using a unique password each time, you remove the risk that your credentials will be stolen.

To do this you need to set up and verify your SMS number. Go here and add in your mobile number. You’ll then need to verify the number by entering a code that will be sent to you. Once this is done, you can send a text message to 32665 with the message “otp” whenever you’re about to login on a public computer. Your One-Time Password will work for 20 minutes after you receive it.

How to protect your data privacy on social networks

Studies have said public speaking makes as many as 3 out of 4 people anxious. But that was before Facebook.

The 650 million people on Facebook suggest that most of us are getting over—or want to get over—that fear of communicating (or at least sharing pictures) in public. In just a few years, Twitter, YouTube and Facebook have given billions of people the chance to connect to an audience they would never had access to before.

But now that you’re becoming comfortable in public, you may begin to wonder: Am I revealing too much? In a world with the NSA, TMZ and Wikileaks, do I have any privacy? Is it possible to be a public person and still protect my information from being misused?

Friday January 28 is Data Privacy Day 2011, an international celebration of the dignity of the individual represented through personal information. Protecting your irreplaceable data is our mission and we take this mission very seriously. (Here is F-Secure’s Privacy Policy.)

The risks

The more visible, attractive or rich you are, the more you’re a target for the haters, the stalkers and online criminals of the 21st century. Heck, if you have a credit card, you’re a target for both the online criminals and unscrupulous marketers of the world.

Sharing personal information in an age where data can travel faster than lightning requires a 21st century view of data privacy. Some think it’s vain to worry about privacy. But don’t think about your ego, think about social engineering.

Wiktionary describes social engineering as “The practice of tricking a user into giving, or giving access to, sensitive information, thereby bypassing most or all protection.” Criminals have discovered that human error is the easiest vulnerability to exploit. If you’re not careful, your private data (or even public data) can be used to fool you into making mistakes that even your award-winning Internet Security can’t prevent.

Ignorance may be bliss, but it’s not an excuse. Once your private data is stolen, you’ll have to deal with the consequences. The good news is that you can do a lot to make your data more secure

My nephew once told me, “Facebook is so easy that even old people can use it.” And by old people, he meant me.

I agree with my nephew. Most people who use social media don’t suffer significant negative consequences for doing so—or there wouldn’t be millions of new people trying it every day. Stories of people being fired or arrested for what they’ve done on Facebook are rare. But they get lots of attention because Facebook is the superstar everyone knows.

Only a small percentage of those on social media fall victim to the worst of identity theft, malware or scams. And that’s still too many people suffering needlessly—especially because most of these scourges are avoidable.

The lessons

If you learned to manage the benefits and risks of email, you can do the same for social media. Here a few things you can do to help keep your private data private.

1. Decide why you’re social networking.
For some, social networking is an extension of your private life. You mostly interact with people you know or would like to know in the real world. The main topics of conversation are personal. Even when you delve into entertainment or politics or sports, it’s about sharing opinions to have fun and connect. Intimacy is the goal so private things are often shared nonchalantly. For instance, you might reveal what you did on a day when you played hooky from school or work.

For others, social networking is like interacting at a conference. You’re seeking out people in your industry or whom you admire. Conversation is like a cocktail party—being interesting and on-topic matters. When you talk about entertainment or politics or sports, it’s a way to network and establish trust. You want people to feel like they know you, but getting too personal too fast raises red flags. For instance, you may reveal what you did on your vacation but only in a way that you wouldn’t mind your boss reading.

For a growing number of people, social network is a chance to build a little fame or fortune. You’re looking for an audience who trusts and enjoys you to the point you might even sell them things. You converse with fellow influencers and friends but you also broadcast for a targeted or general audience. When you talk about entertainment or politics or sports, you’re entertaining or engaging an audience while establishing expertise. You may share extremely private details or never talk about your personal life. Either way, you’re establishing a persona that’s relatable to the audience you’re trying to attract. For instance, you may reveal a joke a well-known person shared with you.

By the time you’re out of college for a few years, most people have tried out some variation of each of these approaches to social media. And your approach definitely affects your data security.

The rule is: the bigger the audience you seek, the more you have to think about the information you share.

All of us have to protect our ID, account and phone numbers, our address and our Mother’s maiden name. But if you’re an aspiring Disney star or class president, you have to think about which pictures you take—since you know they’ll all be posted eventually. And George Clooney probably shouldn’t use Foursquare to share his location unless he wants to spend his day shaking hands or filing restraining orders.

We all need to be cautious about sharing details that can be used to scam us. If you achieve, or accidentally achieve, fame, your privacy will become even more precious. So if you want to be internet famous, you need to be savvy about which information you share online—or you’ll have to hire people who are.

2. Secure your systems
Don’t use the default password for your voicemail or anything. Use strong, unique passwords for all your accounts. Don’t use work email addresses or passwords for social accounts. Put security software on your PC and your mobile device, if possible. Password protect your Wi-Fi networks.Turn on secure browsing on Facebook. Put a remote lock on your mobile phone. Always lock your PC and mobile devices when you aren’t using them. Keep your system and application software updated. (Our free Health Check makes that easy.) Turn off GPS on your phone and pictures if you don’t want strangers to know your location.

3. Choose services you trust
Any store, service or site that has your data, should have a privacy policy. A key feature of a good privacy policy is that your data will not be shared or sold. By 2011, most reputable online businesses have privacy policies that make that basic promise. But in addition to privacy also have to trust that any organization you trust with your data had security that won’t be compromised. Quality can have a price. If privacy is more important to you than cost, you can buy dedicated email services that won’t serve you ads. Regardless if they charge or not, you should only use reputable online services you trust. Before you enter any data into any website, think, “Do I trust this organization?” If there’s any doubt, ask others what they think.

4. On a social network, your information could be shared with everyone– no matter what your privacy settings are.
Twitter is simple. There are two privacy settings: everyone or “Protect my tweets”. But even if you go with the protected option, your approved followers can still retweet your information to everyone. Facebook’s privacy settings are much more complex. They’re so complex that it almost feels like you should get college credits for really using them. Going with “Friends Only” is a good start, then you have to decide if you want your page on Google (if you don’t want your Facebook page to show up on Google, go to Account > Privacy Settings > Apps and Websites: Edit your settings > Public Search: Edit Settings > Uncheck Enable public search)  and if you want to automatically share your information with other websites.

The safest rule is: get your settings right and still assume that what you post could go public so only share information you wouldn’t mind a future boss (or fan) seeing. NEVER share information that could be used to crack your passwords. Also keep in mind that the information you’re sharing that could be used by identity thieves and social engineers.

5. Be available or don’t
There is a difference between following and friending people. You can follow a lot of people but our brains can only handle around 130 friends. Rejecting or ignoring friend requests can be emotionally difficult, but your privacy is more important than others’ feelings. I say follow anyone on Twitter but on Facebook I’d recommend only befriending people you know or trust. And realize that the person is your friend, not their links. If anyone begins to spam you, let them know the problem. If they keep spamming, unfriend them. If anyone harasses you at all, block their communication. If you’re threatened, contact law enforcement.

You have the right to keep your private data secure while living your digital life to the fullest. All you have to do is respect your own data privacy and do your best to make sure that the people and businesses you interact with do the same.

WiFi + Airport = Lost password

As most travelers know, many airports and VIP lounges offer Wi-Fi connectivity but, unfortunately, these connection are rarely encrypted.   Here’s an example:

All data sent and received travels in clear text, which means anyone could intercept the data for malicious purposes.  This unencrypted data could include passwords, logins, financial information like PIN codes, etc.

Many people also know that it’s always better to use a VPN connection.  However, in many cases,  VPN connection are filtered out and blocked by rules on the network firewall. I tried two different protocols and both were blocked.  Mostly network administrators don’t allow using VPNs from Public WiFi access points only because they want to make sure the network isn’t be used for malicious purposes without any readable network logs.  These policies actually allow to the bad guys to launch really easy  man-in-the-middle  attacks when all traffic pass through a malicious host.

The reality is that using a public Wi-Fi service can expose your really sensitive data to cybercriminals. Recently, we saw some famous people lose their Facebook and other social network passwords by using open (insecure) Wi-Fi connections.

So what is the solution when your VPN is blocked? Well, in some cases, an SSL (https) connection may help. Please, before going to any Website, type in the address bar https:// and then the domain name. After the page is loaded, please check if the certificate used for encryption is a valid one and issued to the site you’re visiting. If you see something wrong with the certificate, stop using the site.

Another solution is to use a cable Ethernet connection instead of a WiFi. Many lounges have such connection as well; it will be much safer for you.

In any case if you’re connected from a public place, it’s better not to use eBanking or ePayment services. That data is the main target for criminals. So, travel safe and keep your personal data safe as well!

iPhone passwords succumb to researchers' attack

Researchers at the Fraunhofer Institute for Secure Information Technology in Darmstadt, Germany, have found a way to steal passwords found in the Apple iPhone's keychain services within six minutes.

In order to steal passwords, the researchers said, the attacker must have have the actual, physical iPhone in hand--this isn't a remote maneuver. First, the attacker has to jailbreak the iPhone, and from there then must install an SSH server on the smartphone to be able to run unrestricted programs. The researchers also created a "keychain access script" that they then copied to the iPhone. After executing that script, they found that they were able to decrypt and see some passwords saved in the keychain.

Over the past year, several iPhone exploits have been revealed by researchers around the world, including some that attack vulnerabilities in the mobile Safari browser. But at least so far, the issues have affected users who jailbreak their own devices. Even in the Fraunhofer Institute's case, a non-jailbroken iPhone will not reveal keychain passwords. Jailbreaking is the process of bypassing the restrictions that Apple sets up to keep users from tinkering with the device's underlying system software.

Researchers said that this latest issue has to do with how iOS handles encryption--namely, that "encryption is independent of the personal password to protect access to the device properly." In other words, even if a user protects access to the iPhone--or any other iOS-based device--with a passcode, it won't be enough to stop hackers from using this method to access saved passwords in the keychain.

It should be noted that the proof-of-concept maneuver would not reveal passwords for Web sites. Services like Gmail, AOL Mail, Yahoo Mail, and others with "protected" passwords "were available to the script only after entering the passcode to unlock the device, which by assumption, should not be possible for an attacker," the researchers noted.

But the folks at Fraunhofer Institute don't necessarily believe that iPhone owners should assume that they will be safe if they don't jailbreak their iPhones. In their scenario, the researchers assumed that the iPhone was stolen and the person who took it knew how to jailbreak the device and create and run scripts. They said in their evaluation of their proof-of-concept that the difficulty level of exploiting the vulnerability is "low."

"Owners of a lost or stolen iOS device should therefore quickly initiate a change of all stored passwords," the researchers wrote in their report. "Additionally, this should be also done for accounts not stored on the device but which might have equal or similar passwords, as an attacker might try out revealed passwords against the full list of known accounts."

Malicious hackers are increasingly turning towardsthe mobile market to target unsuspecting victims.

Earlier this week, security firm McAfee revealed that mobile malware threats were up 46 percent last year. The company said that it expects "cybercriminal activity" in the mobile market to surge in 2011.
