How to Save Face: 6 Tips for Safer Facebooking

1. Know what you’re getting into
Facebook is a business. It exists to take your online activity and turn it into revenue. Facebook will always be free. But there is a cost. You’re paying by being exposed to advertising and allowing limited disclosure of your online activity.

How limited? You could sit down for a while and read Facebook’s Privacy Policy. But you’ll probably need a few hours and some black coffee.

So here’s a short version: basically everything you post, every person you friend, every group you join will be made public to your “friends”, “friends of your friends” or “everyone”—depending on your privacy settings.

To you this may be simple. You assume that everything you’ve posted could be available to the whole world. Others are still learning. People have lost their jobs as a result of things they’ve posted on Facebook. And when this happens, the newly unemployed person will usually claim that s/he thought that the post was private.

So joining a social network is a leap of faith. On a social network, not only do you have to trust the site to follow its privacy policy, but you also have to trust your friends. Will they reveal your secrets? Will they pass on bad information and scams to you?

And, more importantly, you have to trust yourself to share the right things.

On Facebook, you are exposing your private life in ways you may not even realize. 79% of companies review an applicant’s online information (which is completely illegal in Finland but acceptable in most of the world). Your financial future could depend on how well your profile and your photos and friends list represent you. So think before you post—always.

2. Secure your PC
What does 500,000,000 people on one website look like? To cybercriminals, it looks like a gigantic, unsecured goldmine.

Online gangs and scammers are working twenty-four hours a day to exploit the trust we have for our online friends. Updated Internet security is a must before you use Facebook or any social site. In addition, you have to make certain that your PC is updated with the most recent application system software, which can be time-consuming. F-Secure’s free Health Check makes that easy.

3. Use a unique, strong password
‘Password’ is not a good password. Neither is ‘123456’ or your pet’s name or your name any information that is available publicly on your Facebook profile.

Creating a strong, complex password that you can remember is the key to keeping strangers out of your account. Here’s a simple password system we recommend. You should also use different passwords for your all of your various accounts, especially your email accounts, to keep one hack from becoming a total nightmare.

For extra protection, never let browser remember your password, and lock your PC when you step away from it—especially if you’re living with young children and/or parents and/or anyone, really.

4. Filter your friends
Facebook works overtime to connect you with as many people possible. When you first join, the site combs through your email account to suggest as many people as possible. Then as you use the site it will suggest more email contacts. Email someone new and Facebook will suggest that you become friends.

Run out of contacts, you’ll see friends of friends, brands you might like, your ex.

It’s a strange social dynamic. When see the person’s picture, it feels like this person wants to be your friend. But who knows? All you can be sure of is that Facebook wants you to be friends.

So ask yourself this: Does everyone you email need to be your Facebook friend?

Some people have found that their best friends in the real world make lousy Facebook friends. There are a lot of people who can find you who may not like reconnecting with. According to a recent survey, 70% of Facebook users avoided becoming friends with their bosses.

Maybe you want to limit Facebook to your friends and family and leave professional connections to Twitter and LinkedIn. There’s no perfect formula, but it’s important to have some filter, some limit on what you share with whom. How do you say no when someone you don’t want to offend makes a friend request? Facebook makes this easy. You can just ‘ignore’ the request. That’s a nice way to frame it!

Want to stop Facebook from combing through your email contacts? You can remove your contacts by clicking here. But if you’re using a Facebook app on your phone, first you’ll have to disable the Facebook synchronization feature on your phone.

Want to stop Facebook from suggesting you as a friend to others? Go to “Privacy Settings” click on “Settings” for “Basic Directory Information”.  When you get there, set “Search for me on Facebook” to “Friends Only”.

Always remember this: If anyone solicits you directly about money, assume it’s a scam. Ignore and defriend that profile immediately. An easy way to defriend someone is to go to their profile and scroll down the left column until you find “Remove from Friends”.

5. Click carefully
The biggest dangers on Facebook are the links that appear on your wall. With one bad click, you could end up on a site that attempts to serve you malware or scam you using phishing tactics. One, bad ‘like’ and you could end up spamming all of your friends. That’s why you have to remember that links are not your friends.

The most popular Facebook scams involve gift cards and hilarious videos and diet advice. So far most attacks on the site have been more annoying than harmful. But without vigilance, you can be sure that vicious scams and malware are heading your way.

The best antidote to bad links is Internet security with browsing protection. You can double-check any link before you click it by copying it (right-click on it in Windows) and pasting it into F-Secure’s free Browsing Protection.

Prevention is your best cure. Realize the more sensational or strange or generic a link is, the more likely it is to be malicious. Again, links are not your friends. Apply the same caution you’ve learned to use when you’re checking email to checking Facebook. And just because your friend or family linked something, doesn’t mean you have to click on it.

6. Don’t rely on Facebook to protect your privacy
The whole point of Facebook is to “connect and share with the people in your life.” But there’s a point, for nearly everyone, where all the connecting and sharing can be too much—especially as your information becomes increasingly available to people who aren’t necessarily “in your life.”

So whenever you use Facebook, you have to ask yourself two things: Who do I want to see what I’m doing? And how would I feel if the whole world saw this?

There’s no technical tool to stop your friends from sharing your information. But Facebook does offer you the tools to control who sees your activity. That’s why you need to get to know your privacy settings.

Start at “Account”> “Privacy Settings”. Then click on “Settings” for “Basic Directory Information” . This is where you decide who can find you and what they’ll see when they do.

You get to decide.  How easy do you want to make it to find you on Facebook? Which is more important to you: privacy or connection.

If you’re more interested in connection, select “Everyone” for the top three settings “Search for me on Facebook”, “Send me a friend request” and “Send me a message”. Then consider making all the other settings “Friends Only”. This will encourage people to become your friend, and it gives you more power over your information.

Next you can click back to “Privacy Settings” and set how you share on Facebook.

You can go with the preset options or customize each category individually.

Your safest bet is “Friends Only.” You may want to want to open your activity to “Friends of Friends”; however, there is certain information that you should not make available to “Everyone”. This includes your birthday, your email address and IM, your phone number and address, political and religious beliefs and your family and relationships.

Why? All of this information may be public somewhere else, like a phone book, but you’re simply making too much identifiable information public in one easily accessible place. There may not be enough there for true identity theft, but you are giving a stranger enough information to pose as you online convincingly, which could be a problem if some potential employer or date is checking out your online presence.

You may also want to uncheck the box that says “Let friends of people tagged in my photos and posts see them.” This way you won’t unintentionally draw attention to an image one of your friends may not want others to see.

If you’re very interested in your privacy, you should continue and edit your Application and Website Settings.

Here you should do two things. 1) Remove any applications you aren’t using.  2) Click on “Turn off all platform applications”. Then you can select which applications you don’t ever want to show up on your wall ever again. That’s right. You can say goodbye to FarmVille forever, if you want to.

You can also turn off all platform applications, which will keep your friends from automatically sharing your information with the applications they’re using. Not a bad idea.

Next you can click on “Game and application activity”. Click “Customize” and select “Only Me” to keep all of your Game and application activity to yourself, which is a good idea if you’re friends with people (read: co-workers) who may judge how you spend your time.

After that, take a look at “Info accessible through your friends”.  Here you’ll see all the information that is available to the applications your friends decide to use. That’s right, your friends share all this information automatically with the applications they use.

Once you see that screen, you may want to go back to “Turn off all platform applications”. Why not turn it off until you have a good reason to turn it on?

Now we’re at “Instant Personalization”, which is controversial because Facebook opted all of its users into it. Of course, it warned everyone through an update to its Privacy Policy, but you probably didn’t take the time or coffee needed to figure that out.

So what does Instant Personalization do? It shares your information with three Facebook partner sites: Docs, Yelp and Pandora. Could more partners be added? Yes. Could you just opt out of one or two? Yes. Just click on Docs, Yelp or Pandora and then click on “Block Application.”

Again, unless you know you want to share information with these sites, it’s a good idea to opt out for now.

If you made it this far, you will be rewarded. We are now at, perhaps, the most important Facebook privacy setting: “Public Search”.

You probably heard how recently the information of over 100 million Facebook users was made available for download. All of that information was public before a security researcher took it and turned it into one downloadable file. Those 100 million Facebook users probably had enabled public search.

This is where get to decide if the whole world can find your Facebook profile and information. With one click, your profile could become the top result of a Google search for your name. If you want to avoid disclosure of your information to the world, you may want to start by limiting who can search for you. I recommend that you do not click the box to “Enable public search”.

So those are the tools Facebook gives you to protect your information. They’re complex, and that’s probably on purpose. Facebook is not shy about encouraging it’s users to share and share and share. That’s why you have to remember that Facebook (and your friends) can’t share anything you don’t post to the site.

So be careful not to post anything that can be used against you. This includes travel plans and itineraries,  complaints about bosses, co-workers and customers, company secrets, threats… Has anyone actually had a home robbed after posting plans on Facebook? Yes, indeed.

There are a million things you shouldn’t post. And you are the only person who can decide what you SHOULD share with Facebook and the world. So choose wisely.

Bonus tip: Use Facebook’s one true security feature
Facebook’s one true security feature is simple but powerful. Facebook will inform you anytime any new device accesses your account. That means if some PC or smartphone you’ve never used before logs into your account, Facebook will email you.

To turn this feature on, go to “Account Settings”. Then select “Account Security”.

Just click “Yes ” and then “Submit”.

Now, what do you do if you find out that someone beside you accessed your account? Change your password immediately. On the “Account Settings” page find “Password” and click “change”.

OK. That’s all I know about making Facebook safer a place for you and your friends. For ongoing tips you can follow F-Secure on Facebook. Do you have any tips to add?

The Dukes

“The Dukes” – Ask the Experts

Last week, F-Secure Labs published a new study that provides a detailed analysis of a hacking group called “the Dukes”. The Dukes are what’s known as an advanced persistent threat (APT) – a type of hacking campaign in which a group of attackers is able to covertly infiltrate an organization’s IT network and steal data, often over a long period of time while remaining undetected. The report provides a comprehensive analysis of the Dukes’ history, and provides evidence that security researchers and analysts say proves the various attacks discussed in the report are attributable to the Duke group. Furthermore, the new information contained in the report strengthens previous claims that the group is operating with support from the Russian government. Mikko Hypponen has said that attacker attribution is important, but it’s also complex and notoriously difficult, so the findings of the report have considerable security implications. I contacted several people familiar with the report to get some additional insights into the Dukes, the research, and what this information means to policy makers responsible for issues pertaining to national cybersecurity. Artturi Lehtiö (AL) is the F-Secure Researcher who headed the investigation and authored the report. He has published previous research on attacks that are now understood to have been executed by the Dukes. Patrik Maldre (PM) is a Junior Research Fellow at the International Center for Defense and Security, and has previously written about the Dukes, and the significance of this threat for global security. Mika Aaltola (MA) is the Program Director for the Global Security research program at the Finnish Institute for International Affairs. He published an article of his own examining how groups like the Dukes fit into the geopolitical ambitions of nations that employ them.   Q: What is the one thing that people must absolutely know about the Dukes? PM: They are using their capabilities in pursuit of Russian strategic interests, including economic and political domination in Central and Eastern Europe, as well as the Caucasus region, and a return to higher status at the international level. AL: They are a long-standing key part of Russian espionage activity in the cyber domain. MA: The geopolitical intention behind the vast majority of targets. Q: We now know the Dukes are responsible for a number of high profile attacks, and seemingly target information about politics and defense. But what kind of information might they obtain with their attacks, and why would it be valuable? AL: They might obtain information like meeting notes, memos, plans, and internal reports, not to mention email conversations. In essence, the Dukes aim to be a fly on the wall behind the closed doors of cabinets, meeting rooms, and negotiating tables. PM: The targets of the Dukes include government ministries, militaries, political think tanks, and parliaments. The information that can be gained from these organizations includes, among other things, sensitive communication among high-level officials, details of future political postures, data about strategic arms procurement plans, compromising accounts of ongoing intelligence operations, positions regarding current diplomatic negotiations, future positioning of strategic military contingents, plans for future economic investments, and internal debates about policies such as sanctions. MA: The targets are high value assets. Two things are important: data concerning the plans and decisions taken by the targeted organizations. Second, who is who in the organizations, what are the key decision-making networks, what possible weaknesses can be used and exploited, and how the organization can be used to gain access to other organizations. Q: The Dukes are typically classified as an APT. What makes the Dukes different from other APTs? MA: APT is a good term to use with the Dukes. However, there are some specific characteristics. The multi-year campaigning with relatively simple tools sets Dukes apart from e.g. Stuxnet. Also, the Dukes are used in psychological warfare. The perpetrators can even benefit from they actions becoming public as long as some deniability remains. AL: The sophistication of the Dukes does not come as much from the sophistication of their own methods as it comes from their understanding of their targets’ methods, what their targets’ weaknesses are, and how those can be exploited. PM: They are among the most capable, aggressive, and determined actors that have been publicly identified to be serving Russian strategic interests. The Dukes provide a very wide array of different capabilities that can be chosen based on the targets, objectives, and constraints of a particular operation. They appear to be acting in a brazen manner that indicates complete confidence in their immunity from law enforcement or domestic oversight by democratic bodies. Q: There are 9 distinctive Duke toolsets. Why would a single group need 9 different malware toolsets instead of just 1? AL: The Dukes attempt to use their wide arsenal of tools to stay one-step ahead of the defenders by frequently switching the toolset used. MA: They are constantly developing the tools and using them for different targets. Its an evolutionary process meant to trick different “immunity” systems. Much like drug cocktails can trick the HIV virus. PM: The different Duke toolsets provide flexibility and can be used to complement each other. For example, if various members of the Dukes are used to compromise a particular target and the infection is discovered, the incident responders may be led to believe that quarantines and remediation have been successful even though another member of the Dukes is still able to extract valuable information. Q: Many people reading this aren’t involved in geopolitics. What do you think non-policy makers can take away from this whitepaper? AL: This research aims to provide a unique window into the world of the Dukes, allowing people not traditionally involved with governmental espionage or hacking to gauge for themselves how their lives may be affected by activity like the Dukes. PM: It is important for people to understand the threats that are associated with these technological developments. The understanding of cybersecurity should grow to the point where it is on par with the wider public’s understanding of other aspects of international security, such as military strategy or nuclear non-proliferation. This knowledge is relevant for the exercise of fundamental liberties that are enjoyed in democratic societies, including freedom of speech, freedom of the press, freedom of association, as well as of basic rights such as voting in elections. MA: The geopolitical intent is clearly present in this activity. However, the developments in this realm affects other types of cyber-attacks. Same methods spread. There is cross-fertilization, as in the case of Stuxnet that was soon adapted for other purposes by other groups.   F-Secure’s Business Security Insider blog recently posted a quick breakdown on how the Dukes typically execute their attacks, and what people can do to prevent becoming a victim of the Dukes or similar threats. Check it out for some additional information about the Dukes.

Did a funny test in Facebook? Time to clean the permissions.

You are precious. You are very valuable. At least to companies dealing in advertising and customer profiling. The value of you and your peers make giants like Google and Facebook tick, with a combined revenue of about $78 billion. I’m sure most of you understand this value. But how many are really making smart choices to guard it? If you’re on Facebook, you may have seen posts like this: “Your Friday night. Tina wants to sleep. Jan destroys furniture. Aaron wakes up handcuffed. Wilhelm starts a drinking competition.” Clicking the image takes you to, or a localized version in your own language. Once there you can create your own test that reveals funny things about you and your friends. It’s obvious that these test are more entertaining than scientific. And this site can’t be blamed for lacking fantasy! Who thinks you’re sweet? How many children will you have? Who should you write a love song for? Who of your friends belong in your stuffed animal collection? Stuffed animal collection! OMG. LOL. :) You can find out all this and much more with the tests at The site is operated by a German company named Socialsweethearts, that claim to have over 1500 tests in more than 40 languages! OK, just another funny and harmless site that creates virally spreading posts and cashes in on advertising, you might think. But let’s take a closer look at what’s going on here. Many of the test involve your friends, revealing whom would be or do something. And to provide this they must know who your friends are, right? So it’s perfectly legit when a dialog pops up asking for access to your Facebook account and friends list. Wait! This is where you should stop and think. Let’s rephrase what’s going on. You purchase an automatically generated joke about you and your friends and pay by allowing them access to your friend list and Facebook wall, including all your past, current and future posts. A good deal? No, I don’t think so. And on top of that, you pay with knowledge about all your friends too, but without asking them for permission. Ok, Socialsweethearts is a German company, and Germany has strong privacy laws. I think there is a pretty good chance that this company isn’t misusing your data shamelessly, even if they definitively has the technical opportunity to do so. But this is pure luck. I bet that virtually none of the folks using these tests actually checked the background of the company and made an educated decision to trust it. Did you? But on the other hand. Pretty much all the giants that make billions on our private data are from the Americas. Europe has totally lost this race. A German company entering the same business successfully would be bright news, sort of. Bad news for your privacy but good news from European business perspective. So don’t worry too much if you have used the services on But this is anyway an excellent opportunity to clean up the list of apps that have access to your data. In Facebook, go to Settings and choose Apps in the menu to the left. Now you see a list of all apps and sites that have been granted access. Some of them are no doubt legit, for example apps that should be able to post to your wall. But the permissions will stay when you stop using something. And some permissions are only needed on a one-time basis, but they will stay on the list. belongs to that category and should be erased. Go through the list and remove anything you don’t need. If you see something that you don’t understand the meaning of, it’s safest to remove it too. Permissions can always be added back and apps that lose their permissions will notify you and ask you to grant new permissions. Happy cleaning, Micke   [caption id="attachment_8485" align="alignnone" width="300"] This is what it looks like when want's permission to access your data in Facebook.[/caption]   Images: Screenshots from and
