I am one those people that have a very short attention span for technical instructions, so let me try to explain this as shortly and clearly as possible. Just in case you are like me. :) The idea is to use a system that allows you to do 2 things:
1. Remember your passwords through writing a part of it down. The only thing you need to remember is a part that is the same for all your passwords; a pin if you will.
2. Create passwords that are good and strong, unique and can’t be guessed
Here are the step-by-step instructions:
1. Think of a “pin” for your password, this is the part that is same for all of your passwords. The pin should be 3 characters or longer, it could be something like “25!” and this part should be kept secret.
2. For each of the web sites that you need a password for, you create a code that helps you remember what site/service the password is for. For example aMa for Amazon and gMa for gmail.
3. Continue the password with a random set of 4 or more characters, for example: 2299 or xy76. You should use different random characters for your different passwords.
4. Write down parts 1 & 2 on a note and keep is safe so you don’t forget it. In this example you would end up with a note in your wallet with this written down:
5. When using the passwords, add your pin to them. Remember again that the pin should not be written down anywhere! You can decide the location of your pin too. With the example pin “25!” created in the first step we would end up with 2 passwords that could be:
Tadaa, you now have passwords that are unique and can’t be guessed! And of course you only need to remember a part of it! By having unique passwords you can also make sure that even if someone finds out one of your passwords, the others are still safe.
As a final note, should you choose to use this system, you should come up with your own passwords and not use the ones used in this post or in our Lab’s post.
Hopefully I managed to make it sound relatively easy. If not drop me a question below.
The sad killing of British soldier Lee Rigby has been in the headlines lately after release of a report about how authorities handled the case. Publicity was boosted because the committee thinks Facebook is responsible for the killing. They think the social media giant has a clear obligation to identify and report people who plan attacks like this. Just like the fact that phone companies report everybody who are talking about terrorism and the postal service sends a copy of all fishy letters to the Scotland Yard. I’m sure you get the sarcasm. What happened is that British agencies, MI5, MI6 and GCHQ, had identified the killers, Michael Adebolajo and Michael Adebowale, as interesting persons before the attack. They did however fail to investigate properly and apparently made no attempts to get the suspects’ communications from Facebook. There would have been several ways for them to do that, by a direct request from the police to Facebook or by the secret intelligence connections between GCHQ and NSA. Meanwhile Facebook's internal controls had flagged the killers’ communications and automatically closed their accounts. Facebook did however never report this to the British agencies. Which gave the Brits a convenient scapegoat to focus on instead of the fact that they never asked for that data. Ok, so the Brits blame Facebook. Let’s take a closer look at some numbers and what they really are demanding. There’s about 1,6 billion users total on Facebook. 1,3 billion monthly active and about 860 million daily active users. These users share around 5 billion items and send over 10 billion messages every day. This creates a total stream of around 10 million items per hour and 173 000 per second. Quite a haystack to look for terrorists in! Facebook has some 8 300 employees. If every single one of them, Mark Zuckerberg included, would spend their full working day monitoring messages and shared items, they would have to do over 60 items per second to keep up. Needless to say, any kind of monitoring must be automated for volumes like this. Facebook is monitoring its content automatically. Some keywords and phrases trigger actions, which can lead to closure of accounts. This is understandable as no company want to be a safe haven for criminals and many kinds of harmful activities are prohibited in the user agreement. But Facebook is walking a thin line here. Their primary task is not to be a law enforcement agency but to provide a social media service. They must also be well aware of the fact that reporting innocent people to the authorities is highly irresponsible. Commonly accepted practices of justice are not obeyed anymore when dealing with potential security threats and there is no transparency. There are numerous cases where western authorities have detained and even tortured innocent persons, apparently based on some very vague indications. Maher Arar’s case is a well-known example. So the bar for reporting someone must be high. It is easy for an Internet service to throw out a suspected user. They are after all not paying anything and Facebook have no obligation to let them be users. This ensures compliance with the user terms, no criminal activities allowed. But the threshold to report someone is naturally a lot higher. Especially when the volume forces Facebook to make automated decisions. This is not a sign of carelessness from Facebook’s side, it’s because people by default are entitled to communication privacy. It is also a direct consequence of the fact that terrorism suspicions are handled outside the normal justice system in many western countries. You carry a heavy responsibility if you feed innocent peoples’ data into a system like that. Let’s face it. There’s a large number of criminal conversations going on right now both on Facebook and other social services. Many terrorists are also on the phone right now and some are picking up deliveries with items related to planned attacks. Nobody is expecting the phone company to routinely listen in to identify potential terrorists and nobody is expecting the post to check parcels randomly. Facebook may not report every flagged conversation, but they are at least doing something to not be a safe haven for terrorists. Still they are the only of these services that the Brits call a safe haven. Not very logical. The simple reason for this apparent inconsistency is naturally the need for a scapegoat. The British agencies failed to investigate so they need someone else to blame. But there is a more dangerous aspect hidden here as well. Snowden made us aware of the privacy threats on Internet. The wide-spread mass surveillance has so far to a large extent been secret and even illegal. Pandora’s Box is open now and authorities all over the world are racing to get legal rights to mass surveillance, before the large masses understand what it really would mean. Putting pressure on Facebook fits that agenda perfectly. To be fair, one can naturally also ask if Facebook could have done more. A calm and balanced debate about that is welcome and beneficial. The flagged messages is probably quite a haystack too. To what extent is Facebook reviewing those messages manually, and could this process be improved to catch more potential killers? And at the same time avoid reporting any innocent users. To illustrate that this isn’t as simple as many think. People are asking why Facebook didn’t react on stuff containing the phrase “let’s kill a soldier”. Well, this blog post contains it too. Am I a killer because of that? Should this post be flagged and given to MI5? Safe surfing, Micke
Every year Cyber Monday sets new sales records. The Monday after the U.S.'s biggest brick-and-mortar shopping day a year opens the online shopping season with a flood of sales and deals that are often better than what you'll find in person, without the crowds. But whether you're shopping for presents or not during the next month, advertisers and online criminals will assume you are. And if they aren't targeting your wallet, they may be after the private photos and videos we all keep on the hard drives of our computers or devices. Right now, you can get our F-Secure SAFE protection on 5 PCs or devices with 200 GB of free secure cloud storage. Until December 6, we're giving away one free license for SAFE on 5 devices along with 200 GB of storage and a SAFE hoodie for free each day on our Facebook page. Read the the rules and enter now. And while you're shopping on any device, stay skeptical. Stay focused. And keep up the same online shopping and storage hygiene you should be practicing all year long: 1. Make sure your system, browser and security software are patched and protected. If it's software, it requires updates. As developers have become better at reminding you to update your software, there's become more to update. So keep up with your operating system updates and make sure you're running updated security software. 2. Do all your shopping in in one browser. No Java. Our Security Advisor Sean Sullivan advises that you do all of your financial transactions in one browser that you only use for shopping and banking. “Too many tabs open, too many things going on – that’s when you’re most prone to click on a malicious link or download something you shouldn’t have," he said. So use Chrome for surfing and Firefox for the serious stuff. Whichever browser you use for your transactions, you should disable Java in it -- and all your browsers if possible. If a certain website you need to use requires Java, enable it in just one browser that you use only for that site. 3. Stick to stores/sites you trust. Bad grammar and poor design have been the warning signs of malicious sites and emails for years. But criminals are always upping their game. Your best bet is to avoid untrustworthy sites in general, just as you likely avoid unprofessional looking stores and people who randomly try to sell you stereo equipment from their van. Avoid shopping via Google. Go directly to sites you trust and search there. 4. Only shop over a secure connection -- VPN and https. If you're shopping via Wi-Fi, make sure you're on a network you trust or secure yourself with a virtual private network like F-Secure Freedome. This will encrypt your data to protect your passwords and other private data. Freedome also protects you from scams and trackers, which may use your data to sell you things that do not fit your budget. To make sure your data is secure as it's being transmitted, don't enter your private data unless you see you're on a secured connection where the url starts with "https". If you're not seeing that, move on to the next store. 5. Use one credit card for all your online shopping -- or use credit card alternatives. Limit your damages. If your data is captured by a crook, chances are your credit card company will catch any irregularities. However, you still may be left without a card during the holiday season. Using only one card for online purchases also makes it simpler to keep focused on how much you're spending. For extra security, Sean recommends that you see if your bank offers virtual credit card numbers that can only be used once. 6. Check your statements. You do this? Right? If you don't check your statements to make sure all the charges are yours, who will? 7. Do not reuse passwords. It's like putting the same lock on your house, car, boat and safe. Your passwords for your crucial accounts are sacred and need to be unique and strong. This isn't easy, which is why we recommend a password manager. You can use our F-Secure KEY on one device for free. 8. Have a secret email account for online shopping. Sites like Amazon allowing you to use your email for a login, which is convenient. It also means anyone who knows your email, knows your login and is halfway to cracking your account. A simple solution is to use a special email account that you with with no one that you use as login for financial accounts. 9. Back up everything. What's on our devices and PCs is worth more than the hardware themselves because they represent the thing we can never get back -- time. During the holiday season, your phone is filled with memories of celebrations and gatherings that will only happen in that exact way once. So make sure all your devices are backed up, all the time. 10. Use a cloud service you can trust. As you know from the series of nude photos of celebrities released this year, the security of your cloud storage matters. The more people you have trying to hack you, the more your content is at risk. Using a service -- like our younited -- that offers two-factor authentication and is designed to protect your privacy.

Many techie terms in the headlines lately. Supercookies, supertrackers, HTTP headers and X-UIDH. If you just skim the news you will learn that this is some kind of new threat against our privacy. But what is it really? Let’s dig a bit deeper. We will discover that this is an issue of surprisingly big importance. Cookies are already familiar to most of us. These are small pieces of information that a web server can ask our browser to store. They are very useful for identifying users and managing sessions. They are designed with security and privacy in mind, and users can control how these cookies are used. In short, they are essential, they can be a privacy problem but we have tools to manage that threat. What’s said above is good for us ordinary folks, but not so good for advertisers. Users get more and more privacy-aware and execute their ability to opt out from too excessive tracking. The mobile device revolution has also changed the game. More and more of our Internet access is done through apps instead of the browser. This is like using a separate “browser” for all the services we use, and this makes it a lot harder to get an overall picture of our surfing habits. And that’s exactly what advertisers want, advertising is like a lottery with bad odds unless they know who’s watching the ad. A new generation of supercookies (* were developed to fight this trend. It is a piece of information that is inserted in your web traffic by your broadband provider. Its purpose is to identify the user from whom the traffic comes. And to generate revenue for the broadband provider by selling information about who you really are to the advertisers. These supercookies are typically used on mobile broadband connections where the subscription is personal, meaning that all traffic on it comes from a single person. So why are supercookies bad? They are inserted in the traffic without your consent and you have no way to opt out. They are not visible at all on your device so there is no way to control them by using browser settings or special tools. They are designed to support advertisers and generate revenue for the mobile broadband provider. Your need for privacy has not been a design goal. They are not domain-specific like ordinary cookies. They are broadcasted to any site you communicate with. They were designed to remain secret. They are hidden in an obscure part of the header information that very few web administrators need to touch. There are two ways to pay for Internet services, with money or by letting someone profile you for marketing purposes. This system combines both. You are utilized for marketing profit by someone you pay money to. But what can and should I do as an ordinary user? Despite the name, this kind of supercookies are technically totally different from ordinary cookies. The privacy challenges related with ordinary cookies are still there and need to be managed. Supercookies have not replaced them. Whatever you do to manage ordinary cookies, keep doing it. Supercookies are only used by some mobile broadband providers. Verizon and AT&T have been most in the headlines, but at least AT&T seems to be ramping down as a result of the bad press. Some other operators are affected as well. If you use a device with a mobile broadband connection, you can test if your provider inserts them. Go to this page while connected over the device’s own data connection, not WiFi. Check what comes after “Broadcast UID:”. This field should be empty. If not, then your broadband provider uses supercookies. Changing provider is one way to get rid of them. Another way is to use a VPN-service. This will encapsulate all your traffic in an encrypted connection, which is impossible to tamper with. We happen to have a great offering for you, F-secure Freedome. Needless to say, using Freedome on your mobile device is a good idea even if you are not affected by these supercookies. Check the site for more details. Last but not least. Even if you’re unaffected, as most of you probably are, this is a great reminder of how important net neutrality is. It means that any carrier that deliver your network traffic should do that only, and not manipulate it for their own profit. This kind of tampering is one evil trick, throttling to extort money from other businesses is another. We take neutrality and equal handling for granted on many other common resources in our society. The road network, the postal service, delivery of electricity, etc. Internet is already a backbone in society and will grow even more important in the future. Maintaining neutrality and fair rules in this network is of paramount importance for our future society. Safe surfing, Micke PS. The bad press has already made AT&T drop the supercookies, which is great. All others involved mobile broadband providers may have done the same by the time you are reading this. But this is still an excellent example of why net neutrality is important and need to be guaranteed by legislation. (* This article uses the simplified term supercookie for the X-UIDH -based tracker values used by Verizon, AT&T and others in November 2014. Supercookie may in other contexts refer to other types of cookie-like objects. The common factor is that a supercookie is more persistent and harder to get rid of than an ordinary cookie.
