free good or bad

Free – good or bad?

It’s always nice to get something for free. Or is it? There are really some free lunches on the net. But what appears to be free can have a hidden price, which often is paid by other means than money.

Internet did for a long time lack payment models and everything on the net was truly free. This was fine on a net that was an academic tool and playground for enthusiasts. Our Internet of today is totally different, and to a large extent business driven. But the culture of getting stuff for free on the net is deeply rooted. People are used to free stuff, or are hesitant to use payment on the net in fear of fraud. This has created a lot of new business models based on free products and services. Either genuinely free or with a hidden compensation. One of the important skills for today’s cybercitizens is to recognize these business models and understand the hidden risks and compensations. Read on to learn how.

Before you take the bait you should always ask yourself: Why is this thing offered for free? That’s the key questions as the vendor’s motives dictate if the product or service is safe to use. First look for info about who made the product and why. Then try to place it in one of the categories below. Now it will be a lot easier to make an educated guess about how safe it is.

Ad-financed

A very common way to provide free products or services. Ads are showed to you and the vendor gets money from the advertisers. Be careful with ad-ware your children are using. You have no control over the ads and some content may be unsuitable. Otherwise these are mostly legit if you don’t find the ads too annoying.

User profiling

“If you don’t pay for the product, then you ARE the product.” This is taking ad-ware to the next level. Big data companies like Facebook and Google offer their services for free, but create extensive profiles over their users and utilize them for marketing purposes. This is a privacy problem as you have no control over what data they collect and how it is (mis)used. Intelligence agencies are on top of that also eager to tap into your data. If Facebook knows something about you, then NSA knows too. The problem here is that it is very hard to know what price you really pay for the “free” service. You should consider if the privacy risk is worth taking for the value you get in return.

Hobby and ideological

Many create programs and web services for fun. Giving it away and seeing that people really use it is part of the joy. Some may also have ideological motives, like fighting corporate dominance, guarding peoples’ privacy or defeating net espionage. Products in this category are genuinely free and there’s no hidden compensation. The Firefox browser is an excellent example. The Linux operating system is another.

This “business model” is safe for the customer, but the products and services may not always be the safest choice technically. Providing safe software is a tough task and requires constant maintenance. Hobbyists are not always professional enough for this. In this category you will find a wide range of products with technical security ranging from excellent to very poor. It’s also futile to expect good support services in this category, unless the product has a well-working user forum that provides peer-support.

Donation financed, “begware”

This is a variant of the previous class. Some providers of free software ask for donations openly. This is like a product with a voluntary payment. A lot of people will use the product for free, but some will contribute a couple of bucks to cover the vendor’s expenses. Wikipedia is a good example. BTW, have you ever donated to them? I have and I think it’s very well spent money. The value I get in return is far greater.

Taxpayers’ money

Some free services are provided with tax-payers’ money. These are typically OK to use. Quality might vary tough, as the public sector often lacks the culture of customer service and competitiveness.

Upselling or service fees

Many vendors provide a basic product or service for free, and more functionality or capacity for a price. This is a nice way to let customers try it out and decide later if they need the paid version. Sometimes the product is entirely free and the business model is based on selling support services for it. There’s nothing wrong with this business model and the products are usually OK if the vendor is trustworthy. younited from F-Secure is a good example, like most other cloud services.

Bundles

Getting something for “free” when buying something else is a common marketing trick. It’s not really a free product, the pricing scheme is just set up to hide its true cost. A common example is receiving a “free” mobile phone or 4G-dongle when signing up for a 2-year subscription. Hardware prices are declining and many people have a misconception that these bundled items are worth more than they really are.

Pirated content

Some content is offered to you free of charge and with no strings attached, but the distributor lacks the right to distribute it. Distributing stuff without permission is illegal practically everywhere, but your status as receiver is not as clear. Whether it is a crime to download the stuff depends on your country’s legislation. Also remember that the common peer-to-peer sharing networks, like BitTorrent, both download and share at once. It’s also common to distribute malware masqueraded as pirated software. The safest way is to look for the content’s original vendor or distribution point, and download it from there. Then you will learn if it really is free, and lose the malware as an extra bonus.

Scams and malware

Malware and scams are often masqueraded as free offerings. Be extremely careful if you are tempted to sign up for anything that sends you “free” information as text messages. Your mobile phone number is a payment method and scammers can charge you for bogus messages sent to your mobile. It can be next to impossible to get them cleaned off the bill. What you think is a handy utility program may also turn out to be malicious software. If you can’t figure out why the tool is free, the real reason may be to plant malware in your computer or mobile device.

Let’s finish with a checklist for people considering using a free service or product:

  1. Find out who made it. Check if the vendor declares openly why the product is free.
  2. Check if the vendor offers paid alternatives to the free version and how they differ.
  3. Try to figure out what category the free offering belongs to.
  4. Is the vendor trustworthy? You shouldn’t use software from untrusted sources even if it’s free.
  5. Finally consider if the free offering really is what you want. Sometimes it’s a great alternative to expensive products, sometimes you pay a high hidden price just to save a couple of bucks. And sometimes the free alternatives just aren’t up to the task and you would be better off with a professionally made product. Consider if it really is smart to save a couple of dollars and insert potentially unreliable code in the system with all your irreplaceable content?
  6. If you still are uncertain, search for user opinions on the net. The true free gems, like Firefox and Linux, have huge user bases and you can find a lot of info about them. Be careful if you have problems finding independent opinions about a free product you consider.

Safe surfing,

What is a supercookie and why is it more important than you think?

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.   Image by Jer Thorp

F-Secure employee wins Inventor of the Year

20 Patents in 14 Years: How An Award-Winning Inventor Finds His Groove

We wouldn't be F-Secure without the talented and passionate researchers in our Labs. And today we'd like you to meet one whose inquisitive nature has driven him to become an inventor - and a prolific one at that. In his 14-year career with F-Secure, Jarno Niemelä has racked up an impressive 20 patents to his name and has filed 100 patent applications in total. His achievements recently won the title of "Salaried Inventor of 2014" from a group of Finnish inventors' organizations. I sat down to chat with Jarno about where he gets his ideas, and his advice for others. What area do your inventions focus on? I mostly focus on methods to help detect malware on a system, or methods of preventing malware from entering the system in the first place. How do your ideas come about? Inventions mostly happen in the evening when I'm not at work, and not even trying to think about it. I'll be working on some problem at work, and usually a day or two later, when I'm doing something totally unrelated on my own time, it hits me. I understand the problem and come up with a solution. The gym is a really good place for inventions. What motivates you to keep on inventing new solutions?   Inventions just happen, pretty much. Whenever I'm able to define a problem, I'm usually always able to come up with a solution. I am lucky to be researching in areas with problems that others have not yet solved. I'll be honest, I don't really like patents that much personally. The fact is though, that companies without patents would pretty much be at the mercy of the competitors. So in my view, patents are basically company self defense. Patents keep things in balance. Were you curious about things growing up? I've always kind of been inventive. You cannot learn to become an inventor, it's either something that's in your nature or it's not. And then you need to hone the talent and learn how to work within the patent framework. Another thing that is very important is good basic education and knowledge about the field. I owe a lot to Metropolia University of Applied Sciences where I studied for my engineering degree. Do you have any advice for people who have this inventive nature and are interested in filing patents? It all starts from defining and understanding the problem. Without a thorough understanding of the problem, you can't come up with a solution. Also, when it comes to patents, it's important to know what has previously been done in your area, and be clear in exactly how your invention is different from those. Otherwise your patent can be easily rejected by the patent examiner. And finally, patents are a long process so you need patience. It can take three to five years to get a patent approved. So this is not for hasty people. What is that rock you're holding? It's my trophy, a piece of Finnish bedrock! Inventors are the bedrock of new products. Do you have any certain goals for your inventions? Before I retire I would like to have at least 50 patents to my name. - Well, he's off to a great start. Congratulations, Jarno!
