Share this with all your friends and make Facebook a better place

he-has-cancerHelp a sick child with cancer. Help us raise funds for this poor boy beaten by his stepfather. Learn how to help yourself if you have a heart attack and nobody is around. Isn’t Facebook a fantastic place, you can learn so much and get involved in things that matter through posts that your friends pass around. I’m sure you know what I’m talking about. We have all seen these posts that circulate on Facebook and other communities.

What do you think about them? Do you pass them on? Does this kind of messages play on your emotions? Do you like the feeling of helping a poor child somewhere in the word by clicking share? Have you ever tried to verify if the sad story is true? Or do you want to hold on to the dream that you are helping, and avoid checking the background even if there is a grain of doubt? Or are you one of the skeptics who dislike chain letters and write an angry reply instead?

Chain letter may be an old-fashion term from the snail-mail era. But that is really what we are talking about here. They are also called hoaxes, which refer to the content rather than the spreading mechanism. Our modern communities on the net provide an ideal environment for them. It has never before been so easy to share information with a large number of friends globally, just by a click. The content might be anything, but there are some easy ways to identify them.

  • They play on your emotions, often empathy or fear.
  • They tell you to share it with all your friends.
  • There’s often a shocking picture of a claimed victim. (The same picture is often reused in many different chain letters.)
  • It may claim that the victim gets money for each share. (This is never true.)
  • There’s no or very little details of the claimed victim to make it harder to debunk the story.
  • There’s no reference to news articles or other reliable sources, or the article is fake if there is one.

Here comes a couple of examples from different categories.

Help save baby with cancer is a really classical example. Who can resist a sick child? And that thing on the little boy’s face. OMG! In reality, this story is just made up and the boy doesn’t exist. Or the baby in the picture certainly exists, but he has appeared in many different chain letters and nobody knows where the picture comes from or if that thing is fake or real. The promise of one dollar per share is also just made up, there is no such commitment in reality.

YOU COULD SAVE A LOVED ONES LIFE BY KNOWING THIS SIMPLE INFORMATION!!! First aid and medical advice is another common chain letter category. I have attended a number of first aid courses at different levels, and this example is legit as far as I can tell. The described STR-rule is also well known and used elsewhere too. But how do you know that? If you can assess that, you don’t need the advice. And if you can’t, you have no clue if the advice is reliable and accurate. This one might be legit, but that can’t be said about all the other messages of this kind. They can in the worst case be directly harmful! (I have selected to not share one of those here.)

Facebook is not a good info source for matters of life and death. If you truly care about your loved ones and want to be able to help, then there is no substitute for professional first aid training. Trash all chain letters of this kind and sign up for a course today!

[Insert celebrity of your choice] found dead at Dominican Republic resort. This is really a sick form of humor. There’s a web-based generator that can generate hoaxes like this. It even creates fake news pages that can be passed around with the chain letter. I’m including the link to the generator here. I trust that you use it only to learn how to spot these hoaxes, not to make one yourself.

If you see some shocking news like this and the source isn’t one of the big news networks that you recognize, then turn to Google and get a second opinion before you hit share. Well, sites can be faked so Google is a good idea even if you recognize the news source.

But these chain letters are mostly harmless, you might think. Is it really that bad to pass one on? Well, they don’t harm the reader directly. Messages that trick you into downloading a file or opening a site that can contain malware is a different cup of tea. Phishing scams that trick you into entering secret data at a faked site are also truly harmful. Chain letters and hoaxes are not harmful in this way.

But that’s not the full story. There are still several reasons to avoid them:

  • Your own reputation. You may feel good when “helping a sick child”, but do your friends think the same way? Some of them may think you are gullible and easily fooled.
  • You create unnecessary noise on Facebook, or whatever community you are on. It may already be hard enough to spot the relevant posts from 500+ friends and a load of groups. Your friends do not need more junk to cover the valuable posts.
  • Things seem to replicate, especially problems. If you have a habit of sharing chain letters and hoaxes, you contribute to the culture among your friends. You signal that it is OK to share hoaxes and your habit will spread to some of them.
  • If you forward a message with some advice about first aid, a friend uses it and it tunes out to be bad advice. How would you feel? If you share info like this, you also carry responsibility for it.
  • Passing on jokes about someone killed in an accident is really sick humor, even if you might be in shock and believe it when you press share. Double-check before sharing and spare your friends that unnecessary shock.
  • If your account is compromised and misused to spread truly harmful content, it will blend in better in a stream of chain letters. Your friends are less likely to notice any difference and more likely to click on the malicious link from “you”.  Such post will however stick out if your normal posts are strictly no-nonsense.
  • A historical note. Old-school computer folks dislike chain letters because they were seen as a bad thing in the early days of e-mail. This was based on the limited capacity of the computers and telecommunications at that time. Technical capacity is not a problem anymore, today’s bottleneck is our capacity to process all the messages we get. But as said above, even if the technical capacity is there, it is still a bad idea to circulate chain letters.

And by the way. Why should you support this particular child? Just because you got a picture of him? There are probably thousands of real children with the same disease. You feel emotionally involved, that’s good. Let’s use your emotions for something more productive than just passing hoaxes around. Look up a local charity organization that work with children and make a donation while watching the picture. That really matters!

So, to summarize. Don’t feel bad if you have shared chain letters like this. As said, they do no direct harm. But I hope that as many as possible become aware of the downsides and start ignoring them. Our Facebook experience would be tidier.

So now you know how to spot a chain letter. Just click the share button and make sure all your friends on Facebook also know. Hey, wait… :)

Safe surfing,

The big things at CES? Drones, privacy and The Internet of Things

F-Secure is back from CES -- where the tech world comes together in Las Vegas to preview some of the latest innovations – some which might change our lives in the coming years, others never to be seen or heard again. Inside the over 200,000 square meter exhibit space, Drones flew, and made a fashion statement; hearing aids got smartphone apps; and 3-D printers printed chocolate. We made a stir of our own with Freedome. Our David Perry reminded the industry professionals that the mobile devices nearly all of them were carrying can do more than connect us. "I want you to stop and think about this," he told RCR Wireless News as he held his smartphone up on the event floor. "This has two cameras on it. It has two microphones. It has GPS. It has my email. It has near-field detectors that can tell not only where I am but who I'm sitting close to. This is a tremendous amount of data. Every place I browse on the internet. What apps I'm running. What credit cards I have. And this phone doesn't take any steps to hide my privacy." In this post-Snowden world, where professionals are suddenly aware of how much their "meta-data" can reveal about them. Privacy also played a big role in the discussion of one the hottest topics of 2015 -- the Internet of Things (IoT). The world where nearly everything that can be plugged in -- from washing machines to light bulbs to toasters -- will be connected to the internet is coming faster than most predicted. Samsung promised every device they make will connect to the net by the end of the decade. If you think your smartphone holds a lot of private data, how about your smarthome? "If people are worried about Facebook and Google storing your data today, wait until you see what is coming with #IoT in next 2-5 years," our Ed Montgomery tweeted during the event's keynote speeches, which included a talk from US Federal Trade Commission Chairwoman Edith Ramirez that tackled privacy issues on the IoT. Newly detected attacks on home routers suggest that the data being collected in our connected appliances could end up as vulnerable to snoops and hackers as our PCs. Some fear that these privacy risks may prevent people from adopting technologies that could eventually save us time, effort and energy. At F-Secure we recognize the promise that IoT and smart homes hold and we’re excited about the coming years. But we also understand the potential threats, risks, and dangers. We feel that our job is to enable our customers to fully enjoy the benefits of IoT and that is why we’re working on new innovations that will help customers to adopt IoT and smart home solutions in a safe and controlled way. It will be an exciting journey and we invite you to learn more about our future IoT solutions in the coming months. We at F-Secure’s IoT team would like to hear from you! Are you ready to jump on the IoT? What would your dream connected home look like? Or have you perhaps already set up your smart home? What are you worried about? How could your smart home turn into a nightmare? Read the rules and post your thoughts below for your chance to win one of our favorite things -- an iPad Air 2 16 GB Wi-Fi.

Authentication is a two way street!

In computer security, we throw around the word authentication all the time. It means a process or mechanism that is used to prove that you are you, (or that someone else or something else proves to you that they are they). Imagine yourself in a wartime  encampment. Someone approaches the sentry and the sentry calls out "Flash" The approaching soldier replies, "Thunder". This is a classic sign and countersign password set from World War II. The answer doesn't make any sense, and that's entirely on purpose. This was to prove to the soldier that he was at the right camp, and to the sentry that he was one of his own. There is a lot of chatter about signs and countersigns at one of my favorite blogs, and you can find it here. In the age of computers, things get a lot more complicated, but it's basically the same process. The website wants to know who you are, that you are the right person, and that is authentication. Now there are three methods of authentication, and they are: 1. Something you have, such as your driver's license, credit card, etc. 2. Something you know, such as a password. 3. Something you are, such as your fingerprint, retinal scan, or facial structure. This is called biometric authentication. On a computer, you actually have other things that can be known about you. There is your IP address (the address assigned to your computer on the internet), and your computer itself has a unique identifying serial number that isn't too difficult to read. Your operating system identifies itself, so do many other pieces of hardware and software on your computer, all unique, and all traceable back to you. One of the things that we use to protect ourselves is a kind of authentication called a password. This creates a lot of confusion in our lives, and small wonder--what follows is abstracted from my personal blog: Hackers are into lockpicking.  Every year at DEFCON there are lock picking contests and demonstrations, and you can buy the various tools (picks, bump keys, etc.) at Black Hat and DEFCON and many other such events. Now,  Timo Hirvonen tells me that this is a legitimate extension of learning Penetration testing, and I believe that that he is absolutely correct. I actually took up lockpicking in the summer of 1965, long before I ever dealt with a computer, but that's a story for another day. This is actually relevant, so you might want to stay with me, here. Take a look at the typical key pictured above. This is a key to a pin tumbler lock, and is the most common kind. Notice that the little notches in the key is at a different depth. The key would insert into the keyhole, which is in the part of the lock called a cylinder. When all the notches on the key line up properly, the pins line up so that the cylinder can turn. They have to be very accurate. Our example here is a five pin lock, so this key would only need notches cut in five places. The pins each have a number of discrete settings, and just to make it easy, let's imagine that there are five different settings for each pin. So how many possible combinations is that? Five times five is 25, but that's not it. Neither is five times five times five, or 125, correct. This would be a very simple lock, but it would carry a grand total of 3,125 combinations (five to the power of five). If each pin had six possible positions, you could raise that to 15,625 different combinations. With a pin tumbler lock, like the one shown here, there is also a restriction that the key has to be the right keyway (that's what they call all the channels and grooves that let the key fit into the lock). Each brand of lock uses a unique keyway which is why the key shop has hundreds of different key blanks hanging on a big rotating display. This is a very close model of an internet password. The number of pins is equivalent to the number of characters, and the number of possible positions is equal to the number of possible characters. This is why people keep telling you that a password is either strong or weak.  Let's look at it. Imagine a very short password of only two characters. If you use only numbers, then there are only ten possibilities for each character position. (0-9) so with that limitation, a two digit password using only numerals in base ten would give you only 100 possible combinations. If you had to type that in by hand it might be too much trouble, but a computer could feed those hundred combinations in less than a single second. The same two character password, if it used alphabetical characters, instead of numbers, would give you 676 possible combinations, instead of a hundred. Going to more places, or more pins, would give you an even greater combination, such as noted below. Well, you don't have to. You can get a program known as a password manager. The one we make here at F-secure is called KEY. We will take a look at that in just a little bit. First we want to make a couple of things clear.So, as you can see, it becomes much more difficult to crack a longer password, or a password with more available characters. That is not the end of the story. If you use a password made up of words that can be found in any dictionary, then a hacker could attack your password with a dictionary. Really. It's actually called a dictionary attack. So the best password would be gibberish.  How would you ever remember such a thing? 1. Passwords are extremely valuable, they are the online version of your keys, and eventually your car will start and your door will open to a password, rather than to a physical key. (I am very tempted to run off on a tangent, here)  You need to pay some attention to your passwords, because they are getting stolen left and right and because they open the door to your email, to your reputation and to your bank account. RUNNING OFF ON A TANGENT Car keys have gotten much more complicated over the last decade. First we added electronic door locks to the car, and the key acts as a remote control. Other functions come with that, including trunk release, and some kind of an alarm system. On top of all that, there is a secondary locking mechanism included with your key, where the car will only open for a key with both the proper physical keyway and tumbler pattern (( as described above)) AND the proper electronic signature.  So, in my car, for example, a new key needs to be cut and then programmed, and a new key costs almost $300! Now they tell you that's because it takes extra programming, but it's really because you NEED a car key, and based on the brand of car you drive, and I drive a Lexus, they hit you up for the highest price the traffic will bear. The circuitry isn't worth nearly that much, and neither is the 'programming'.  This is indicative of the state of the world. Drive a 1961 Buick, and you can buy a key for a buck, drive a 2001 Lexus, and the key is $300---the newest models skip the physical key entirely, and cost even more. They only charge what the traffic will bear. 2. It is very important that you not use the same password for everything. If you do, when somebody cracks one of your passwords they can find all of them. Some people use simple, same passwords for things they don't really care about (your Cookie Bakery discount code coupon, for example) but use stronger, unique passwords for more important things, like missile launch codes. 3. Do not use passwords that can be derived from the names of your pets, or the name of your spouse, or your boat, or anything that could ever be found out about you from a thorough analysis of your Facebook page. 4. Back up your data!  I use two different backups on everything, and a third backup on the most important data. I back up to a NAS (network attached storage) device, and to the cloud, and the third method is secret. Never put yourself in a situation where somebody could hack into your account and steal or delete anything you are going to need. Having said that, I want to say that too many things are authenticated these days (that's what a password is all about, authentication--it's when you prove that you are you) If you are doing a lot online you might actually be known via hundreds of passwords and who can possibly keep up with that? Nobody, that's who. It's just another example of FUTURE SHOCK, brilliantly predicted in 1971 by Doctor Alvin Toffler. My point? Maybe we are authenticating too much. Does your nephew's Bar Mitzvah really need me to get a password to reply to the evite? Do I really need a strong password to protect my registration to a trade show? The universal and always increasing demand for new passwords kind of cheapen the image they have to the public. If you need to keep track of a hundred passwords, then you might not put so much effort into managing them. Here at F-Secure we have a solution and it is called KEY. I use it on all my devices and I think it handles things very well indeed. It synchronizes all your passwords to all of your devices under a single master password. The keys are safely encrypted and cannot be extracted from either the install nor the cloud. It can and will generate new and stronger passwords for your most valuable data. You might want to look into it. Persevere, David Perry Huntington Beach, California 10/29/2014
