Help 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.
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:
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… :)

Windows upgrades used to be like an international holiday, as PC users stepped up and shared what they liked -- much of Windows 7 --- and hated -- all of Windows 8 and Vista -- about the latest version of the world's most popular operating system. In this way, Windows 10 is the end of an era. This is the "final version" of the OS, which is now almost truly universal, meaning it has a similar feel across nearly all Windows-compatible device. After you step up to this version, there will be continual updates but no new version to upgrade to. It's the birth of "Windows as a service," according to Verge. So if you're taking free upgrade to the new version or getting a new computer are device, here are 5 things you need to know as you get used to the Windows that could be with you for the rest of your life. 1.Our Chief Research Office Mikko Hypponen noted Windows 10 still hides double extensions by default. “Consider a file named doubleclick.pdf.bat. If ‘hide extensions’ is enabled, then this will be shown in File Explorer as ‘doubleclick.pdf’. You, the user, might go ahead and double-click on it, because it’s just a PDF, right?” F-Secure Security Advisor Tom Gaffney told Infosecurity Magazine. “In truth, it’s a batch file, and whatever commands it contains will run when you double-click on it.” Keep this in mind when you do or DON'T click on unknown files. 2. You could end up sharing your Wi-Fi connection with all your contacts. There's some debate about whether or not Windows 10's Wi-Fi Sense is a security risk in that it shares your Wi-Fi connection with social media contacts by default, as Windows Phone has for a while now. ZDNet's Ed Bott says no, noting that "you have to very consciously enable sharing for a network. It's not something you'll do by accident." Security expert Brian Krebs is more skeptical, given how we're "conditioned to click 'yes' to these prompts." "In theory, someone who wanted access to your small biz network could befriend an employee or two, and drive into the office car park to be in range, and then gain access to the wireless network," The Register's Simon Rockman wrote. "Some basic protections, specifically ones that safeguard against people sharing their passwords, should prevent this." Gaffney notes that Wi-Fi Sense is “open to accidental and deliberate misuse.” So what to do? Krebs recommends the following: Prior to upgrade to Windows 10, change your Wi-Fi network name/SSID to something that includes the terms “_nomap_optout”. [This is Windows opt-out for Wi-Fi Sense]. After the upgrade is complete, change the privacy settings in Windows to disable Wi-Fi Sense sharing. 3. There are some privacy issues you should know about. Basically "whatever happens, Microsoft knows what you're doing," The Next Web's Mic Wright noted. Microsoft, according to its terms and conditions, can gather data “from you and your devices, including for example ‘app use data for apps that run on Windows’ and ‘data about the networks you connect to.'” And they can also disclose it to third parties as they feel like it. You can't do much about that but you should check your privacy settings and you can stop advertisers from know exactly who you are. Want a deep dive into the privacy issues? Visit Extreme Tech. 4. The new Action Center could be useful but it could get annoying. This notification center makes Windows feel more like an iPhone -- because isn't the point of everything digital to eventually merge into the same thing? BGR's Zach Epstein wrote "one location for all of your notifications is a welcome change." But it can get overwhelming. "In Windows 10, you can adjust notifications settings by clicking the notifications icon in the system tray," he wrote. "The click All settings, followed by System and then Notifications & actions." 5. Yes, F-Secure SAFE, Internet Security and Anti-Virus are all Windows 10 ready. [Image by Brett Morrison | Flickr]
You have all heard the classic mantra of computer security: use common sense, patch your system and install antivirus. That is still excellent advice, but the world is changing. We used to repeat that mantra over and over to the end users. Now we are entering a new era where we have to stress the importance of updates to manufacturers. We did recently write about how Chrysler reacted fairly quickly to stop Jeeps from being controlled remotely. They made a new firmware version for the vehicles, but didn’t have a good channel to distribute the update. Stagefright on Android demonstrates a similar problem, but potentially far more widespread. Let’s first take a look at Stagefright. What is it really? Stagefright is the name of a module deep inside the Android system. This module is responsible for interpreting video files and playing them on the device. The Stagefright bug is a vulnerability that allows and attacker to take over the system with specially crafted video content. Stagefright is used to automatically create previews of content received through many channels. This is what makes the Stagefright bug really bad. Anyone who can send you a message containing video can potentially break into your Android device without any actions from you. You can use common sense and not open fishy mail attachments, but that doesn’t work here. Stagefright takes a look at inbound content automatically in many cases so common sense won't help. Even worse. There’s not much we can do about it, except wait for a patch from the operator or phone vendor. And many users will be waiting in vain. This is because of how the Android system is developed and licensed. Google is maintaining the core Linux-based system and releasing it under an open license. Phone vendors are using Android, but often not as it comes straight from Google. They try to differentiate and modifies Android to their liking. Google reacted quickly and made a fix for the Stagefright bug. This fix will be distributed to their own Nexus-smartphones soon. But it may not be that simple for the other vendors. They need to verify that the patch is compatible with their customizations, and releasing it to their customers may be a lengthy process. If they even want to patch handsets. Some vendors seems to see products in the cheap smartphone segment as disposable goods. They are not supposed to be long-lived and post-sale maintenance is just a cost. Providing updates and patches would just postpone replacement of the phone, and that’s not in the vendor’s interest. This attitude explains why several Android vendors have very poor processes and systems for sending out updates. Many phones will never be patched. Let’s put this into perspective. Android is the most widespread operating system on this planet. 48 % of the devices shipped in 2014 were Androids (Gartner). And that includes both phones, tablets, laptops and desktop computers. There’s over 1 billion active Android devices (Google’s device activation data). Most of them are vulnerable to Stagefright and many of them will never receive a patch. This is big! Let’s however keep in mind that there is no widespread malware utilizing this vulnerability at the time of writing. But all the ingredients needed to make a massive and harmful worm outbreak are there. Also remember that the bug has existed in Android for over five years, but not been publically known until now. It is perfectly possible that intelligence agencies are utilizing it silently for their own purposes. But can we do anything to protect us? That’s the hard question. This is not intended to be a comprehensive guide, but it is however possible to give some simple advice. You can stop worrying if you have a really old device with an Android version lower than 2.2. It’s not vulnerable. Google Nexus devices will be patched soon. A patch has also been released for devices with the CyanogenMod system. The privacy-optimized BlackPhone is naturally a fast-mover in cases like this. Other devices? It’s probably best to just google for “Stagefright” and the model or vendor name of your device. Look for two things. Information about if and when your device will receive an update and for instructions about how to tweak settings to mitigate the threat. Here’s an example.

This is the fourth in a series of posts about Cyber Defense that happened to real people in real life, costing very real money. It was only just past 1 pm, but Magda was already exhausted. She had recently fired her assistant, so she was now having to personally handle all of the work at her law office. With the aching pain in her head and monstrous hunger mounting in her stomach, Magda thought it was time for a break. She sat at her desk with a salad she had bought earlier that morning and decided she’d watch a short online video her friends had recently told her about. She typed the title in the browser and clicked on a link that took her to the site. A message popped up that the recording couldn’t be played because of a missing plugin. Magda didn’t have much of an idea what the “plugin” was, which wasn’t surprising considering that her computer knowledge was basic at best – she knew enough to use one at work, but that was pretty much all. It was the recently sacked assistant, supported by an outsourced IT firm, who took care of all things related to computers and software. A post-it stuck to Magda’s desk had been unsuccessfully begging her to install an antivirus program. “What was this about?”, Magda tried to remember. At moments like this, she regretted letting the girl go. After some time, she recalled that her assistant had mentioned something about a monthly subscription plan for some antivirus software to protect the computers, tablets and mobile phones. This solution, flexible and affordable for small businesses like Magda’s firm, had also been also recommended by the outsourced IT provider. Despite a nagging feeling that something wasn’t right, she clicked “install”. After a few seconds, the video actually played. Magda was very proud of herself: she had made the plugin thing work! A few days later, she logged into her internet banking system to pay her firm’s bills. As she looked at the balance of the account, she couldn’t believe her eyes. The money was gone! The transaction history showed transfers to accounts that were completely unknown to her. She couldn’t understand how somebody was able to break in and steal her money. The bank login page was encrypted, and besides that, she was the only person who knew the login credentials... At the bank she learnt that they had recorded a user login and transfer orders. Everything had been according to protocol, so the bank had no reason to be suspicious. The bank’s security manager suggested to Magda that she may have been the victim of a hacker’s attack. The IT firm confirmed this suspicion after inspecting Magda’s computer. Experts discovered that the plugin Magda had downloaded to watch the video online was actually malware that stole the login credentials of email accounts, social networking sites and online banking services. Magda immediately changed her passwords and decided to secure them better. She finally had good antivirus software installed, which is now protecting all of the data stored on her computer. She recalled that her bank had long been advising to do that, but she had disregarded their advice. If only she hadn’t... Her omission cost her a lot of money. She was happy, though, that money was all she lost. She didn’t even want to imagine what might have happened if any of her case or clients information had been compromised. That would have been the end of her legal career. "This is why you should always use different browsers for different sorts of tasks," F-Secure Security Advisor Sean Sullivan explains. "Any browser you use for sensitive financial transactions should be used just for that, especially at work." To get an inside look at business security, be sure to follow our Business Insider blog.
